Installing the Panel Mount Kit

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

Important: This procedure assumes that the drive has not been mounted or wired, and that incoming power is

Connecting Bus Bar Jumpers and Pressure Lugs to Input Power Terminals

Step 1. Attach the bus bar jumpers (item 1) between the input power terminals. Refer to figure 1 to confirm the

international codes. Failure to observe this precaution could result in damage to, or destruction of, the equipment.

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 a pressure lug and insulation to each pair of input terminals;

2) installing a pressure lug and insulation to each output power terminal;

3) Installing the coolant input and output hoses.

proper placement of the pressure lugs (item 2). a. Attach a bus bar jumper (item 1) behind and between terminals R1 and R2, locating a pressure

lug (item 2) on T1 in front of the bus bar. Place a 1/4-20 hex head screw and a 5/16” flat washer (items 5 and 3) through the assembly and fasten with a 5/16” flat washer and a 1/4-20 hex nut/ conical washer (items 3 and 4). Use the same fastener combination to fasten the bus bar jumper to R2.

b. Repeat step 1a to attach bus bar jumpers and pressure lugs to terminals S1/S2 and T1/T2. Important: Note that for T1/T2, the pressure lug must be installed on terminal T2. Step 2. Torque the six hex head screws (item 5) to between 80 to 90 in-lb (9.2 to 10.4 N-m). Important: 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 8) over each of the three input power leads (see figure 1). After tightening

the pressure lugs, fasten the insulation in place using two cable ties per lead (item 9).

Connecting Pressure Lugs to the Output Power Terminals

Step 1. Attach a pressure lug (item 2) to each output power terminal (terminals U, V, and W) using the

supplied fasteners. Place a 5/16-18 hex head screw and a 5/16” flat washer (items 6 and 3) through

the lug and the hole in the power output terminal and fasten with a 5/16” flat washer and 5/16-18 hex

nut/conical washer (items 3 and 7). Step 2. Torque the three hex head screws (item 7) to between 180 to 210 in-lb (20.8 to 24.2 N-m). Important: Step 3 below should be performed after the drive is mounted and at the time the output leads are

being connected to the output power terminals.
