Trident Planning and Installation Guide
Power Connections
An independent power source, equipped with its own fuse and switch, can be
shared by multiple baseplates. You should connect each baseplate to two,
independent power sources.
The selection of supply wiring depends on:
• Current ratings
• Temperatures
• Wiring lengths
In critical environments, at least one power source should be an uninterruptible
power supply (UPS), which can be shared by multiple Trident baseplates. The UPS
should be rated for the total number of baseplates to be powered and for the
duration of the maximum expected down time.
