Installing the universal power supply.
The universal power supply will provide a 5 VDC source to the remote interface board when
an alternate 5 VDC source is not available. The power supply shall be wired to an AC
source and shall have a means of overcurrent protection and disconnect from the upstream
source.
The input range for the power supply is 90-264 VAC at 50 or 60 Hz.
The power supply can be secured inside most electrical cabinets using adhesive tabs or
fasteners with mounting holes on the power supply.
Always provide overcurrent protection on the line side (brown cable) of the AC input to the
power supply.

Note: You must ensure that all connections (“taps”) being made to the load-carrying
lines satisfy relevant safety codes and local regulations. You are responsible for
understanding how to perform this connection. Failure to correctly perform this
connection could result in product failure and hazardous operating conditions.
Choosing the correct current transformers
The CMM can operate with a variety of standard current transformers (CTs). Only CTs
approved by Packet Power can be used with the CMM.
1. The CT must be approved by Packet Power for use with the CMM
2. The CT must be compatible with the version of the Interface Board that will be used.
3. The CT must be sized correctly for the maximum current of the circuit being
measured.
Comment [SV2]: Should we indicate which line
should be fused?
