Prepare Installation Site

The CPF32’s pedestal mount can be installed either:

  • Into the ground by casting into new concrete

  • Onto an existing concrete surface

  • Onto a stacked parking platform

The required kit components, required tools, and installation steps vary depending on the type of installation. This topic provides basic guidelines for all approved installation types.

Always check local codes to ensure compliance. You may need to adjust the guidelines provided in this appendix to comply with codes that apply at your installation location.

Installation Overview

To install the CPF32 pedestal mount into the ground, you need the components listed below. These components are included in the shipping box with the pedestal and can also be purchased from ChargePoint by ordering a CPF32 Pedestal Mount Kit.

  • 8-32 X 9 mm (3/8 in) screws (4)

  • 16 mm (5/8 in) - 11 X 228.6 mm (9 in) grade 55 bolts (4)

  • 16 mm (5/8 in) - 11 hex nuts (16)

  • 16 mm (5/8 in) washers (12)

  • Installation Template 75-001163-01

When installing onto an existing concrete surface, you need only 6 galvanized hex nuts and 6 galvanized washers. Several required consumables are described below.

Casting into New Concrete

Before casting into new concrete, ensure the site is suitable for installation of aCPF32. The CPF32’s Clean Cord Technology requires space behind the power stub-up for the CMKClosed Cable Management Kit. To ensure adequate space, refer to theCPF32 Installation Template stapled into the center of this installation guide.

  • Always check local codes to ensure compliance. You may need to adjust these instructions to comply with codes that apply at your installation location.
  • The concrete block must measure at least 508 mm (20 in) on all sides.
  • The bolt threads must extend 63.5 mm (2.5 in) above the concrete.
  • The conduit must be between 19 mm (3/4 in) and a maximum of 32 mm (1.25 in) in diameter and extend 305 mm (12 in) above the concrete.
  • The service wiring must extend 1.8 m (6 ft) above the surface.
  • Refer to Install the Pedestal for detailed instructions on how to install the pedestal mount.

Preparation

Before pouring the concrete pad, ensure all pedestal mounting components are readily available at the installation site and that the conduit and service wiring is positioned as described on the installation template. ChargePoint recommends creating a jig to position the conduit before pouring the concrete.

Follow These Steps

  1. Install two nuts, with two washers captured between them, onto each of the four bolts. Lock them together so the lower end of the upper nut is located 152-165 mm (6 - 6.5 in) from the bottom of the bolt. This sets the length of the exposed threads.

  2. Insert the four bolts through the Plastic Bolt Installation Template. This ensures the relative position of the bolts, and ensures that the flange of the pedestal fits over the bolts.

  3. On the bottom of each bolt, install a nut, a washer, and a nut. Lock the two nuts together so that the lower nut aligns to the bottom of the bolt. These help anchor the template in the concrete.

  4. Immediately after pouring the concrete, push the bolts into the concrete 165 mm (6.5 in) deep. Ensure correct alignment and that the top 63.5 mm (2.5 in) of the bolts remain exposed. Rotate the bolts as you insert them to draw concrete into the threads.

You are now ready to install the CPF32’s pedestal mount as described in Section 2 of this installation guide.

Installing on Existing Concrete

If installing on existing concrete, review the site for suitability to install aCPF32. The CPF32’s Clean Cord Technology requires space behind the power stub-up for the CMKClosed Cable Management Kit. To ensure adequate space, refer to the CPF32 Installation Template included in this installation kit.

  • Always check local codes to ensure compliance. You may need to adjust these instructions to comply with codes that apply at your installation location.
  • Review the dimensions of the existing concrete slab. To safely mount a CPF32 charging station, the concrete must be at least 152.4 mm (6 in) thick.
  • At this thickness, all mounting bolts must be positioned at least 381 mm (15 in) from the front edge, at least 304.8 mm (12 in) from the side edges, and at least 152.4 mm (6 in) from the rear edge of the concrete slab.
  • If an existing charging station is already in place at the installation site, turn off all power to the station and disassemble according to the original manufacturer’s instructions. Cut away any existing bolts or non-power conduit stub-up to ground level. You may need to plug cut-away conduits at the slab end, and disconnect wiring at the other end.

