2. Route the condensate discharge pipe with a downward
gradient and without any kinks.
3. Fill the drain siphon with water.
4. Leave a small clearance between the end of the con-
densate discharge pipe and the drain siphon.
5. Ensure that the connection between the condensate
discharge pipe and the drain siphon is not air-tight.
6. Check whether the condensate drains off without any
problems.

Electrical installation

Only qualified electricians are allowed to carry out the elec-
trical installation.
Danger!
Risk of death from electric shock!
The mains connection terminals L and N re-
main live even if the product is switched off.

Carrying out the wiring
20 mm max.
Guide the extra-low and low-voltage cables through
different grommets on the rear of the product.
Ensure that the inner conductors' insulation is not dam-
aged when stripping the outer sheathing.
Remove max. 20 mm of insulation from the cables.
Note
If cables are stripped by more than 20 mm,
you must secure them using cable ties.
Fit the stripped ends of the conductors with crimp pin
terminals to ensure a secure connection that is free
from loose strands and to thus prevent short circuits.
Connecting the cable for low-tariff or high-
tariff load relief
In order to keep the product's operating times as low as
possible during high-tariff periods of the power supply
(where applicable), connect the electricity meter's con-
trol contact.
Remove the protective cover. (→ Page 11)
Remove the black protective cover from the PCB.
Remove the red bridge from the energy supply com-
pany's connection terminal (1) (ESCO contact).
Guide the cable through the grommet on the rear of
the product and through the grommet on the rear of the
electronics box.
Note
Ensure that the grommet is slit open as little
as possible to prevent air escaping while the
product is in operation.
