SeCTION 3 INSTAllATION
3.5 PRIMARY eleCTRICAl INPuT CONNeCTIONS (FIguRe 3-1)
NOTE: If using 208 V input power, the PCM-1125 must be reconnected for 208 V use as directed in Section 3.7 and
Fig. 3-2.
The PCM-115 consoles are equipped with a 10-ft, 4-conductor input power cable for -phase connection. If single-phase
connection is desired, tape back the red wire on the input power cable.
NOTE: The 208/230 V models are equipped with a plug for single-phase connection only. The plug is mounted to a
4-conductor cable. If 3-phase connection is desired, remove and discard the plug and proceed as described
above.
A line (wall) disconnect switch with fuses or circuit breakers should be provided at the main power panel (see Fig. -1 and
Table -1 for fuse sizes). The input power cable of the console may be connected directly to the disconnect switch or you
may purchase a proper plug and receptacle from a local electrical supplier. If using plug/receptacle combination, see Table
-1 for recommended input conductors for connecting receptacle to line disconnect switch.
CAuTION
WARNINg
eleCTRIC SHOCK CAN KIll! Precautionary measures should be taken to provide
maximum protection against electrical shock. Be sure that all power is off by open-
ing the line (wall) disconnect switch and by unplugging the power cord to the unit
when connections are made inside of the power source.
Be sure that the power source is properly configured for your input power supply.
DO NOT connect a power source configured for 208/230 V to a 460 V input power
supply. Damage to the machine may occur.
WARNINg
The chassis must be connected to an approved electrical ground. Failure to do so
may result in electrical shock, severe burns or death.
