RSM-48/50 and RSM-24/100 Cabinets: The unit should be mounted to the rack using four #12 -24
x 1/2" screws in each bracket. RSM-48/30 and RSM-24/50 Cabinets: The unit should be mounted
to the rack using two #12 - 24 X 1/2" screws in each bracket. A captive type of drive such as Phil-
ips head is preferred to eliminate the possibility of slippage and scratching of the units exterior.
4.3.1
3 Module Shelf
The 3 Module shelves have been designed for mounting in a 19" or 23" EIA standard relay rack.
Mounting brackets are universal on this shelf for 1" or 1-3/4" spacing plus reversible for 19" or 23"
mounting configurations. These shelves are shipped from the factory arranged for 19" centre mount-
ing. To adapt to 23" mounting, remove the three attaching screws, then flip the brackets so that the
large flange is against the shelf chassis, re-attach with mounting screws. For flush mounting attach
the brackets to the cabinet via the mounting holes located near the front of the cabinet.
4.3.2
4 Module Shelf
The 4 Module RSM-48/50 and RSM-24/100 shelves are not adjustable and must be ordered for
centre or flush mounting from the factory. The 4 Module RSM-48/30 and RSM-24/50 shelves can
be configured for flush mount or center mount (5" or 6" offset).

Input Connections
Grounding Instructions: This Module should be connected to a grounded, metal, permanent wiring
system; an equipment grounding conductor should be run with circuit conductors and connected to
equipment grounding terminal(s) of the shelf. Connections to the shelf should comply with all local
codes and ordinances.
4.4.1
Feeder Protection / Sizing
Each module should have a dedicated protection breaker if possible. If it is preferred that the input
breaker of the Module trips before the feeder protection breaker, the feeder breaker should have
the next highest rating from the Module's A.C. input breaker. The size of the feeder breaker will be
dependent on whether it is a single phase or three phase source. See specifications for recom-
mended feeder protection.
