5.3.4 Wall mounting
5.3.4.1
Overview
All case sizes, 1/2 x 19”, 3/4 x 19” and 1/1 x 19”, can be wall mounted. It is also
possible to mount the IED on a panel or in a cubicle.
When mounting the side plates, be sure to use screws that follows
the recommended dimensions. Using screws with other dimensions
than the original may damage the PCBs inside the IED.
If fiber cables are bent too much, the signal can be weakened. Wall
mounting is therefore not recommended for communication
modules with fiber connection;
Serial SPA/IEC 60870-5-103 and
LON communication module (SLM), Optical Ethernet module
(OEM) and Line data communication module (LDCM).
