6 Electrical connection
ATTENTION
The unit must be connected by a qualified electrician.
Protection class III (PC III) unit (IEC 61010-2-201 chap. 6.5.2.101.4).
The electrical supply must
- be provided only by PELV circuits (IEC 61010-2-201 chap. 3.111),
- not exceed 35 V DC during operation,
- not exceed 60 V DC in the event of a single fault and
- not exceed the permitted operating voltage of the unit (see data sheet).
Use energy-limited circuits for the electrical supply (IEC 61010-1 chap. 9.4). The energy of
the circuit can be limited at an operating voltage of 24 V by an overcurrent protection
device. The overcurrent protection device must switch off a current of 8.3 A in maximum
120 s. Observe the specific tripping characteristic. Possible overcurrent protection devices:
- fuse or
- non-adjustable and non-self-reclosing electromechanical device.
Separate the circuit from other, non-energy-limited circuits by at least basic insulation. The
separation of external circuits must comply with IEC 61010-2-201, figure 102.
u
Disconnect power before connecting the unit.
u
For cable lengths > 30 m use an additional protection against surge voltages to
IEC 61000-4-5.
ATTENTION
The device can be damaged by insufficiently tightened M12 connectors.
w
The IP rating indicated in the data sheet is only guaranteed if the M12 connectors are
firmly screwed.
u
Firmly screw the M12 connectors to the device.
For the scope of validity cULus:
Minimum temperature rating of the cable to be connected to the field wiring terminals: 70 °C.
Observe when connecting the device:
u
Use strain reliefs for cables connected to the device.
u
Cover the unused sockets with protective caps (E73004). Tightening torque 0.6...0.8 Nm.
If the device is permanently used in wet areas, the nut of the M12 industrial Ethernet connection
cable (e.g. E11898) may corrode.
u
Use a connection cable with a high-grade stainless steel nut.
