1. Disconnect the connectors required.
2. Strip insulation from cables and wires.
3. Crimp stranded wires with wire end sleeves.
4. Guide leads into corresponding connector terminals.
5. Fasten screws for the corresponding terminals using a screwdriver.
6. Plug connectors into the correct slots.
7. Equip the cable harnesses with strain relief.
5.4.1 Cable recommendation
Please note the following Maschinenfabrik Reinhausen recommendation when
wiring the device.
i
Ground the device with a protective conductor using the grounding screw
on the housing.
Note the phase difference of the secondary terminals for the current trans-
former and voltage transformer.
Connect the output relays correctly to the motor-drive unit.
Supply the voltage via separators and ensure that current paths can be
short-circuited. Fit the separator, clearly labeled and freely accessible, close
to the device's power supply. This ensures that the device can be replaced
with ease in the event of a defect.
To obtain a better overview when connecting cables, only use as many ca-
bles as necessary.
Observe the connection diagram [►Section 8.14, Page 59].
Only use the specified cables for wiring. Note the cable recommendation
[►Section 5.4.1, Page 27].
NOTICE! Damage to the terminals! Tightening the screws too tightly can
damage the screw terminals. When fastening the screw terminals, make sure
that the tightening torque is 0.4 Nm.
Wire the leads to the system periphery.
For wall mounting with housing (optional):
– When wiring the device, use the cable glands below the housing if neces-
sary.
– NOTICE! Damage to the device! If any cable glands remain open, the IP
degree of protection cannot be assured. Close off unused cable glands us-
ing dummy plugs.
Excessive line capacitance can prevent the relay contacts from interrupting
the contact current. In control circuits operated with alternating current,
take into account the effect of the line capacitance of long control cables
on the function of the relay contacts.
If you want to route Ethernet connections from a control cabinet or build-
ing, we recommend using fiber-optic cables (in accordance with the
IEC 61850-90-4 recommendation).
