Electrical connection of the fan insert
ER EC RF17 may only be connected according to the wiring diagrams: Wiring diagrams.
To prevent the unit and/or electric components from malfunctioning as a result of reverse polarity voltages and induction (incorrect ignition or glowing/flaring of LED, energy-saving or neon lamps), the unit and electric components connected in parallel, such as room lighting, should be connected via a double-pole switch.
DANGER Danger to life from electric shock.
DANGER Danger to life from electric shock/The unit will be damaged if installed incorrectly with too long a power cable.
If the cable feed is too long inside the housing, the fan insert cannot be installed correctly. The power cable may be damaged when inserting the fan unit.
Risk of damage to unit in the event of short-circuits.
→ Cut off and insulate PE conductor and individual cable cores that are not required.
Always note the relevant specifications for electrical installations and when fitting equipment. In Germany, observe DIN VDE 0100 and the corresponding parts in particular.
- Take ambient conditions and technical data into account.
- Prior to accessing the connection terminals, switch off all supply circuits. Switch off mains fuse, secure against being accidentally switched back on and position a visible warning sign.
- Cut off and insulate PE conductor and individual cable cores that are not required.
- Remove power cable’s sheathing and cut to length.
- Wire power cable to the terminal box according to the wiring diagram.
- The degree of protection is only guaranteed:
- for intended installation;
- if the power cable is correctly guided through the intended cable grommet, if fan unit is correctly engaged in ER-UP housing and if cover is closed and engaged.
- Observe permitted duct cross-section of max. 1.5 mm².
Close the fan insert using the adapter board and the terminals in accordance with the desired control variant. To do so, observe the wiring diagrams: Wiring diagrams.
