INTRODUCTION TO THE VM600
Mk2
MACHINERY PROTECTION SYSTEM (MPS)
1.2.2 Circuit breaker
In some circumstances the operator must ensure a switch or circuit breaker is provided in
order to comply with the IEC/EN 61010-1 standard. This standard stipulates that permanently
connected equipment, such as a VM600
Mk2
/VM600 system rack (ABE04x), must employ a
switch or circuit breaker as a means of disconnection from the mains supply.
A VM600
Mk2
/VM600 system rack using the AC-input version of the RPS6U rack power
supply already have an ON/OFF switch or switches (and a fuse or fuses) at the rear of the
rack. However, this is not the case for the DC-input versions of the RPS6U rack power supply,
so an appropriately rated external circuit breaker or equivalent must be used.
