AC Power Inlet Panel
The standard AC power inlet panel is described in this sec-
tion.
IEC AC Power Inlet Connector
The IEC AC power inlet connector mounted on the system
AC power inlet panel requires a properly configured IEC
compliant power cord, which enables worldwide system
operation by simply changing the power cord.
This system includes a 16/20 amp rated IEC inlet connec-
tor. Single phase 3600W/5000W systems include a non-
detachable power cord.
An appropriately rated power cord must be securely at-
tached to the welding system's IEC inlet connector. If the
correct power cord configuration is not included with the
system for the local AC power outlet at your location, an
appropriate IEC power cord should be available from a lo-
cal electrical parts supplier.
Power Switch/Circuit Breaker
The power switch/circuit breaker has a rocker type actua-
tor switch that will activate or deactivate the AC power
to the system. The power ON position is marked with the
internationally recognized
0
tion is marked with the
integrates an appropriately sized over-current protection
circuit breaker function in the generator.
If an over-current condition trips the circuit breaker, it will
automatically switch to the OFF position. If the overload
current that caused the circuit breaker to trip is due to a
transient condition, the circuit breaker can be reset by
switching the actuator back to the ON position. If when
resetting the circuit breaker after it has tripped, it imme-
diately trips again, there is likely an internal system mal-
function, and the generator will require service.
Do not repeatedly try to reset the circuit breaker. If it trips,
this will only cause more damage to the generator.

Chassis Grounding Stud
The chassis grounding stud is used to attach a protec-
tive earth ground to the generator. This will aid in the
suppression of electrical interference or radio frequency
interference (RFI) that is common in an industrial envi-
ronment. The chassis ground stud is
Proper system grounding is discussed in Section 2.

System Inputs/Outputs Connector
The
SYSTEM INPUTS/OUTPUTS
on the system I/O panel includes connections for all of
the basic system control input and output signals that
will typically be associated with an automated control
system. The cable attached to this connector includes
all of the available system control signals, which will
be controlled by an output card or output port on the
automation controller.
The user can determine which signals to use for each
particular welding application, but there must be at least
two connections to this connector or the generator will
always be in an E-STOP condition. All of the I/O signals
on this connector are electrically isolated (signals are
NOT referenced to chassis ground). Inputs are activated
when there is a 24VDC difference between the input pin
and the Input Common pin. The electrically isolated I/O
signals can be activated/monitored from an automation
controller with either sinking (NPN) or sourcing (PNP)
I/O depending upon how the isolated common connec-
tion is terminated. All inputs sink or source 10mA of
current from a 24VDC power supply. The total output
current cannot exceed 500mA when using the +22VDC
generator output (pin 1). If an external supply is used the
maximum current for each output is 400mA.
