K1
CAUTION
When connecting the ASTAT XL in inside delta configuration, always install a main contactor or
shunt trip circuit breaker.
6.1.6 Inside delta installation, externally bypassed
Non-bypassed models have dedicated bypass terminals, which allow the ASTAT XL to continue
providing protection and monitoring functions even when bypassed via an external bypass contactor.
The bypass contactor must be connected to the bypass terminals and controlled by a programmable
output configured to Run (see parameters 7A~7I).
