INSTALLATION
For a VM600 rack using a DC-input version of the RPS6U rack power
supply, the DC-mains power supply lead (power cord) must meet the
following requirements.
For later versions of the RPS6U (PNR 200-582-x00-02h or later) that define
the power as a total maximum output power of 330 W, the requirements are:
• The DC-mains power supply lead shall be rated for 30 A
DC
minimum
current at 105°C for an RPS6U with a 24 V
DC
input.
• The DC-mains power supply lead shall be rated for 6 A
DC
minimum
current at 105°C for an RPS6U with a 110 V
DC
input.
For earlier versions of the RPS6U (PNR 200-582-x00-01h or earlier) that
define the power as a rated power of 300 W, the requirements are:
• The DC-mains power supply lead shall be rated for 23 A
DC
minimum
current at 105°C for an RPS6U with a 24 V
DC
input.
• The DC-mains power supply lead shall be rated for 5 A
DC
minimum
current at 105°C for an RPS6U with a 110 V
DC
input.
For all versions of the RPS6U (PNR 200-582-x00-02h and
PNR 200-582-x00-01h), additional requirements are:
• The DC-mains power supply lead shall be at least 2.5 mm
