Before connecting to input power, make sure there is a line (wall) disconnect switch with fuses or circuit breakers
at the main power panel. You may either use the factory-installed input power cable (4/c, type SO (90 °C), 8 ft (2.4
m) length) or provide your own input power leads. If you choose to provide your own, make sure they are insu-
lated copper conductors. You must have two (single-phase) or 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 flexible conduit. Ensure the ground lead
is sufficiently 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-
