MULTILINK ETHERNET COMMUNICATIONS SWITCH – QUICKSTART GUIDE 7
2.4 DIN-Rail / Panel Mounting - ML1200/ML800
The Multilink ML1200/ML800 is designed for use in a “factory floor” industrial environment.
It is available with optional DIN-Rail brackets to mount it securely in a metal factory floor
enclosure, maintained vertically for proper convection cooling of the unit. The Unit requires
one DIN-Rail mounting clip or latch for secure mounting.
The Din Rail Latching clips are mounted on the upper side corners of the ML1200/ML800
unit. Two threaded holes are provided on the sides of the Unit for DIN-Rail mounting
purposes. See side view at the left. The required two screws are included with the DIN-Rail
brackets, and are no.10-32 X 3/8 PHIL. PAN w/star washer. The two heavy-duty Din-Rail
latches are designed as if that they can be manually accessed from the top when the Unit
is installed on a DIN Rail.
To install the Unit with the DIN-Rail brackets and latches attached to it, hold it in the side
vertical position with the bottom out, and with the top moved in toward the DIN-Rail.
Position the latches over the top of the DIN-Rail. Then, snap the latches into holding
position by moving the bottom of the Unit inwards to a vertical position. The DIN-Rail
latches and brackets are heavy duty, and will hold the Unit securely in position, even with
cabling attached to it.
To release the Unit from the DIN-Rail mounting, press the top of the two DIN-Rail latches
down simultaneously to release the Unit so that it can be dismounted by pulling the
bottom out. Once the bottom of the Unit is rotated out, the DIN-Rail latch is not engaged
and it can be moved up and out, free of the DIN-Rail mounting.
If the Unit is to be mounted on a DIN-Rail track, for proper convection cooling of the unit
there must be air space in the rear, as the Unit is held out from the rear of the panel by the
mounting brackets. . Note that there is air space in the rear, as the Unit is held out from the
rear of the panel by the mounting brackets. The ML1200/ML800 design uses the case for
cooling (patent pending), and needs to be mounted vertically with air flow space around it
in the front, rear, and sides.
The DIN-Rail mounting brackets and latches are optional and need to be ordered as
2.4.1 Mounting Dimensions for ML1200/ML800 with metal brackets
Each Unit is supplied with metal mounting brackets and screws to mount the unit securely
on a panel or wall. It is recommended to mount the ML1200/ML800 Unit vertically, for
proper cooling and long-life reliability. It is also advisable to mount the unit with space for
air movement around the top and the sides, typically a minimum of 1 inch.
Note that the metal brackets supplied hold the back of the Unit out from the panel or wall
behind it, creating a rear space of about ¼ inch or 1cm. This allows air circulation and
cooling of the rear part of the case.
For best cooling of the Unit, attach the metal brackets to metal (rather than wood or
plastic). Attaching to metal helps conduct heat away from the Unit through the metal
brackets and into the metal support structure.
Since the Unit has special internal thermal techniques (patent pending) to move the heat
generated by the electronic components inside into the case, the case may be quite warm
to the touch during normal operation.
