8.10.5. System overview of field wiring
Field wiring consists out of power supply (always including earth) and
communication (=transmission) wiring.
Most field wiring on the unit is to be made on the terminal blocks
inside the switch boxes. To gain access to the terminal blocks,
remove switch box service panel. Refer to the instructions
described in "7.1. Opening the unit" on page 4 how to remove
this panel and gain access to the inside of the switch box.
Cable tie mountings are provided at the wiring entries of the
switch box. See "7.3. Main components of the hydro module" on
page 5.
8.10.6. Connection of the unit power supply and
communication cable(s)
The power supply must be protected with the required safety devices,
i.e. a main switch, a slow blow fuse on each phase and an earth
leakage protector in accordance with the applicable legislation.
Cable requirements
Procedure
1 Open the switch box cover.
2 Using the appropriate cable, connect the power supply and
communication cable(s) to the appropriate terminals as shown
on the wiring diagram and according to the figure of chapter
"8.10.7. Routing" on page 16.
3 Fix the cables with cable ties to the cable tie mountings to
ensure strain relief and to make sure that it does not come in
contact with the piping and sharp edges. Never squeeze
bundled cables.
Note: only relevant field wiring is shown in the figure of chapter
"8.10.7. Routing" on page 16.
4 Close the switch box cover following the instructions described
in "7.1. Opening the unit" on page 4 in reverse order.
NOTICE
When the main switch is the in OFF position, it is
possible to lock the main switch using a suitable
padlock.
Refer to figure 11.
Keep in mind that in this case the padlock needs to be
opened and removed before it is possible to turn the
main switch to the ON position.
INFORMATION
The electrical wiring diagram can be found on the
inside of the switch box cover.
Install the unit, power supply cable and
communication cables at least 1 meter away from
televisions or radios to prevent image interference or
noise.
(Depending on the radio waves, a distance of 1 meter
may not be sufficient to eliminate the noise.)
NOTICE
Selection and sizing of the wiring should be done in
accordance with the applicable legislation based on the
information mentioned in the table below:

CAUTION
Select all cables and wire sizes in accordance with
relevant local and national regulations.
WARNING
After finishing the electric work, confirm that each electric
part and terminal inside the electric parts box is connected
securely.
To avoid receiving electric noise, be sure that the
cables are put in the correct bundle and routed in
the correct bundle tray as shown in the figure of
chapter "8.10.7. Routing" on page 16.
When wiring, route the cable bundles that are
outside the unit away from each other by at least
25 mm in order to avoid receiving electric noise
(external noise).
