4. Wiring
The terminals are shown in fig. 3 and on the wiring
diagram glued to the inside of the cover.
4.1 E-Bus (fi g. 6)
Cable type 24 AWG 7 x Ø 0,2 mm is recommended.
The to tal length of the E-Bus cable must not exceed
500 m. The E-Bus must be connected to the cen tral
control unit (B1-, B2, B3, B4+). It may be routed in
parallel to other accessories. If shielded cable is used,
all the shields must be connected at one point, e.g. at
E-Bus to other
an NC terminal.
accessories
4.2 Tamper contact
If the SMT 12 circuit board is not fitted in the SAT
12 housing, the plug connector (fig. 3 W) must be
connected to an external tamper contact or be short-
circuited. Use the socket connector provided to connect
