ation of the fan insert
9.1 Electrical connection of the fan
insert
ER EC RF17 may only be connected accord-
ing to the wiring diagrams:
To prevent the unit and/or electric components
from malfunctioning as a result of reverse polarity
voltages and induction (incorrect ignition or glow-
ing/flaring of LED, energy-saving or neon lamps),
the unit and electric components connected in
parallel, such as room lighting, should be connec-
ted via a double-pole switch.
DANGER Danger to life from electric
shock.
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.
DANGER Danger to life from electric
shock/The unit will be damaged if installed in-
correctly 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.
Do not cut the power cable inside the housing too
short.
Risk of damage to unit in the event of
short-circuits.
→ Cut off and insulate PE conductor and indi-
vidual cable cores that are not required.
Always note the relevant specifications for elec-
trical installations and when fitting equipment. In
Germany, observe DIN VDE 0100 and the corres-
ponding 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 indi-
vidual 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 cor-
rectly 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 con-
trol variant. To do so, observe the wiring dia-
grams:
