Are mains and DC cables as well as the control cables installed separately from each other?
Are all mass and earthing cables attached and well contacted?

Remove any tools from the control cabinet!
Attach all covers and protective caps to ensure that all live parts are secured against direct contact.
When using measuring instruments or computers an isolating transformer should be used, if not, make
sure that the equipotential bonding between the supply lines is guaranteed!
Open the control release of the COMBIVERT to avoid the unintended starting of the machine.

4.1.4 Safety Instructions
General instructions
Electric
Shock
COMBIVERT R6 power supply und regenerative units contain dangerous voltages which
can cause death or serious injury.
COMBIVERT R6 can be adjusted by way that energy is regenerated into the supply system
in case of power failure at regenerative operation. Therefore a dangerous high tension can
be in the unit after switching off the supply system.
Before working with the unit check the isolation from supply by measurements in the
unit.
Care should be taken to ensure correct and safe operation to minimise risk to personnel
and equipment.
