the main AC disconnect device so ensure the socket/outlet
is easily accessible.
• Close to the terminal equipment. Check the length of the 12V dc
output/alarm cable.
• Protected from excessive moisture and temperature. See
Specifications (on next page) for the recommended temperature
range.
2. Either:
• Mount the MPS12-30 on its back on a flat, firm surface, or
• Mount it on a wall with two screws (see below). If needed,
use wall anchors or plugs to suit the type of wall and the
weight of the MPS12-30.
Minimum wall space
required:
A = 130mm, B = 420mm
Screw spacing:
C = 80mm
Place the screws at least:
• 25mm from any side
obstruction (D).
• 70mm below any
obstruction (E).
• 350mm above any
obstruction (F).
How to turn on the MPS12-30
1. Plug the MPS12-30 into the wall socket and switch on the
socket. MPS12-30 will beep briefly.
2. Push in the AC power switch (
