Safety instructions for electrical systems
DANGER
High voltage!
Danger to life!
Under no circumstances should you touch the HV wires or HV connections without ensuring that
there is no voltage beforehand!
The device may only be connected by a qualified electrician!
Under no circumstances should you bypass or avoid security installations! Any malfunctions resulting
from this could have life threatening consequences!
Always use an insulation monitoring unit for ongoing monitoring of the galvanic isolation between HV
and LV circuits!
Before starting work with the device, the shut-down of the coupled motors must be ensured! Even
when the HV supply is switched off, a turning motor can still produce voltage!
INSTRUCTION
Under no circumstances should the device be opened without authorisation! The opening of the
device (housing sealed-up) leads directly to the forfeit of any guarantee and warranty rights!
INFORMATION
Adhere strictly to the following 5 safety rules when working on a HV grid:
Disconnect system from power.
Switch off the ignition
Remove service / maintenance plug and/or turn off main battery switch
Remove fuse
Ensure that system does not reconnect.
Keep ignition key safe to prevent unauthorised access.
Keep service / maintenance plug safe to prevent unauthorised access.
Use lockable cover cap to ensure that the main battery switch does not reconnect.
Check that it is not live with a suitable voltage tester (note voltage range!)
Ground and short-circuit the system.
Cover or seal-off adjacent live parts.
