7. Electrical connection
Electrical installation may only be performed by quali fi ed electricians in accordance with the installation
and operating manual and the national regulations, standards and guidelines in force:
•
EN, DIN and VDE speci fi cations, including all safety requirements.
• Technical connection conditions.
• Safety at work and accident prevention requirements.
This list does not claim to be complete.
Requirements should be applied under one‘s own personal responsibility.
• The electrical connections must be made as shown in the corresponding wiring diagrams and termi-
nal diagrams.
• The type of cable, size of cable and method of laying should be determined by an authorized elec-
trician.
• Low and extra-low voltage cables should be laid separately.
• An all-pole mains disconnection device with at least 3 mm contact gap must be provided in the supply
line.
• Use a separate cable inlet for each cable.
• Any cable inlets that are not used must be sealed so that it is airtight.
• All cable inlets must have strain relief.
• Create equipotential bonding between the unit and the duct system.
• Check all protective measures after the electrical connection work (earthing resistance, etc.)
Connection compartment / Connections on the unit
The connection compartment is inside the unit. You must fi rst remove the terminal box cover (see Fig. 7).
Every line to be connected must be fed through a separate cable gland and laid in the cable duct provided in
the centre tier of the device (see Fig. 7). It is possible for the cable glands to be placed either left or riht side
of the unit (see 4.1.) For this use the supplied cable glands,
fi ttings and cover plate. Cables that carry mains
voltage must be fastened with the tension relief devices available.
Unit supply cable
Connect the mains supply cable as shown in the wiring diagram. For the dimensioning of the line, observe
the unit‘s rating plate and the relevant guidelines. Suitable fuse protection should be provided.
Unit malfunction
If there is a malfunction on the unit, an error message appears on the display and at the same time swit-
ches a relay. A closing and opening signal is available (see wiring diagram). Electrical connection of the
changeover contact with U - 230 VAC and I
max
= 2A. (There is not any double insulation on the mains
cables).
Unit enabling
The unit can be switched on and off with an external potential-free contact (see wiring diagram). An
external voltage must never be applied to this connection. The control system would be destroyed. Any
devices that provide a potential-free contact (e.g. a time switch) can be used to control the unit. This
contact must be securely isolated from interference voltages because otherwise dangerous conditions
might occur in the event of a fault.
The extra-low voltage control cables must be laid separately from the mains cables.
• Electricity warning (hazardous voltage)!
»
Failure to observe the hazard may result in death, injury or damage to property.
→ Before performing any work on conductive parts, always disconnect the unit completely from
the electricity supply and make sure that it cannot be switched back on again.
