3.3.1 DIN-Rail Mounting the Multilink ML1200

The Multilink ML1200 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 Multilink ML1200 requires one DIN-Rail mounting clip or latch for secure mounting. These may be ordered as Model # DIN-RAIL-ML1200. See a ML1200 viewed from the side, at the left, with model DIN-RAIL-ML1200 in place on the unit.

The Din Rail Latching clips are mounted on the upper side corners of the ML1200 unit. Two threaded holes are provided on the sides of ML1200 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 ML1200 is installed on a DIN Rail.

To install the ML1200 with the DIN-Rail brackets and latches attached to it, hold the ML1200 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 ML1200 inwards to a vertical position. The DIN-Rail latches and brackets are heavy duty, and will hold the ML1200 securely in position, even with cabling attached to the unit.

To release the ML1200 from the DIN-Rail mounting, press the top of the two DIN-Rail latches down simultaneously to release the ML1200 so that it can be dismounted by pulling the bottom out. Once the bottom of the ML1200 is rotated out, the DIN-Rail latch is not engaged and the ML1200 can be moved up and out, free of the DIN-Rail mounting.

If the Multilink ML1200 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 ML1200 unit is held out from the rear of the panel by the mounting brackets. The ML1200 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 separate items, e.g Model # DIN-RAIL-ML1200

3.3.1.1 Mounting Dimensions for ML1200 with metal brackets

Each Multilink ML1200 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 vertically, as shown below, 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 ML1200 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.
