SECTION 2 INSTALLATION
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 115V to a 208/230V input power supply.
Damage to the machine may occur.
The HandyPlasma
®
250 power source operates on 115 VAC,
1-phase input power and is equipped with a 8 ft. (2.4m), 3-
conductor 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 HandyPlasma
®
250 cutting package. It is
suggested that each step in this section be studied carefully
and followed.
2.2 EQUIPMENT REQUIRED
A source of clean, pre-filtered dry air that supplies 250 cfh at
75 psig (118 l/m @ 5.2 bar) is required for the cutting opera-
tion. The air supply should not exceed 150 psig (10.3 bar)
(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 HandyPlasma
®
250 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 HandyPlasma
®
250 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 mate-
rial and inspect for evidence of concealed damage
which may not have been apparent upon receipt of the
HandyPlasma
®
250. 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.
A line (wall) disconnect switch, with proper sized fuse or
circuit breaker (see Table 2.1), should be provided at the
main power panel.
*
Sized per National Code for 80°C rated copper conductors @ 30°C ambient. Not more than three conductors in
raceway or cable. Local codes should be followed if they specify sizes other than those listed above.
