Circuit Breaker/Fuse Selection

The 8720MC-RPS unit does not contain a circuit breaker. Install an adequate
circuit breaker on the AC input power line. When an earth leakage breaker is
used, select a breaker equipped with harmonic suppressor.
Provide the required quantity of circuit breakers with supplemental contact
(CB) for all units connected in parallel. Because supplemental contact of this
circuit breaker does not conform with a load of 5 mA, use a relay with less than
5 mA for connection when a supplemental contact is connected with sequence
input PWR.

supplemental contact is connected with sequence input PWR.

Contactor Specifications

To help prevent electrical noise, peripherals of the 8720MC-RPS065 unit such
as magnetic contactors and relays must be provided with adequate surge
suppressor. Use CR filter for AC circuit and inverse-parallel diodes for DC
operation circuit.
The 8720MC-EF190-VB EMC filters, when used with 8720MC-RPS190
units provides the magnetic contactor.
