Install Power Block Enclosure

To install the Power Block enclosure, complete the following steps:

Prepare the Enclosure

1. Transport the crate to the installation site. Use lifting straps to stabilize.

   

2. Unfasten and lift off the crate front.

   

3. Use two persons to remove the crate:

   1. Uninstall four lag bolts from the crate bottom.

      

   2. Slide off the top, sides, and back of the crate.

      

4. Uninstall the lower door:

   1. Unfasten the two latches.

      

   2. Hold and tilt out the top of the door. Lift up and off.

      

5. Remove the package that contains the lower heat exchanger (dry box hex).

   You will install this later.

6. Remove two transparent shields (touchsafe panels):

   1. Loosen six captive screws by hand for each transparent shield (or, use a #5 Phillips screwdriver).

      

   2. Slightly rotate out the edge with the screws.

      

7. Remove two racks:

   1. Uninstall the two upper and two lower screws attaching the rack to the lower cabinet interior.

      

   2. Hold the outer edge of the rack and slide it out.

      

8. Uninstall four nuts from the base of the crate. Discard these nuts, washers, and bolts.

   

   Do not drag the bottom of the Power Block enclosure at any time. Gaskets underneath can be damaged.

 

Position and Secure the Enclosure Using a Forklift

To position and secure the enclosure using a forklift:

1. Insert forklift tines into slots at bottom of the enclosure. Position straps around upper half.

   

2. Move and hold enclosure above pedestal. Keep it elevated. Route wiring up through bottom of enclosure.

   

3. Slowly move the enclosure down toward the pedestal. Continue to pull wiring up through bottom.

   

4. Position the enclosure a few centimeters (inches) above the pedestal. Continue to move wiring out of the way. Align the screw holes with approximately 6 mm (1/4 in) of space between the enclosure and the pedestal.

5. The pedestal beam has rough alignment features (a) that assist in aligning the enclosure bolt holes with the mounting nuts in the pedestal.
   

   To properly engage the rough alignment features, position the enclosure approximately within:

   • ± 50 mm (2 in) front-to-back
     
   • ± 28 mm (1 in) side-to-side

   of the nominal hole alignment while lowering it onto the pedestal.

   

   After lowering the enclosure, if the holes (see Step 6 below) are not aligned, then re-raise the enclosure and try again with more precision.

6. Install seven hex bolts on each plate. Torque to 19 Nm (168 in-lb).

   

Position and Secure the Enclosure Using an Overhead Lift

You can use an overhead lift in tight locations where a forklift cannot reach or cannot be onsite to lift and move the Power Block into place.

Required Tools and Materials

The following tools and materials are required:

Tool Icons and Tool Descriptions

Nylon lifting straps (x2) Length: 4.572 m to 6.096 m (15 ft to 20 ft) Capacity: 567 kg (1250 lb)

Spreader bar (x1) (steel lifting beam with shackles) Length: 1 m to 2 m (3.28 ft to 6.56 ft) Capacity: 907.19 kg (2000 lb)   CAUTION: Lifting using the spreader bar is essential. Lifting from the forks without one: Will be unstable Will put extra forces on the straps and sheet metal Has not been tested, nor approved

To position and secure the enclosure using an overhead lift:

1. Prepare the enclosure for the overhead lift:

   1. Attach the spreader bar to your lifting device.

   2. Feed one end of each lifting strap through the fork lift tunnels.

   3. Attach both ends of the lifting straps to the spreader bar. The attachment points should be 1 m to 1.5 m (39.37 in to 59.06 in) apart and centered on the spreader bar.

These steps can be done with the spreader bar on the ground or in a raised position, centered above the enclosure.

2. After the spreader bar is in the raised position, ensure the following:

   1. The lengths of the lifting straps, both front and rear are approximately equal. Otherwise, the enclosure will tilt when raised.

   2. The straps are wrapped around the corners of the enclosure, roughly halfway up the height--above the side brackets, but below the top enclosure. This will prevent damage to the straps or the enclosure.

   

    

3. Follow Steps 2 through 6 of the previous section (Position and Secure the Enclosure Using a Forklift section).
