3.5.5. Electrical hazards
WARNING
Risk of electric shock!
Electrical hazards due to people coming into direct contact with live parts. Parts
likely to present an electrical hazard must be positioned or protected in such a way
that they cannot be touched by personnel.
There is a risk of fatal electric shock from live parts! Even when the main switch is
switched off, electrical voltage is present at the power supply terminals in the control
cabinet of the CHP plant. Before working on the plant, the power supply must be switched
off and secured against being switched on again.
The electrical installation is only allowed to be carried out by a specialist electrician trained
by Hoval.
WARNING
Risk of electric shock!
Electrostatic discharge when touching the machine: The plant and machine parts must be
earthed so that potential differences can be compensated.

General safety instructions
Specialist personnel
Installation, commissioning, maintenance and repairs to the CHP plant are only allowed to
be carried out by qualified installers.
Maintenance
The CHP plant must be serviced and inspected at the prescribed intervals. Documentation
(maintenance book) must be kept for this purpose. If the documentation is not kept,
any warranty claims will lapse.
Covers
Behind the covers which can only be removed with auxiliary means (keys, tools), there are
components which if touched can lead to injuries (hot and/or live parts). These covers are
only allowed to be removed by specialist personnel.
Seals
It is forbidden to destroy seals. If the seals are destroyed or opened, the manufacturer's
warranty will be invalidated.
Frost protection
The heating system must be protected from frost. This is only guaranteed if the CHP plant
always remains in operation. If the plant is switched off, the manufacturer does not
assume any warranty for frost damage.
Operating parameters
The operating instructions must be read carefully before any parameters on the CHP plant
are modified. Unauthorised modification of the type-related nominal output is prohibited.
