3. Wiring

Optional remote signalling contakt
Galvanically isolated switch contacts
integrated in the DRC MCM XT monitoring
module.
max. 350 V d.c. / 120 mA
250 V a.c. / 70 mA
Pin: 13-14 make contact (no)
21-22 breake contact (nc)
*) Illustration of the switch contacts in their normal state (all SPD to be monitored
are OK) with applied supply voltage and plugged-in DRC MCM XT.
max. 0.4 Nm
3.5 in-Ibs
Note:
Non-sheathed cables of intrinsically and non-intrinsically safe circuits which are routed in the same conductor bundle or
cable duct have to be isolated by means of an insulating layer or an earthed metal intermediate layer in accordance with
EN 60079-14. Isolation is not required if sheathed cables or cable shields are used in intrinsically or non-intrinsically safe
circuits.
