Ensure that the enclosure keeps the MLSJ8 within its
required operating temperature range (considering a 24-watt
dissipation).
Do not mount the unit:
▪ in an area with excessive moisture, corrosive fumes, or
explosive vapours.
▪ where vibration or shock is likely to occur.
▪ in a location subject to electrical noise
The MLSUC500 / 1250 can be wall mounted by xing the
supplied wall mounting lugs to the corner holes on the rear
side as described in the supplied enclosure xing instructions.

The entry for the power wiring can be made by drilling a
conduit of around 20mm at the bottom or either side of the
enclosure.
The power wiring must be terminated at the MLS power
terminals and circuit breaker and terminal blocks. The MCB
and the terminal blocks are prewired to the MLSJ8 PSU in
the f actor y.
Note: the MLS circuit breaker and MLS PSU are pre wired
to the MLSJ8.

Caution: MLSUC500 / 1250 is not compatible with PoE
(Power over Ethernet) networks. Connecting to a PoE
network may cause the unit to stop functioning. In that
event, disconnect it from the network segment and powercycle the MLSUC500 / 1250.

RB2000
to further

RB2000’s
The MLSUC500 / 1250 assumes the role of Bus Master on
the MLS Spine. This means that all the RB2000s should
be given consecutive, unique non-zero addresses, refer to
RB2000 documents.
The last unit at each end of the MLS spine should be
congured to terminate the two RS485 signal pairs, A-B
and Y-Z. In the case of an RB2000 being the last device this
is simply a matter of sliding the switch behind the address
setting switches to the ON position.
The entry for wiring into the main enclosure can be made by
drilling a conduit of around 20mm at the bottom or either side
of the enclosure.
Note: The spine connections from the MLSJ8 are prewired to
the terminal blocks.
