3.0 GENERAL
Proper installation can contribute materially to satisfactory and trouble-free
operation of the cutting outt. Each step in this section should be studied
carefully and followed as closely as possible.
3.1 INSPECTION AND PLACEMENT
1. Having removed the shipping container, and before removing the skid,
inspect for evidence of concealed damage which may not have been
apparent upon receipt of the unit. Notify the carrier of any defects or
damage at once.
2. Check the container for any loose parts. Check air passages on rear panel
of cabinet for any packing materials that may obstruct air ow through
the power supply.
The ESP-150 Power Source is equipped with one lifting eye that enables
hoisting the unit. Be sure the lifting device has adequate capacity to lift
the unit safely. Refer to the SPECIFICATIONS for the unit weight.
3. Mount the components of the TR-21 Truck Kit to the unit as covered by
Form F-14-413 packed with the truck kit.
4. The machine components are maintained at proper operating tempera-
tures by forced air which is drawn through the front panel louvers and
holes in the base and out the rear panel by a heavy-duty fan. Locate this
machine in an open area where air can circulate freely through the open-
ings. Leave at least two feet of clearance between the unit and wall or
other obstruction. The area around the unit should be relatively free of
dust, fumes and excessive heat. (Installingorplacinganytypeofltering

5. A source of clean, dry air that supplies a minimum of 250cfh (7.08 M
3
H at
110 psig) is required for the cutting operation. The air supply should not
exceed 150psig (10.3 bars) - maximum inlet pressure rating of the lter
regulator supplied with the package.
Precautionary measures should be taken
to provide maximum protection against
electrical shock. Be sure that all power is
o by opening the line (wall) disconnect
switch and unplug the power cord to the
unit when primary electrical connections
are made to the power supply.
ELECTRIC SHOCK CAN KILL! Precaution-
ary measures should be taken to provide
maximum protection against electric
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.
SECTION 3 INSTALLATION
This product is intended for industrial use. In a domestic environment
this product maycause radio interference. It is the user's responsibility
to take adequate precautions.

3.2 PRIMARY INPUT ELECTRICAL CONNECTIONS
1. A line (wall) disconnect switch, with fuse or circuit breakers, should be
provided at the main power panel. See Fig. 3. The primary power leads
should be insulated copper conductors, and include three power leads
and one ground wire. The wires may be heavy rubber covered cable, or
may be run in a solid or exible conduit. Refer to Table 1 for recommended
input conductors and line fuse sizes.
It is of the utmost importance that the
chassis be connected to an approved
electrical ground to prevent accidental
shocking. Take care not to connect the
ground wire to any of the primary leads.
Precautionary measures should be taken
to provide maximum protection against
electrical shock. Be sure that all power is
o by opening the line (wall) disconnect
switch and unplug the power cord to the
unit use proper lock out safety procedures
when making primary electrical connec-
tions to the power supply.

ELECTRIC SHOCK CAN KILL! Precau-
tionary measures should be taken to
provide maximum protection against
electric shock. Be sure that all power is
off by opening the line (wall) disconnect
switch by unplugging the power cord to
the unit or use proper lock out safety
procedures when making connections
inside of the power source.
2. 50 Hz Models - As shipped from the factory, the ESP-150 is congured
for the highest connectable voltage. If using other input voltages, the
links on the terminal board (TB) inside the unit must be repositioned
for the appropriate input voltage. See Figures 5a & 5b for input volt-
age congurations. To gain access to the terminal board, open the
access panel on the left side.

Before making any connections to the
power source output terminals, make
sure that all primary input power to the
machine is de-energized (o) at the dis-
connect switch.
3. Safety codes specify that the Power Cable GROUND wire be the last to
break connection should the cable be pulled out of the unit. Be sure to
cut and strip wire as shown in Figure 6.
4. Thread the input conductor cable from the wall disconnect switch through
the strain relief in the rear panel of the main contactor (MC). Connect the
primary power leads to the main contactor terminals (see Figure 7) using
UL listed pressure wire connectors. Also connect the ground wire to the
stud provided on the chassis base inside the left-rear of the cabinet. Secure
the input cable by tightening the strain relief coupling.
5. Recheck all connections to make sure that they are tight, well insulated,
and the proper connection has been made. Then close access panel and
reinstall fasteners.
A poor connection or failure to connect
work cable to workpiece can result in
fatal shock.
Failure to connect the workpiece to earth
ground will result in the opening of FUSE
F3 and CIRCUIT BREAKER CB1, disabling
the console.
