Before connecting to input power, make sure there is a line (wall) disconnect switch with fuses or circuit break-
ers at the main power panel. You may either use the factory-installed input power cable 4/c, type SO (90 °C), 15
ft (4.6 m) length or provide your own input power leads. If you choose to provide your own, make sure they are
insulated copper conductors. You must have three (3 phase) power leads and one ground wire. The wires may
be heavy rubber covered cable or may be run in a solid or exible conduit. Ensure the ground lead is suciently
long inside the machine. In an event where the power cord is pulled from the machine, the ground lead must
not break from the ground connection before the power leads have broken from their connection. Refer to
Table 3-1 for recommended input conductors and line fuse sizes.
BEFORE MAKING ANY CONNECTIONS TO THE POWER SOURCE OUT
PUT TERMINALS, MAKE SURE THAT ALL PRIMARY INPUT POWER TO
THE POWER SOURCE IS DEENERGIZED OFF AT THE MAIN DISCON
NECT SWITCH AND THAT THE INPUT POWER CABLE IS UNPLUGGED.
THE CHASSIS MUST BE CONNECTED TO AN APPROVED ELECTRICAL
GROUND. FAILURE TO DO SO MAY RESULT IN ELECTRICAL SHOCK, SE
VERE BURNS OR DEATH.
ELECTRIC SHOCK CAN KILL! BEFORE MAKING ELECTRICAL INPUT CON
NECTIONS TO THE POWER SOURCE, "MACHINERY LOCKOUT PRO
CEDURES" 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 FUSEBOX, REMOVE THE CORRE
SPONDING FUSES AND PADLOCK THE BOX COVER. IF IT IS NOT POSSI
BLE TO USE PADLOCKS, ATTACH A RED TAG TO THE LINE DISCONNECT
SWITCH OR FUSE BOX WARNING OTHERS THAT THE CIRCUIT IS BEING
WORKED ON.
