Wiring Main Input Power
To wire the main input power terminal block:
1. Prepare the incoming three-phase power wires for attachment to 
the input power terminals by removing 10 mm (0.375 in.) of 
insulation.
2. Route the three-phase power wires (U, V, W, and PE) to your 1394 
system module.
3. Connect the system module ground wire from the system module 
single point bond bar to the bonded ground bar or bonded 
cabinet ground bus on the subpanel (as shown in Figure 3.7). For 
more information on bonding, refer to Chapter 1.
4. Open the front door of the system module and locate the 22 kW 
system module terminal blocks (refer to Figure 2.2).
5. Insert the incoming power wires into the terminal blocks as 
follows and tighten the four terminal block screws.
6. Gently pull on each wire to make sure it does not come out of its 
terminal block. Re-insert and tighten any loose wires.
IMPORTANT
Use caution not to nick, cut, or otherwise 
damage strands as you remove the insulation.
