Auxiliary supply
10.4.1
Input voltage 230 VAC (type no.: HC-993-13)
This module is galvanically separated from the 230 VAC supply and is used for supplying either analog output
modules or passive 24 V flow sensors from a third-party supplier, see more in paragraph 8.4. The module is
constructed as a Switch Mode Power Supply that meets the requirements for double-insulation when the calculator
top is mounted on the calculator base. There is space for one of this type of module in MULTICAL® 803 in the 230
VAC version. The module provides 24 VDC voltage to the connection terminals 97A on the connection board 6699-
045 as well as to the two connectors for the supply of analog output modules placed above the connection terminals
on the connection board.
If connected to 230 VAC the whole installation must fulfil current national regulations. Connection/disconnection of
the module must be carried out by the meter installer. However, note that work on fixed installations and in the
electrical panels must be carried out by an authorized electrician.
10.4.2
Input voltage 24 VAC/VDC (type no.: HC-993-14)
This module is galvanically separated from the 24 VAC/VDC supply and is used for supplying either analog output
modules or passive 24 V flow sensors from third-party suppliers, see more in paragraph 8.4. The module is
constructed as a Switch Mode Power Supply that meets the requirements for double-insulation when the calculator
top is mounted on the calculator base. There is space for one of this type of module in MULTICAL® 803 in the 24
VAC/VDC version. The module provides 24 VDC voltage to the terminals 97A on connection board 6699-045 as well
as to the two connectors for the supply of analog output modules placed above the connection terminals on the
connection board.
The whole installation must fulfil current national regulations. Connection/disconnection of the module must be
carried out by the meter installer, whereas installation of the 230/24 VAC safety transformer in electrical panels as
well as other fixed installations must be carried out by an authorized electrician.
