230 VAC
This PCB module is galvanically separated from the mains supply and is
suitable for direct 230 V mains installation. The module includes a double-
chamber safety transformer, which fulfils double insulation requirements
when the cover is mounted on Pulse Transmitter/Pulse Divider. Power
consumption is less than 1 W or 1 VA.
National regulations for electric installations must be observed. The 230
VAC module can be connected/disconnected by the district heating
station’s personnel, whereas the fixed 230 V installation in the meter
panel must be carried out by an authorized electrician.

24 VAC
This PCB module is galvanically separated from the 24 VAC mains supply
and is both suitable for industrial installations with joint 24 VAC supply and
individual installations, which are supplied by a separate 230/24 V safety
transformer in the main electrical panel. The module includes a double-
chamber safety transformer, which fulfils double insulation requirements
when the cover is mounted on Pulse Transmitter/Pulse Divider. Power
consumption is less than 1 W or 1 VA.
National regulations for electric installations must be observed. The 24
VAC module can be connected/disconnected by the district heating
station’s personnel, whereas the fixed 230/24 V installation in the main
electrical panel must be carried out by an authorized electrician.
Note: This module cannot be supplied by 24 VDC (direct current).

230/24 VAC safety transformer
The 24 VAC module is especially suited for installation together with a
230/24 VAC safety transformer, e.g. type 6699-403, which can be installed
in the main electrical panel before the safety relay. When the transformer
is used, the total power consumption of the meter incl. the 230/24 VAC
transformer will not exceed 1.7 W.
