M16 Cable Gland; Definition Of Short-Circuit And Overload Protection - IFM Electronic CR2032 Handbuch

M16 cable gland

Use a suitable cable to ensure ingress resistance of the M16 cable gland.
If the M12 connectors are used for the device supply and CAN connection, close
the terminal chamber with the supplied M16 cover plug (remove the cable gland
and insert the M16 cover plug).

Definition of short-circuit and overload protection

• Short-circuit test:
All outputs must withstand a short-circuit current limited to 60 A flowing
between output and ground (GND) or supply voltage (+V
Test duration: 3 minutes
• Overload test:
Outputs must not be destroyed by a 100 % overload.
(e.g. nominal switching current I
Test duration: 5 minutes
Fuses
To protect the whole system (wiring and module) the individual electric circuits
are to be protected using fuses according to the type of connection and jumper
settings. The M12 plugs are designed for max. 4 A, the clamps for max. 16 A.
