INTRODUCTION TO THE VM600
Mk2
MACHINERY PROTECTION SYSTEM (MPS)
1.2.3 Supply wiring
A VM600
Mk2
/VM600 system rack (ABE04x) 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
Mk2
/VM600 system 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.
The AC-input rear panels with mains sockets used by VM600
Mk2
/VM600 system racks have
a power entry module that requires temperature derating when a rack operates in
environments with temperatures greater than 50°C (122°F).
NOTE: Refer to a VM600 machinery protection system (MPS) hardware manual for further
information on the temperature derating required for AC-input rear panels.
For a VM600
Mk2
/VM600 system rack using a DC-input version of the RPS6U
rack power supply, the mains power supply lead (power cord) linking the
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
Mk2
/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 a VM600 machinery protection
system (MPS) hardware manual.
In general, for a VM600
Mk2
/VM600 system 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 a VM600 machinery protection
system (MPS) hardware manual.
