2.5 PRIMARY ELECTRICAL INPUT
CONNECTIONS (FIGURE 2-1)
ELECTRIC SHOCK CAN KILL! Precautionary mea-
sures should be taken to provide maximum protec-
tion against electrical shock. Be sure that all power
is off by opening 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.
The PCM-500i power source operating on 230 V, 1-
phase input power is equipped with a 10-ft, 3-conductor
cable with plug. An optional mating receptacle (P/N
674540) is available. A line (wall) disconnect switch with
a 40-ampere fuse or circuit breaker should be provided
at the main power panel. The cable connecting the
disconnect switch to the receptacle should include three
(two power and one ground) No. 10 AWG insulated
conductors.
The chassis must be connected to an approved
electrical ground. Failure to do so may result in
electrical shock, severe burns or death.
NOTE: If using 208 V input power, the PCM-500i must
be reconnected for 208 V use as directed in
Section 2.7 and Fig. 2-2.
For all other PCM-500i power sources, they are equipped
with a 10-ft, 4-conductor input power cord with no plug for
connecting to 3-phase power. A line (wall) disconnect
switch, with proper sized fuse or circuit breaker (see
Table 2.1), should be provided at the main power panel.
The customer may connect the input power cord directly
to the disconnect switch or purchase a proper plug and
receptacle from a local electrical supplier. The cable
connecting the disconnect switch to the receptacle should
include four (three power and one ground) No. 12 AWG
insulated conductors.
2.1 GENERAL
Proper installation can contribute materially to the satis-
factory and trouble-free operation of the PCM-500i cut-
ting package. It is suggested that each step in this
section be studied carefully and followed as closely as
possible.
2.2 EQUIPMENT REQUIRED
A source of clean, prefiltered dry air that supplies 250 cfh
at 80 psig is required for the cutting operation. The air
supply should not exceed 150 psig (the maximum inlet
pressure rating of the air filter-regulator supplied with the
package).
2.3 LOCATION
Adequate ventilation is necessary to provide proper
cooling of the PCM-500i and the amount of dirt, dust, and
excessive heat to which the equipment is exposed,
should be minimized. There should be at least one foot
of clearance between the PCM-500i power source and
wall or any other obstruction to allow freedom of air
movement through the power source.
Installing or placing any type of filtering device will restrict
the volume of intake air, thereby subjecting the power
source internal components to overheating. The war-
ranty is void if any type of filter device is used.
2.4 INSPECTION
A. Remove the shipping container and all packing
material and inspect for evidence of concealed
damage which may not have been apparant upon
receipt of the PCM-500i. Notify the carrier of any
defects or damage at once.
B. Check container for any loose parts prior to dispos-
ing of shipping materials.
C. Check air louvers and any other openings to ensure
that any obstruction is removed.
