SECTION 3 INSTALLATION

The primary power leads must be insulated copper conductors. Three power leads and one ground wire are re-

quired. Either rubber covered cable or conduit (ﬂexible or solid) may be used. Table 3-1 provides recommended

input conductors and line fuse sizes.

Remove the top cover. Identify primary power input connection block, chassis ground lug, and primary input

terminal board. Refer to Figures 3-3 and 3-4.

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 con-

ductors will be pulled from the terminal block before the ground lead is pulled from the ground lug. 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.

Check all connections for proper tightness. Ensure all connections are correct and well-insulated.

THE CHASSIS MUST BE CONNECTED TO AN APPROVED ELECTRICAL

GROUND. FAILURE TO DO SO MAY RESULT IN ELECTRICAL SHOCK,

SEVERE BURNS OR DEATH.
