CAUTION
When connecting the LV-DS in inside delta configuration, always install a main contactor or shunt trip
circuit breaker.
• Inside delta installation, externally bypassed
Non-bypassed models have dedicated bypass terminals, which allow the LV-DS 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).

NOTE
The bypass terminals on LV-DS-0255C are T1B, T2B, T3B. The bypass terminals on
LV-DS-0360C ~ LV-DS-1600C are L1B, L2B, L3B.
The fuses can be installed on the input side if required.
