(b) Operation circuit connection
(i) Connect the operation power supply to the operation power supply terminals (P1 and P2).
There is no polarity.
(ii) Connect ON switch and OFF switch to the operation switch terminals (S1, S2 and S4). For the
operation switches, use the micro-loading switches (with approx. DC 24 V, 30 mA of switching
capacities) prepared at your side.
Note: For the voltage sharing items, the rush current (capacitor charging current 60A 1msec) men-
tioned later flows to the breaker and the fuse in the power supply circuit. So select the items
with care to prevent fusion and operation errors.
