6.3
Electrical installation/Commissioning
Safety instructions listed in Chapter 1.2 must be observed
-
All electrical installation to be carried out by an approved electrician in
accordance with presented manual and wiring diagrams.
-
The relevant standards, safety regulations (for instance DIN VDE 0100)
and technical connection regulations of the energy supply company
must be observed!
-
An all-pole mains switch/isolation switch, with at least a 3 mm contact
opening (VDE 0700 T1 7.12.2 / EN 60335-1) is mandatory by law!
-
Network configuration, voltage and frequency of the power source
must match the information on the rating plate.
6.4
Cable connection 230 V / control line (10 V=)
On the circuit board there are areas 230 V~ and 10 V= decoupled together. In order
to maintain the galvanic isolation several things must be observed with regards to
connection and cable wiring within the housing.
1. The cable entry of
NYM
(230 V~) always takes place through the cable entry at
the bottom left (fig 8).
2. The cable entry of
LiYY
(10 V=) control line always takes place through the cable
entry on the top right (fig 8).
The connection of the relay contacts must be according to the following
selection criteria:
-
230 V-consumers are introduced via input cable grommet
-
Low voltage consumers are introduced via the control line grommet
The relay terminal, combined with supply or control line, must take place in
one wire. Insertion of 2 wires in the grommet is not allowed.
In the wiring make sure that wires are placed not on the board, but on the edge
along the housing (fig 9/10).
For LiYY control line a maximum cable length permitted is 30m. A shield is not
necessary.
-
Prepunch grommet with a round tool or pierce directly with the supply line
(fig 7, Pos. 3)
-
Remove cable sheath to a length of 135 mm. Strip back each wire's
insulation about 8 mm.
-
Carefully slide cable through the grommet.
-
The wiring diagram (SS-1083) should always be used to ensure proper wire
placement.
-
Check sealing of the connection cables and cable wires clamp.
-
If mounted at the inlet spout the sheathed cable does not enclose evenly,
the spout must be additionally sealed with silicone. Otherwise, the IP
protection will be compromised.
-
The connection cable should be positioned in such a way that in case of
water entering, water may not penetrate along the cable. Cables must be
laid in such a way that they do not run over sharp edges.
-
Check the fan according to the intended use.
-
Supply voltage has to match the name plate data.
-
Ensure secure mounting and proper electrical installation of the device.
-
Check the freewheeling of the impeller.
-
All parts of the fan, especially screws and protective grid must be checked
for tightness. Do not lose included screws!
-
Ensure that the necessary protective guard is installed, as a device
cannot be operated without it.
-
During the trial run the fan is checked for vibrations and noise.
-
Power consumption has to match the name plate data.
