3.1 gENEral
Proper installation is important for satisfactory and trouble-free opera-
tion of the Powercut 875 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 170l/m at 5.2 bar (360 cfh at 75
psig) is required for the cutting operation. The air supply should not
exceed 10.3 bar (150 psig) - the maximum inlet pressure rating of the
air filter-regulator supplied with the package. A brass 45
°
6.4mm (1/4")
NPT Female x 6.4mm (1/4") NPT male street elbow is recommended for
attaching the air hose to the regulator. This elbow will provide greater
clearance around the handle.
3.3 locatIoN
Adequate ventilation is necessary to provide proper cooling of the
Powercut 875. 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 Powercut 875 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 Powercut 875. Notify the car-
rier 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.
3.5 prIMarY ElEctrIcal INput
coNNEctIoNs (fIgurE3-1)
The Powercut 875 consoles are equipped with a 3.0m (10'),
4-conductor input power cable for 3-phase connection. If single-phase
connection is desired, tape back the red wire on the input power
cable.
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! precautionary
measures should be taken to provide maximum
protection against electrical shock. Be sure that
all power is off by opening the line (wall) discon-
nect 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 con-
figured for your input power supply. Do Not
connect a power source configured for 230 V
to a 400 V input power supply. Damage to the
machine may occur.
