space
GUID-2AF46E8C-25B3-4606-A768-E4B70E3D6B0A v10
The mechanical and electrical environmental conditions at the installation site must
be within the limits described in the technical manual and IEC60255-1, normal
environment.
•
Avoid installation in dusty, damp areas.
•
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 fibres and to enable maintenance and future modifications.
•
Ensure convection cooling around the case to minimize the heating effect
within the IED.
•
Avoid installation in dusty, damp places and where combustible
materials are present near the IED
