INTRODUCTION TO THE VM600
Mk2
MACHINERY PROTECTION SYSTEM (MPS)
1.3 Connecting power
For a VM600
Mk2
machinery protection system (MPS) housed in a VM600
Mk2
/VM600 system
rack (ABE04x), the following versions of RPS6U rack power supply are available:
• RPS6U power supply for use with an external AC-mains supply.
• RPS6U power supplies for use with different external DC-mains supplies.
The RPS6U rack power supply must be used with an appropriate connection panel mounted
at the rear of the VM600
Mk2
/VM600 rack. Several types of these associated rear panels exist
in order to allow the connection of external AC-mains and/or DC-mains power to the rack.
NOTE: For further information, refer to the VM600 RPS6U rack power supply data sheet
and a VM600 machinery protection system (MPS) hardware manual.
As shown in Figure 1-1, one or two RPS6U power supplies can be installed in a
VM600
Mk2
/VM600 system rack (ABE04x). When two RPS6Us are installed in a rack, the
RPS6U on the right (slots 18 to 20) is power supply 1 (PS1) and the RPS6U on the left
(slots 15 to 17) is power supply 2 (PS2).
A rack can have two RPS6U power supplies installed for different reasons:
• In order to support rack power supply redundancy.
• In order to supply power to the modules/cards (non-redundantly).
NOTE: A VM600
Mk2
/VM600 system rack configuration with two RPS6U power supplies
(330 W) operating non-redundantly to supply power to the modules/cards is
typically only necessary for a full rack of modules/cards in an application where the
operating environment requires RPS6U output power derating.
The number and type of RPS6U power supplies installed in a VM600
Mk2
/VM600 system rack,
together with the number of modules/cards installed and the environmental conditions, helps
determine the mode of operation of the RPS6U power supplies as either redundant or
non-redundant.
NOTE: For further information on RPS6U power supply configurations, including
‘redundant’ configurations, refer to a VM600 machinery protection system (MPS)
hardware manual.
To connect power to a VM600
Mk2
/VM600 system rack:
• Determine the type of RPS6U rack power supply or supplies used by the rack: DC-input,
AC-input or both (that is, 1 × DC-input and 1 × AC-input).
See 1.3.1 Front panels.
• Connect the external mains power supply to the rack via the DC-input rear panel(s)
and/or AC-input rear panel(s), or combined AC-input and DC-input rear panel using
appropriate mains power supply leads (power cords).
