5.7 Shutdown Control Using External Contact
This section explains the method used to trip the breaker (turn the POWER switch
off) or turn the output off using external contact.
Possible electric shock.
•
The insulation of the external contact (S) and the connected cable
should be greater than the isolation voltage of the PAT. For the
isolation voltage of each model, see Chapter 9, “Specifications.”
• When using shielded wires for the connection, protect the
uncovered section of the shielded wire by using insulation tubes
with a withstand voltage greater than the isolation voltage of the
PAT.
To minimize the influence of noise on the output, use a two-core shielded wire or a
twisted-pair wire to connect the control terminals and the external contact. Make the
wires as short as possible. Susceptibility to the effects of noise increases as the wires
get longer. When wires are long, proper operation may be hindered even if a cable
with anti-noise measures is used.
When using a shielded cable, connect the shield to the - (neg.) output terminal.

To control the shutdown using an external contact, select the breaker trip setting
when the shutdown signal is applied in the CONFIG settings from the following two
modes.
• Not trip (default) (CF27: OFF)
The output turns off when pin 12 of the J1 connector is set low (TTL level). The
breaker is not tripped.
To recover, set pin 12 high (TTL) or open the pin and turn the POWER switch
off and then back on.
• Trip (CF27: ON)
The breaker trips when pin 12 of the J1 connector is set low (TTL level). To
recover, set pin 12 high (TTL) or open the pin and turn on the POWER switch.
