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.
▶
Switch off the power supply.
▶
Secure the power supply against being
switched on again.
Danger!
Risk of death from electric shock!
The condensers are still charged even hours
after the power supply was disconnected.
▶
Wait until the condensers have
discharged.
The product's power supply must not be interrupted by a
timer.
5.3.1 Electrical connection
1. Ensure that the power supply complies with the regu-
lations for the country of installation and the IEE Wiring
Regulations.
2. Install a fixed separator using which the insulation can
be guaranteed to comply with the installation require-
ments in accordance with the conditions of overvoltage
category III.
3. Protect the product by installing the following elements.
–
Electrical partition, 8 A, with a contact gap of at
least 3 mm.
–
Residual-current circuit breaker, 30 mA, to protect
the electrical partition, 8 A.
4. If the power supply cable is damaged, it must be re-
placed by a competent person or electrician.
5.3.2 Carrying out the wiring
20 mm max.
1. Guide the extra-low and low-voltage cables through
different grommets on the rear of the product.
2. Ensure that the inner conductors' insulation is not dam-
aged when stripping the outer sheathing.
3. 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.
4. 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.

5.3.3 Connecting the cable for low-tariff or high-
tariff load relief
Note
The PV function and the management outside of
the power consumption cannot be used in parallel
as they use the same contact.
1. In order to keep the product's operating times as low
as possible during high-tariff periods of the power sup-
ply (where applicable), connect the electricity meter's
control contact.
2. Remove the protective cover. (→ Page 10)
3. Remove the black protective cover from the PCB.
4. Remove the red bridge from the energy supply com-
pany's connection terminal (1) (ESCO contact).
5. 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.
6. Use the plug (1) to establish the connection to the elec-
tricity meter's control contact.
–
Twin-core cable: 0.75 mm²
7. Inform the end user if the product is controlled via the
low-tariff contact, so that any programming of operating
times does not conflict with the high- and low-tariff peri-
ods.
