3 Varistor
1. Provide own contacts, supply voltage via contactor relay or
relay.
2. With the 100 V to 230 V versions, connect Varistor (U
N
= 275
V) or RC member (0.22 µF / 220 Ω) in parallel.
The connection terminal (23) for the potential equalisation line is
located on the housing next to the mains connection (12).
