An electric shock is potentially life threatening and can be fatal.
Do not touch live parts either inside or outside the device.
All cables and leads must be secured, undamaged, insulated and adequately
dimensioned. Loose connections, scorched, damaged or inadequately dimen-
sioned cables and leads must be replaced immediately.
Do not sling cables or leads around the body or parts of the body.
Only switch on the device when all output connections have been established
correctly.
The device must only be operated on a mains supply with a ground conductor
and a socket with a ground conductor contact.
If the device is operated on a mains supply without a ground conductor, this
will be deemed as gross negligence. The manufacturer shall not be held liable
for any damage arising from such usage.
Arrange for the mains cable to be checked regularly by a qualified electrician
to ensure the ground conductor is functioning properly.
Switch off unused devices.
Disconnect the mains plug before working on the device.
Attach a clearly legible and easy-to-understand warning sign to the device to
prevent anyone from plugging the mains plug back in and switching it on
again.
After opening the device:
- Discharge all live components
- Ensure that all components in the device are de-energised.
If work on live parts is required, appoint a second person to switch off the main
switch at the right moment.
The housing screws provide an adequate ground conductor connection for
earthing the housing. The screws must never be replaced with different
screws unless a reliable ground conductor connection is set up.
Devices in emission class A:
- Are only designed for use in industrial settings
- Can cause line-bound and radiated interference in other areas
Devices in emission class B:
- Satisfy the emissions criteria for residential and industrial areas.
This is also true for residential areas in which the energy is sup-
plied from the public low-voltage mains.