Consumables Required

Consumable

Purpose

Push-on round cap, fits 16-17 mm (5/8 - 11/16 in) OD, 12 mm (1/2 in) inside height, packs of 100

Keeping the epoxy inside the drilled holes when the slab is only 152.4 mm (6 in) deep.

Follow These Steps

  1. Install two nuts with two washers captured between them. Lock them together so the lower end of the nut is located 152.4 mm (6 in) from the bottom of the bolt. This sets the length of the exposed threads.

  2. Use the Installation Template to mark the hole locations.

  3. Remove the template and drill four 19 mm (3/4 in) diameter holes 152.4 mm (6 in) deep into the concrete. When locating the template, consider the station’s total footprint. For reference, a template is included in this kit.

    • Bolts must be parallel after installation. Therefore, ensure drill holes are plumb by using a bubble level to check the angle of the drill after drilling 25-38 mm (1 - 1.5 in).
    • If installing over existing buried conduit, position the center of the template around the conduit stub-up.
    • You may need two drill bits: one for the concrete (with the pilot) and another for the rebar (without the pilot). Always start the hole using the standard drill bit, then switch to the rebar drill bit only if drilling through rebar.

  4. Remove all dust from inside the drilled holes using compressed air, a vacuum, and/or a brush.

  5. If the concrete slab is only 152 mm (6 in) deep, insert a plug in each hole to keep the epoxy in place until it hardens. Place the plug over the long end of a bolt and then use the bolt to push the plug to the bottom of the hole.

  6. Fill each hole with epoxy to about 64 - 76 mm (2.5 - 3 in) below the top. Continue immediately to the next step because the epoxy sets within about eight minutes.

    Inserting the threaded bolts displaces the epoxy, causing it to fill the holes to grade level. If the epoxy is below grade level, you can add more after the next step.

  7. Place the Installation Template over the holes. This ensures the relative position of the bolts and that the flange of the pedestal fits over the bolts.

  8. Insert the bolts through the template, into the holes. Rotate bolts as you insert them to draw epoxy into the threads.

    9. Epoxy is very thick. Rotating the bolts as you insert them is required to allow the epoxy to fully coat the threads of the bolts, reducing the amount of trapped air.
    You can leave the installation template in place.

  9. If needed, top up the holes with epoxy to grade level.

  10. Allow the epoxy to cure for at least 15 minutes* before removing the top nuts and washers, and 45 minutes* before applying torque to the nuts.

    * Epoxy cure times may vary depending on the type of epoxy. Refer to the cure times provided with the epoxy.

    You are now ready to install the CPF32’s pedestal mount as described in Install the Pedestal.

Installing onto a Stacked Parking Platform

Before installing the CPF32 onto a stacked parking platform, ensure that the site is suitable. Every stacked parking platform is different. Therefore, instead of step-by-step instructions, ChargePoint provides the following guidelines:

  • The CPF32’s Clean Cord Technology requires at least 50.8 mm (2 in) between the rear edge of the mounting plate and the wall to allow adequate clearance for the CMKClosed Cable Management Kit. Refer to the CPF32 Installation Template stapled into the center of this installation guide.

  • Before installing on the stacked parking platform, make sure that all pedestal mounting components are readily available at the installation site.

  • Always check local codes to ensure compliance.

  • Ensure you have adequate wiring. Service wiring for the CPF32 must extend 1.8 m (6 ft) above the platform’s surface, like any other type of CPF32 installation.

  • Refer to Section 2 of this installation guide for detailed instructions on how to install the pedestal mount. For stacked parking installations, it is acceptable to use a service cord (jacketed cable) without conduit inside the ChargePoint pedestal, provided the wiring is protected with appropriate bushings as it enters the pedestal.

  • Ensure that the pedestal is stable and does not move excessively when the station is in use or when the platform is in motion.
