In this case, the plant operator or the person using the device should check
whether the device may be connected, where appropriate by discussing the mat-

An electric shock can be fatal. Every electric shock is potentially life threatening.
To avoid electric shocks while using the charger:

All cables and leads must be secured, undamaged, insulated and adequately di-
mensioned. Loose connections, scorched, damaged or inadequately dimensioned
cables and leads must be immediately repaired by authorised personnel.

Safety measures
Chargers with a ground conductor must only be operated on a mains supply with
in normal opera-
a ground conductor and a socket with a ground conductor contact. If the charger
tion
is operated on a mains supply without a ground conductor or in a socket without
a ground conductor contact, this will be deemed gross negligence. The manufac-
turer shall not be held liable for any damage arising from such usage.
Only operate the charger in accordance with the degree of protection shown on
the rating plate.
Under no circumstances operate the charger if there is any evidence of damage.
Arrange for the mains cable to be checked regularly by a qualified electrician to
ensure the ground conductor is functioning properly.
Any safety devices and parts that are not functioning properly or are in imperfect
condition must be repaired by a qualified technician before switching on the
charger.
Never bypass or disable protection devices.
