Step 4: Assembling the Kit
Parts
1. Feed the long narrow end of the DC- Bus bar through the slot in the top
cover.
2. Assemble a M6 flat washer, M6 lock washer and M6 x 55 mm (2.17 in.)
long screw through the top cover and into the DC- Bus bar at two
locations. Do not tighten!
3. Assemble a M6 flat washer, M6 lock washer and M6 x 55 mm (2.17 in.)
long screw through the Support Angle, top cover and into the DC- Bus
bar. Do not tighten!
4. Feed the long narrow end of the DC+ Bus bar through the slot in the top
cover.
5. Assemble a M6 flat washer, M6 lock washer and M6 x 55 mm (2.17 in.)
long screw through the top cover and into the DC+ Bus bar at two
locations. Do not tighten!
6. Assemble a M6 flat washer, M6 lock washer and M6 x 55 mm (2.17 in.)
long screw through the Support Angle, top cover and into the DC+ Bus
bar. Do not tighten!
7. Assemble a M6 flat washer, M6 lock washer and M6 x 30 mm (1.18 in.)
long screw through each Support Angle and into each DC Bus bar. Do
not tighten!
Step 5: Installing the
Assembled Kit Parts to the
Power Module
1. Position the assembled kit parts onto the power module and start ten (10)
screws M5 x 16 mm (0.63 in.) long into chassis. Do not tighten!
2. Align holes in each of the DC Bus bars with the holes in each side of the
laminate bus bar inside the power module.
3. Install M8 hardware to connect DC+ and DC- Bus bars to the laminate
bus bar. Do not tighten! The quantity of M8 hardware is based on rated
voltage (catalog string position 4) of the power module.
Step 6: Tightening the
Hardware
1. Refer to the table below for tightening order and torque requirement.
2. Apply a thin stripe of Torque Seal from each M8 screw head to the bus
