Chapter 2 Mounting

Environmental Conditions

The Accura 5500 should be mounted in a dry, dirt free location away from heat sources and very

high electric fields. To operate properly and effectively, environmental conditions should range

within the following guidelines

Items

Acceptable Range

Position

Indoor use

Operating Temp

-20 ~ 70C[-4℉ ~ 158℉]

Storage Temp

-40 ~ 85C[-40℉ ~ 185℉]

Operating Humidity

5 ~ 95% Non condensing

Enclosure Considerations

The enclosure the Accura 5500 is mounted in (typically a switchgear cabinet) should protect the

device from atmospheric contaminants such as oil, moisture, dust, and corrosive vapors, or other

harmful airborne substances. The mounting enclosure should be positioned such that the doors

may be opened fully for easy access to the Accura 5500 wiring and related components to allow

for convenient troubleshooting.

Warning

The meter should be installed in a switchgear cabinet or similar enclosure to ensure the terminal

strips on the meter base are not user accessible after installation.

Mount the meter in a dry location free from dirt and corrosive vapors. Once installed, no cleaning

of the device is necessary.

Page 16

Before You Begin

Before installing the meter, observe the instructions in this guide and read the safety precautions

presented on the “Installation Considerations” page.

Danger

Power up after the voltage and current wiring is completed.
