4.5.1 Regulations for electrical connections
All electrical installation work, in particular implemen-
tation of protective measures, must be performed in
accordance with the pertinent laws and any specific re-
gulations imposed by the local energy company; local re-
quirements must be observed in particular.
During assembly of the system, the requirements of VDE
0100 and the regulations imposed by the responsible
energy company must be complied with.
Accident prevention regulations
«General regulations (VBG1)»
«Electrical installations and equipment (VBG4)»
Electrical connections must be established in accordance
with the electrical connection diagram enclosed with the
boiler. The electrical connection diagram does not include
protective measures. The appropriate protective measu-
res must be implemented during installation of the system
and when connecting the unit in accordance with VDE
0100 and the regulations of the local energy company.
The boiler is only to be installed in rooms corresponding
to the protection class of the appliance (IP20). To prevent
induction voltages, low voltage and power current cables
(230 V~) must be routed separately at a distance of at
least 10 cm. Where low voltage and power current cables
have to be installed in cable ducts, these are to be kept
apart by a separator.
4.5.2 Electrical connection (mains) 230 V, 50 Hz
The boiler is wired ready for connection. It is fitted with a
connector cable of approx. 1.5 m length with main con-
nector plug. A socket is to be installed directly adjacent
to the boiler (maximum 1m from the edge of the casing).
The fusing is to be selected so that the limits detailed in
the Technical Data are never exceeded.
Non compliance with this regulation can have serious
consequences for the controller in the event of a short
circuit.
When working on the gas boiler the appliance is to be
disconnected from the electrical supply!
The applicable accident prevention regulations and the
generally recognised rules of the art are to be complied
with for the electrical installation and commissioning.
WARNING
Automatic firing units are safety devices and
are not to be opened.
4.5.3 Boiler control / electrical connection diagram
The electrical connection is to be executed correspon-
ding to the electrical connection diagram in the boiler.

4.5.4.1 TopTronic
®
E
The TopGas
®
(80) is delivered as standard with a
TopTronic
®
E controller for external mounting. Your Hoval
agent will provide you with a detailed description of the
scope of supply.
4.5.4.2 TopTronic
®
E
As an option the TopGas
®
(80) can be equipped with a
TopTronic
®
E - controller incorporated in the appliance.
Your Hoval agent will provide you with a detailed descrip-
tion of the power outputs of this type of controller. The
installation of the TopTronic
®
E-ZE1-is described in a se-
parate instruction.
- TopTronic
®
E
In principle the TopTronic
®
E controller (H-Gen) permits
weather-supported flexible heating operation of two re-
gulated mixer circuits, a direct circuit plus the hot water
provision with an indirectly heated water heater (e.g.
Hoval CombiVal). A possible hydraulic system is de-
tailed under 4.3.6. Control possibilities are expandable
with key-modules.
