The D400 may be provided with an optional redundant power supply unit in Power Supply
Slot 2. The second power supply provides continuous power to the D400 in the event the
primary power supply unit fails.
Additional protection can be provided if a secondary external power source is available. In
the event the primary power source fails, an automatic switchover takes place to the
redundant power source to ensure continuous power to the D400.
The D400 supports the following power configurations:
• Single External AC Power Source
• Single External DC Power Source
• Two External AC Power Sources with optional redundant D400 AC-DC Power Supplies
• Two External DC Power Sources with optional redundant D400 DC-DC Power

Applying AC voltages to a DC-DC power supply may cause irreparable damage.
The D400 accepts power connections through two terminal blocks on the rear panel:
• Terminal block TB1 is reserved for connecting power from one or two external sources
to the D400.
• Terminal block TB2 provides contact closure outputs for power supply fail and system
fail alarms.
