Packet Power™ Wireless Current Monitoring Module Manual

Safety summary and specifications

This general safety information is to be used by both the Power Wireless Current Monitoring

Module (CMM) operator and servicing personnel. Packet Power LLC assumes no liability for

user’s failure to comply with these safety guidelines. Please read this manual carefully

before proceeding.

This symbol is used throughout this manual to indicate critical safety

information. Failure to observe the information following this symbol may

result in injury or death.

CAUTION: This CMM and the area it is installed in may contain life threatening voltages.

Qualified personnel must disconnect all high voltage wiring before using or servicing the

CMM.

 CMM must only be connected to the type of power source indicated on the label.

 Do not overload the CMM by using the incorrect type of current transducer or

power source as this can result in a risk of fire or electrical shock.

 Disconnecting CTs from the CMM while there is current flowing through the

conductors on which the CTs are installed may result in exposure to very high voltages

capable of resulting in serious injury or death and damage to the CTs.

 The current transformer(s) used with the CMM must be appropriate to the amperage of

the circuit(s) on which they will be used as well as the correct output.

 Only current transformers approved by Packet Power should be connected to the

PMM. Using unapproved current transformers could result in inaccurate readings and

damage to the CMM device.

 Adhere to all local and national electrical codes and guidelines.

 Prior to installation, check to make sure the CMM has not been damaged.

 Store in a clean, dry location.

 Use indoors only and do not install in a wet location.

 Following installation in the final product, the connectors on the CMM and other

internal components such as the CT connection board and the 5V DC power supply

must be fully enclosed in a manner compliant with all relevant local electrical codes

and regulations.

 Failure to use the product in the specified manner may lead to injury or death and

damage to equipment.

The CMM is a Class 2 electrical device and does not require a safety connection to

electrical earth.

5VDCThe CMM shall only be powered by a 5 VDC source through the designated AC to

DC power supply.

Do not apply or remove the current transducers from live conductors.
