mains voltage.
They must comply with the applicable regulations.
• Only the screw-type terminals in the separated area on the

Calibrated device!
• The device must be protected by an external overcurrent
protective device (max. 10A) so that the unit shuts down sa-
fely in the event of an electrical fault.
The power supply must be designed to ensure that it has
adequate protection against intentional interruption and that
it can be shut down for maintenance.
• A marked 2-pole isolating device is mandatory. Alternatively,
a 2-pole isolating overcurrent protective device can be used.
However, it must not be possible to the circuit for the totaliser
to be disconnected independently of the heating or cooling
system.
• The connection cable must have a temperature resistance
> 65°C.
