AC Power Inlet Panel
The standard AC power inlet panel is described here.
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.
The 240VAC i220 systems include a 16/20 amp rated IEC
inlet. 120VAC 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
local electrical parts supplier. Note that the system under-
voltage lockout will inhibit system operation if a North
American power cord configured for 120V is connected to
the system. A minimum of 200V is required for the system
to operate.
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 I symbol, the power OFF posi-
tion is marked with the 0 symbol. This power switch also
integrates an appropriately sized over-current protection
circuit breaker function in the press.
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 that will require service.
Do not repeatedly try to reset the circuit breaker. If it trips,
this will only cause more damage to the press.

Chassis Grounding Stud
The chassis grounding stud is used to attach a protective
earth ground to the press. This will aid in the suppression
of electrical interference or radio frequency interference
(RFI) that is common in an industrial environment. The
chassis ground stud is shown in Figure 3-3. Proper system
grounding is discussed on Page 9, and see Page 26 for RFI
Grounding.
