1) Valid for power sources without VRD specification on the rating plate.
2) Valid for power sources with VRD specification on the rating plate.The VRD function is explained in
the instruction manuals for the control panel, if the panel has that function.
Duty cycle
The duty cycle refers to the time as a percentage of a ten-minute period that you can weld at a cer
tain load without overloading. The duty cycle is valid for 104° F.
Enclosure class
The IP code indicates the enclosure class, i. e. the degree of protection against penetration by solid
objects or water. Equipment marked IP 23 is designed for indoor and outdoor use.
Application class
The symbol
indicates that the power source is designed for use in areas with increased
electrical hazard.

INSTALLATION
The installation must be done by a professional.
Mains supply requirements
High power equipment may, due to the primary current drawn from the mains supply, influence the
power quality of the grid. Therefore connection restrictions or requirements regarding the
maximum permissible mains impedance or the required minimum supply capacity at the interface
point to the public grid may apply for some types of equipment (see technical data). In this case it
is the responsibility of the installer or user of the equipment to ensure, by consultation with the
distrubution network operator if necessary, that the equipment may be connected.

Lifting instructions
8.2
Placing
Position the welding power source such that its cooling air inlets and outlets are not
obstructed.
8.3
Primary input
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
WHEN PRIMARY ELECTRICAL CONNECTIONS ARE MADE TO THE POWER SOURCE.
BE SURE TO CHECK YOUR INPUT LEADS WITH A VOLTMETER TO MAKE SURE ALL
POWER IS OFF.
