Installing a rack
INSTALLATION
1.3.2 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 ABE04x rack) must employ a switch or circuit
breaker as a means of disconnection from the mains supply.
A VM600 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.
1.3.3 Supply wiring
A VM600 rack using the AC-input version of the RPS6U rack power supply is supplied with a
mains power supply lead (power cord). Power supply rear panels with two AC inputs for
independent mains supplies are supplied with two mains cables. However, no lead (cable) is
supplied with a VM600 rack using the DC-input version of the RPS6U.
NOTE: Refer to the VM600 RPS6U rack power supply data sheet and VM600 system rack
(ABE04x) data sheet for further information on the mains power supply lead (power
cord) supplied with a VM600 rack.
For a VM600 rack using a DC-input version of the RPS6U rack power
supply, the mains power supply lead (power cord) linking the VM600 rack
to the mains supply must pass through an external switch or circuit
breaker.
The switch or circuit breaker must be installed and used in accordance with
the manufacturer’s instructions in order to ensure the correct and reliable
protection of the VM600 rack.
The switch or circuit breaker must be chosen in accordance with the
version of the DC-input RPS6U rack power supply used, and in particular
the maximum permitted input current and output power.
The operator must have easy access to the switch or circuit breaker at all
times.
For further information, refer to the VM600 machinery protection system
(MPS) hardware manual.
In general, for a VM600 rack, the mains power supply lead (power cord)
used must be of sufficient cross-section to meet the power requirements of
the connected equipment.
In addition, the power supply lead (power cord) must meet certain
requirements depending on whether it is used with an AC-input version or
a DC-input version of the RPS6U rack power supply.
For further information, refer to the VM600 machinery protection system
(MPS) hardware manual.
