MST-5C INSTALLATION

MST-5C Section

B-9

Electrical Power

-

Protection from electrical surge should be included in the planning of each

installation.

-

It is strongly recommended to have a backup power source to ensure life-

sustaining conditions in case of power failure (see figure 4).

-

It is also strongly recommended to put a backup thermostat to sufficient fan

and heating system parallel to the MST-5C module output (see figure 5).

-

The backup system and alarm must be thoroughly tested and verified as

working properly before using the ventilation system.

Mounting

-

The enclosure must be mounted in a location that will allow the cover to be

completely opened right up against the wall.

-

Fasten the four brackets to the four mounting holes on the back of the

enclosure, using the four screws provided with the brackets.

-

Then mount the enclosure on the wall by inserting screws through the

brackets’ adjustment slots, into the wall. Make sure to position the enclosure
so that all wires extend out of the bottom section of the enclosure.

-

The bracket slots also serve to adjust the position of the controller.

-

Once you have adjusted the controller position, tighten the four mounting

screws.
