Connecting the expansion relief valve
1
1.
Use an intake funnel to connect a drain line to the outlet
(1)
of the expansion relief valve.
2.
Route as short a drain line as possible at a downward
gradient away from the product.
3.
Connect the drain line to an odour trap on an outflow or
route the drain line to the outside.
4.
Terminate the drain line in such a way that escaping
water or steam cannot cause injury to persons or dam-
age to cables and electronic components.
5.
When the drain is routed to the outside, ensure that the
end of the line is visible.
5.3
Electrical installation
Only qualified electricians are allowed to carry out the elec-
trical installation.
The cross-section of the connection wires is calculated by
the planner based on the installation conditions (e.g. cable
length, total input power for the product, etc.).
Danger!
Risk of death from electric shock!
▶
Switch off the power supply.
▶
Secure the power supply against being
switched on again.
▶
Ensure that the nominal mains voltage complies with the
technical data and that the power supply is sinusoidal.
▶
Connect the product using a fixed connection and a par-
tition with a contact gap of at least 3 mm (e.g. fuses or
power switches) (
→
Page 24).
▶
Route a three-phase power supply cable that complies
with the relevant standards through the grommet and into
the product.
–
Power supply cable: Flexible line
▶
In addition, install an on/off switch (on-site) in the power
supply adjacent to the product.
–
Clearance: 10 cm
▶
Ensure that the on/off switch completely disconnects the
L and N lines.
5.3.1
Connecting the power supply cable
1
1.
Install the enclosed duct screw connection for the
power supply's grommet
(1)
.
2.
Route the mains feed line through the grommet on the
rear right of the underside of the product. (

Page 5)
3.
Strip approx. 2-3 cm of the mains feed line and strip the
insulation from the conductors.
4.
Connect the connection cable to the relevant screw
terminals. (

Page 24)
5.
Ensure that the connection cable is mechanically fixed
in place in the screw terminals.
5.3.2
Setting operation with two electricity tariffs
1.
Remove the bridge at terminal X2 (ESC). (
→
Page 24)
2.
Connect the contact on the ripple control signal receiver
to terminal X2 (ESC).
5.3.3
Connecting the earth cable
1.
Connect the earth cable to the earth connection on
the product and to a suitable earth connection on the
house installation in order to prevent short circuits in the
product (e.g. caused by the penetration of water).
2.
Connect the earth cable to the earth connection on the
product's front cover.
