6. Electrical connection
DANGER
Electric shock
Death or serious personal injury
‐Switch off the power supply before making any
electrical connections. Make sure that the power
supply cannot be switched on accidentally.
‐An external main switch must be installed to ensure
that the controller can be switched off. Remember to
indicate where the main switch is located by placing a
label or similar marking on the controller.
‐If national legislation requires a Residual Current
Device (RCD) or equivalent in the electrical installation,
this must be type B or better, due to the nature of the
constant DC leakage current.
WARNING
Electric shock
Death or serious personal injury
‐All cables must be insulated. Ensure space between
voltage cables and signal cables.
WARNING
Hot surface
Death or serious personal injury
‐Allow the system to cool down before any connections
are made.
‐Wear protective gloves when working with hot
surfaces.
CAUTION
Electromagnetic interference
‐If the product is installed in a residential area,
supplementary measures are required as the product
may cause interference. These measures must reduce
electromagnetic emissions to prevent interference from
cell phones and from the reception of radio and
television broadcasts.
• The system must not be installed unless external
scalding protection is installed.
• Do not power on the system until all connections to
valves, sensors and bus-connected devices are done,
as specified in the following sections.
• All installation work must only be carried out by
qualified and authorised persons.
• The system must be supplied with 230 V for the
general power supply. Using the 230 V supply, the
system creates supply voltages for the valves
specified in the specific installation.
For the connection of external accessories, refer to the
product's own manual.
The residual-current circuit breaker must be marked as follows:
TM066230
Take into account the total leakage current of all the electrical
equipment in the installation.

1. Check that the supply voltage and frequency correspond to the
values stated on the nameplate.
2. Cut the power cable as short as possible.
3. Lead the power cable through one of the cable glands.
4. Cables with live voltage must be insulated along their full
length, and they must be separated from low voltage wires,
parts and enclosures.
5. Connect the power cable according to the relevant wiring
diagram. Note that all wires must be secured inside the
controller using cable ties.
