Integration of the bridgeable contact (OC)
The integration is placed in a way that assures that OC can be bridged by the recall panel, but not by the in-
spection control (see Figure 7 to Figure 12).

Integration of NOC and door circuit
The safety circuit has to be cut at the end of the door circuit, after the last door contact. The end of the door
circuit is no longer directly connected to the safety circuit. Instead it is used as DCS-L input for LIMAX Safe
SG/SC. The neutral wire of the safety circuit has to be connected to LIMAX Safe SG/SC (to DCS-N) as well.
NOC-IN has to be connected to the beginning of the door circuit and NOC-OUT to the spot where the end of
the door circuit was cut (see Figure 7 to Figure 12).

8.3.7.1
Minimize the capacitive coupling
WARNING!
In order to minimize the capacitive voltage coupling on an open door
circuit, no 50Hz AC wires should be laid directly next to the wire which
supplies the door circuit. This applies to the travelling cable as well as
to the cable going through the elevator shaft.
Regarding the capacitive voltage coupling, wires leading safety circuit voltage (nominal 110 VAC or 230 VAC)
and wires leadings main power (nominal 230 VAC) immediately adjacent to the door circuit wire are critical.
Not critical are for example neutral wire or 24 VDC.
Figure 13 on the next page shows an example how the wires should not be installed (upper image). The exam-
ple on the lower image is the more advantageous installation.
