2.5 PRImARY eleCTRICAl INPUT
CONNeCTIONS
eleCTRIC ShOCK CAN KIll! Precautionary 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 Prest-O-Lite
®
380 power source operates on 230 VAC,
1-phase input power and is equipped with a 8-ft, 3-conduc-
tor cable. The customer is responsible for supplying a plug
with a NEMA 6-30 rating minimum ir desired.
The chassis must be connected to an approved electrical
ground. Failure to do so may result in electrical shock,
severe burns or death.
2.1 GeNeRAl
Proper installation will insure satisfactory and trouble-free
operation of the Prest-O-Lite
®
380 cutting package. It is
suggested that each step in this section be studied care-
fully and followed.
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 rat-
ing of the air filter-regulator supplied with the package).
2.3 lOCATION
Adequate ventilation is necessary to provide proper cooling
of the Prest-O-Lite
®
380 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 clear-
ance between the Prest-O-Lite
®
380 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 warranty is void
if any type of filter device is used.
2.4 INSPeCTION
A.
Remove the shipping container and all packing ma-
terial and inspect for evidence of concealed damage
which may not have been apparent upon receipt of
the Prest-O-Lite
®
380. Notify the carrier of any defects
or damage at once.
B.
Check container for any loose parts prior to disposing
of shipping materials.
A line (wall) disconnect switch, with proper sized fuse or
circuit breaker (see Table 2.1), should be provided at the
main power panel.
C.
Check air louvers and any other openings to ensure
that any obstruction is removed.
