Mains connec-
tion Devices with a higher rating may affect the energy quality of the mains due to
their current consumption.
This may affect a number device types in terms of:
- Connection restrictions
-
Criteria with regard to the maximum permissible mains impedance
*)
-
Criteria with regard to the minimum short-circuit power requirement
*)
*)
at the interface with the public grid
see "Technical data"
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-
ter with the power supply company.
IMPORTANT! Ensure that the mains connection is earthed properly
Protecting your-
self and others
For your personal safety, take the following precautions:
Use suitable protective clothing
Protective clothing refers to a variety of different items. Operators should:
- protect their eyes with the specified protective goggles;
- wear stout footwear that provides insulation even in wet conditions;
- protect their hands by wearing suitable gloves (electrically insulated, heat-
proof, protection from cut injuries);
- wear ear protection to reduce the harmful effects of noise and to prevent in-
jury.
Keep all persons, especially children, out of the working area while any devices
are in operation or calibration is in progress. If, however, there are people in the
vicinity,
- warn them of all the dangers
- provide suitable protective equipment or
- erect suitable safety screens/curtains
Risks from mains
current and
welding current
An electric shock is potentially life threatening and can be fatal.
Do not touch live parts either inside or outside the device.
Make sure that you and others are protected with an adequately insulated, dry
base or cover for the earth or ground potential. This base or cover must extend
over the entire area between the body and the earth or ground potential.
All cables and leads must be secured, undamaged, insulated and adequately di-
mensioned. Replace loose connections and scorched, damaged or inadequately
dimensioned cables and leads immediately.
Use the handle to ensure the power connections are tight before every use.
In the case of power cables with a bayonet connector, rotate the power cable
around the longitudinal axis by at least 180° and pre-load.
Do not wrap cables or leads around the body or parts of the body.
Arrange for the mains cable to be checked regularly by a qualified electrician to
ensure the ground conductor is functioning properly.
