Maximum number of option modules

The maximum number of option modules supported by the device is four. However, there are limitations.

Depending on the type and quantity of option modules attached to your meter, you may need to reduce your meter’s maximum operating temperature or limit the number of option modules. Refer to “Maximum operating temperature” for more information.

For a panel mount meter, one limitation on the number of modules that can be attached is the physical strength of the meter mounting hardware. If your meter is mounted in an area subject to vibration or other physical stresses, your meter’s ability to physically support multiple option modules and maintain a seal against the mounting surface may be affected. Refer to Mechanical characteristics for more information.

Do not exceed the maximum number of option modules.
Failure to follow these instructions can result in equipment damage.
