Installing the Panel Mount Kit
Important: This procedure assumes that the drive has not been mounted or wired, and that incoming power is
not connected to the drive. Kit installation consists of:
1) connecting bus bar jumpers to input power terminals R1 and R2, S1 and S2, and T1 and T2,
and installing pressure lugs and insulation to each pair of input terminals;
2) installing pressure lugs on each output power terminal;
3) installing the coolant input and output hoses (not supplied);
4) installing a reactor cooling fan;
5) installing a printed circuit board cover.
Refer to figure 1 for all aspects of the installation procedure. The item numbers referenced in the procedure
correspond to the circled numbers in figure 1.
Connecting Bus Bar Jumpers and Pressure Lugs to Input Power Terminals
Step 1. Attach the bus bar jumpers (items 1, 2, and 3) between the input power terminals. Refer to figure 1 to
confirm the proper placement of the pressure lugs (item 8).
a.
Attach bus bar jumper “T” (item 3) between terminals T1 and T2, locating a pressure lug (item 8)
on T1 in front of the bus bar, and fasten it with a 1/2” flat washer, 1/2” split-ring lock washer, and a
1/2-13 UNC x 1.50“ hex head screw (items 9, 10, and 11). Use a 1/2” flat washer, 1/2” split-ring
lock washer, and a 1/2-13 UNC x 1.25“ hex head screw (items 9, 10, and 12) to fasten the bus bar
jumper to T2.
b.
Attach bus bar jumper “S” (item 2) between terminals S1 and S2, locating a pressure lug (item 8)
on S2 in front of the bus bar, and fasten it with a 1/2” flat washer, 1/2” split-ring lock washer, and a
1/2-13 UNC x 1.50“ hex head screw (items 9, 10, and 11). Use a 1/2” flat washer, 1/2” split-ring
lock washer, and a 1/2-13 UNC x 1.25“ hex head screw (items 9, 10, and 12) to fasten the bus bar
jumper to S1.
c.
Attach bus bar jumper “R” (item 1) between terminals R1 and R2, locating a pressure lug (item 8)
on R1 in front of the bus bar, and fasten it with a 1/2” flat washer, 1/2” split-ring lock washer, and a
1/2-13 UNC x 1.50“ hex head screw (items 9, 10, and 11). Use a 1/2” flat washer, 1/2” split-ring
lock washer, and a 1/2-13 UNC x 1.25“ hex head screw (items 9, 10, and 12) to fasten the bus bar
jumper to R2.
Step 2. Torque the six hex head screws (items 11 and 12) to between 72 to 76 ft-lb (100 to 103 N-m).
Important: Note that step 3 below should be performed after the drive is mounted and at the time the input
leads are being connected to the input power terminals.
Step 3. Install the insulation (item 18) over each of the three input power leads. After tightening the pressure
lugs, fasten the insulation in place using the cable ties (item 19).
!
ATTENTION: The drive is at line voltage when connected to incoming ac power. Disconnect, tag,
and lockout all incoming power to the drive before performing the following procedure. Failure to
observe this precaution could result in severe bodily injury or loss of life.
ATTENTION: The user is responsible for conforming with all applicable local, national, and
international codes. Failure to observe this precaution could result in damage to, or destruction
of, the equipment.
