For the power supply, use the power cable attached to the boiler or cable
types H05VV-F 3 x 1 mm
2
or 3 x 1.5 mm
2
. The earthing cable must be
longer at the connection in order to guarantee that this connection is the
last cable to rupture in the event of a hazard.
We recommend the installation of a mains isolator upstream of the Para‐
mount. This should isolate all poles and provide contact separation of at
least 3 mm.
Important
For boilers with a total rated output of more than 100 kW, a switch
(emergency switch) must be fitted in front of the boiler outside the
room where the boiler is installed. This switch should be identified
by a sign featuring the text "EMERGENCY SWITCH FOR
BOILER".
All connected components must be executed compliant with VDE
regulations. Always apply strain relief to connecting cables.
Cable types
Danger of electric shock
Danger to life! Risk of injury or a risk to life from electric shock!
The use of rigid lines (e.g. NYM) is not allowed because of the risk
of cable damages! There are only to use flexible cables, e.g
H05VV-F for high voltage power cables, and e.g. LIYY for sensor
cables.
6.5.2
Cable lengths
Bus/sensor lines do not have mains voltage, but safety extra-low voltage.
They must not be routed in parallel to the mains cables (interference
signals). Otherwise shielded cables must be installed.
Pipe length permitted:
Cu-cable up to 20 m: 0.8 mm
2
Cu-cable up to 80 m: 1 mm
2
Cu-cable up to 120m: 1.5 mm
2
Cable types : e.g. LIYY or LiYCY 2 x 0.8
6.5.3
Strain reliefs
All the cables should be fixed in the strain relief clamp of the control panel
and connected according to the connection diagram.
For more information, see
6.5.4
Replacing cables
All connecting cables, except for the mains connection cable, have to be
replaced by Potterton Commercial special cables in case of replacement.
When replacing the mains connection cable, only cables of the types
H05VV-F 3 x 1 mm
2
or 3 x 1,5 mm
2
have to be used.
