"Temperature Monitor" installation in a battery room

The "Temperature Monitor" should be secured against a wall or any vertical support:

–choose a location near the batteries and away from draughts which adversely affect the accuracy of temperature measurements;

–position the unit correctly ("on" light in the top left hand corner and cable fed through from the right-hand side);

–use the holes provided in the base plate to screw the unit to the vertical support (see figure 25);

–unless the connecting cable runs on the surface, break the knock-out in the unit base plate provided for cable entry;

–secure the cable by suitable means so that it does not pull on the unit.
