DANGER
Danger due to electrical voltage!

The entire electrical wiring must be voltage-free.
CAUTION
Observe additional information!

Before commissioning, compare the conformity of the supply voltage with the information on the nameplate.

Provide a suitable switch or circuit breaker in the building installation. This switch must be installed near the
device (easily accessible) and marked as a disconnecting device.

An overcurrent protection device (rated current ≤ 10 A) is required for the mains cable.
5.3 Wiring
Overview of the connections:
For installing the heat meter and the associated subassemblies, the general regulations,
according to EN1434-Part 6, must be observed.
