Figure 3-10 Rear Panel AC Breaker Switch

Emergency Stop Switch

Figure 3–9 is a simplified example that demon-
strates the basic requirements to interface with the
DPC II Plus on J902. This is excerpted from Ap-
plication Note AN201 available on our website.
Note that the emergency stop inputs cannot just
be tied together from multiple DPCs when used

on a common welding process. Multiple DPCs re-
quire individual contacts for each unit.

Check with your local safety compliance office
before altering the factory connections. The user
is responsible for complying with all requirements
of the safety regulatory agencies governing the
geographic location where the Dukane equipment
will be operated.

Electrical Power Switch

The rear panel AC breaker switch (Figure 3–10)
is wired in series with the front panel breaker
switch (shown in Figure 4-2). When the rear
breaker switch is off, it isolates the AC power feed
in the chassis for safety considerations. Both the
front panel and rear panel switches must be on to
supply AC power to the DPC generator.
