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.
• Flush mounted IEDs should be possible to be added or replaced without excessive
dismantling.
