AXM-WEB2 for Acuvim II Series Power Meter

www.accuenergy.com

V: 1.10  Revised: January 2020

6

4. Installation Method

The AXM-WEB2 module is linked to the Acuvim II series meter by a communication plug. Other 
extended modules such as the IO modules can be linked to the Acuvim II series meter through 
the AXM-WEB2.

1) Remove cover from the back of the Acuvim II series meter which will expose the socket.

2) Insert the installation clips to the grooves in the Acuvim II series meter and then press the 

AXM-WEB2 module lightly to establish a linking between meter and module.

3) Tighten the installation screws.

NOTE:

 Installation with power to the meter is forbidden.  The module must be installed/unin-

stalled while the meter is powered off.
