Publication 1404-IN007F-EN-P - November 2009
Control Power
The power monitor draws a nominal 15VA control power. Catalog numbers
1404-M
xxxA-xxx require nominal control power of 120…240V AC or
125…250V DC. The power supply is self-scaling. Catalog numbers 1404-M
xxxB-xxx require
nominal control power of 24V DC.
Refer to Specifications on page 56 for acceptable control-voltage ranges and wiring
termination information.
We strongly recommend that you use a separate source of control power from the power
system being monitored. For applications where power system information is critical,
consider the use of a user-supplied uninterruptible power supply so that the power monitor
continues to operate during power system events such as significant sags, swells, and transient
disturbances.
You are required to connect your power-monitor control power through user-supplied
disconnecting means and overcurrent protection. We recommend a 1 A slow-blow fuse.
Status Inputs
ATTENTION
Do not apply an external voltage to a Status Input. These inputs have an internal source
and are intended for dry contact input only. Applying a voltage may damage the
associated input or internal power supply.
