4.1
Checking environmental conditions and mounting
space
The mechanical and electrical environmental conditions at the installation site must be
within the limits described in the technical manual.
•
Avoid installation in dusty, damp places.
Avoid 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.
•
Check that sufficient space is available.
Sufficient space is needed at the front and rear of the IED to allow access to wires and
optical fibers and to enable maintenance and future modifications.
For more details of the checks required for different type of mounting methods, see
the respective chapters, such as rack mounting or flush mounting.
