Connect the thermistor cable (supplied, P/N F01U074759)
to terminal block 3 of the power supply.
Mount the thermistor cable around the power supply as
shown in the figure below.
Secure the thermistor with the supplied adhesive tape
beneath the power supply in the center of the enclosure in
between the space reserved for the two batteries.
Slide the extension piece of the tamper switch to position
C as shown in the figure below.
If a wall tamper plug was installed (refer to Installing the
enclosure, page 14), the position of the expansion piece of
the tamper switch must be chosen in a way that lifting the
enclosure off the wall by > 5 mm leads to reliable activation
of the tamper switch.
