19.4.3.1 Overview
All case sizes, 1/2 x 19”, 3/4 x 19”,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, DNP3 and LON
communication module (SLM),Optical Ethernet module (OEM) and
Line data communication module (LDCM).
