3.1 gENEral
Proper installation is important for satisfactory and trouble-free operation of the
ESP-50 cutting package. It is suggested that each step in this section be studied
carefully and followed closely.
3.2 EQuIPMENT rEQuIrED
A source of clean, dry air that supplies 50 cfh (118.0 l/m) at 60-75 psig (4.1 - 5. bars)
is required for the cutting operation. The air supply should not exceed 150 psig (10.
bars) (the maximum inlet pressure rating of the air filter-regulator supplied with the
package).
3.3 loCaTIoN
Adequate ventilation is necessary to provide proper cooling of the ESP-50. 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 ESP-50
power source and wall or any other obstruction to allow freedom of air movement
through the power source.
3.4 INSPECTIoN
A.
Remove the shipping container and all packing material and inspect for evidence
of concealed damage which may not have been apparent upon receipt of the
ESP-50. Notify the carrier of any defects or damage at once.
B. Check container for any loose parts prior to disposing of shipping materials.
C. Check air louvers and any other openings to ensure that any obstruction is
removed.

NOTE: If using 00(08) V input power, the ESP-50 must be reconnected for 00 V
use as directed in Section .7 and Figure -4.
If using 400 V input power, the ESP-50 must be reconnected as directed in
Section .8, Figure -5.
NOTE: The 08/0 V models are equipped with a plug for single-phase connection
only. The plug is mounted to a 4-conductor cable. If -phase connection is
desired, remove the plug and proceed as described.
Installing or placing any type of
filtering device will restrict the
volume of intake air, thereby sub-
jecting the power source internal
components to overheating. The
warranty is void if any type of
filter device is used.
ElECTrIC SHoCK CaN KIll! Precau-
tionary measures should be taken
to provide maximum protection
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 chassis must be connected to
an approved electrical ground.
failure to do so may result in
electrical shock, severe burns
or death.

A line (wall) disconnect switch with fuses or circuit breakers should be provided at
the main power panel (see 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 re-
ceptacle to line disconnect switch.
