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.
