5.4 Electrical installation
The documentation does not cover the installation of the voltage supply. Requirements
regarding it are covered, however.
CAUTION: The layout of the electrical installation as well as the layout of the voltage supply have
to comply with the local safety regulations and standards.
NOTES on the electrical installation
It is obligatory to run the connecting cables through the cable fittings provided for that purpose
in the device.
CAUTION: The atomisers may only be supplied with 48Vac, 50..60Hz.
5.4.1 BS5/10
The voltage supply for the atomisers BS5/10 is supplied directly to the wall brackets (with a junction
box) via the external safety transformer (see also page 25).
CAUTION: Before and when working on the devices, make sure that all lines are de-energised
and that the voltage supply is secured against unintentional switching on.
NOTE: The transformer ought to be positioned as close as possible to the atomisers in order to
avoid an unnecessary loss of voltage on the lines. You can connect max. 4 atomisers to the
supplying transformer.
A special plug is included in the scope of delivery of the wall brackets. Only this plug may be used to
connect the atomisers.
