Safety instructions for electrical systems
DANGER
High voltage!
Danger to life!
Do not touch the HV wires or connections without ensuring the absence of voltage beforehand!
The PDU may only be connected by a qualified electrician!
Safety installations must not be by-passed or avoided! Any resulting malfunctions could have life
threatening consequences!
Before carrying out any work on the PDU, make sure that the coupled motor has come to a
complete standstill! Even when the HV supply is switched off, a turning motor can still produce
voltage!
INFORMATION
When working on a HV grid, the following 5 safety rules have to be strictly adhered to:
Disconnect the system from the voltage supply.
Switch off the ignition.
Remove service / maintenance plug and/or turn off main battery switch.
Remove fuse (external fuse box).
Ensure that the system does not reconnect.
Keep ignition key safe to prevent unauthorised access.
Keep the service / maintenance plug safe to prevent unauthorised access and/or
use lockable cover cap to ensure that the main battery switch does not reconnect.
Ensure that the device is de-energised by means of a suitable voltage tester (note voltage
range!)
Earth and short-circuit the system.
Cover or seal off adjacent live parts.
