1. The primary power leads must be insulated copper conductors. Three

power leads and one ground wire are required. Either rubber covered

cable or conduit (flexible or solid) may be used. Table 3-1 provides

recommended input conductors and line fuse sizes.

2. Remove the top cover. Identify primary power input connection block,

chassis ground lug on the frame, and primary input terminal board. Refer

to Figures 3-1 through 3-6.

3. When using the provided strain relief, refer to Figure 3-2 for proper cable

strip lengths. It is important to follow the cable strip guide to ensure that

if the primary input cable is ever pulled from the strain relief, the input

conductors will be pulled from the Terminal Block before the ground lead

is pulled from the ground lug. Once stripped, thread the input and ground

conductors through the large strain-relief in the rear panel of the power

source. Connect the ground wire to the terminal lug located on the "A"

frame support. Connect the primary power leads to terminals L1, L2, and

L3 on the input power block. Secure the strain relief on the input cable.

4. Check all connections for proper tightness. Ensure all connections are

correct and well-insulated.

ELECTRIC SHOCK CAN KILL! Before

making electrical input connections to

the power source, "Machinery Lock-

out Procedures" should be employed.

If the connections are to be made from

a line disconnect switch, place the

switch in the off position and padlock

it to prevent inadvertent tripping. If the

connection is made from a fuse box,

remove the corresponding fuses and

padlock the box cover. If it is not pos-

sible to use padlocks, attach a red tag

to the line disconnect switch (or fuse

box) warning others that the circuit is

being worked on.

The chassis must be connected to an

approved electrical ground. Failure to

do so may result in electrical shock,

severe burns or death.
