Chapter 5
Installing the IED
1 Overview
The mechanical and electrical environmental conditions at the installation site must be within
the limits described in the IED technical data. Dusty, damp places, places susceptible to rapid
temperature variations, powerful vibrations and shocks, surge voltages of high amplitude and
fast rise time, strong induced magnetic fields or similar extreme conditions should be avoided.
Sufficient space must be available in front of and at the rear of the IED to allow access for main-
tenance and future modifications. Flush mounted IEDs should be mounted so that IED modules
can be added and replaced without excessive dismantling.
