1 Basic information

Electronic equipment is not fault proof. This fact should be borne in mind for all
possible operating conditions.

ATTENTION - High voltageAC 500V~, DC 650V=
500V~ac, 650V=dc

Before installation or commissioning begins, this manual must be thoroughly
read and understood by the technical staff involved.
If any uncertainty arises, the manufacturer or dealer should be contacted.
Q3 devices are power electric parts used for regulating energy flow.
Protection rating IP00.

Standards and guidelines

The device and its associated components can only be installed and switched on
where the local regulations and technical standards have been strictly adhered
to:
EU Guidelines 89/392/EWG, 84/528/EWG, 86/663/EWG,
72/23/EWG
