ELECTRICAL INSTALLATION
6.1.2
Suitable power supply
Risk of electrical shock!
The output circuit of the power supply must be safely electrically isolated from the input
circuit. This feature is normally provided by a safety transformer in accordance with IEC
742 (VDE 0551).
Use a safety transformer to generate the supply voltage.
For information on the supply voltage for the Bulkscan and the heating (see "11 Techni-

Lay the data cable separately from the power supply and motor cables, e.g., in sepa-
rate cable channels, to prevent interference.
6.2
Carrying out the electrical installation on the Bulkscan
Risk of tripping due to cables! Risk of damage to the cables!
Exposed cables on the floor in areas used by people can pose a risk.
Lay all cables so that there is no risk of tripping and all cables are protected against
damage.
Risk of reduced enclosure rating!
Only connect and mount, if necessary, the electrical connections in a dry and clean
environment.
Only use round connectors that are compliant with enclosure rating IP 67.
