PMAC211 Multi-channel power meter
Installation & Operation Manual V1.0

Danger and warning！
 The device should be install by qualified people
 The manufacturer shall not be held responsible for any accident
caused by the failure to comply with the instructions in this manual.
Risks of electric shocks, burning, or explosion
 This device can be installed and maintained only by qualified people.
 Before operating the device, isolate the voltage input and power
supply and short-circuit the secondary windings of all current
transformers.
 Use a reliable voltage measurement device to make sure voltage cut
off.
 Put all mechanical parts, doors, or covers in their original positions
before energizing the device.
 Always supply the device with the correct working voltage during its
operation.
Failure to take these preventive measures could cause damage to
equipment or injuries to people.

Note :
 What is the meter ID?
You can find the S/N on the meter house. As picture 1-1
The last The last two numbers is the meter’s ID address. (But if the last two
numbers are “00”, then use “100” as meter ID address)
For example: if the S/N number is 15023876, then the meter ID is 76
If the S/N number is 15033800, the the meter ID is 100.
