The reciprocating pumps must not be installed
in Zone 0 (containers).
GROUNDING
In hazardous locations, the appliances must be earthed.
In accordance with the directive on "Static Electricity" ZH 1/200, the following applies:
The grounding connection must be mechanically resistant and corrosion-proof to withstand all
conditions to which it may be subjected during operation. The conductors which establish the
grounding should be connected to appliances and the earth by soldering, welding or stable screw
fittings. Do not use chains. When making connections, in particular to pipelines, ensure that the
conductor is not interrupted by non-conductive parts or during repair work
The grounding connection must be tested for correct working conditions by an authorised engineer.
Grounding points on the appliances are appropriately marked:
Movable, conducting vessels or appliances, which could store an electric charge should also be
earthed. The is usually achieved with a flexible connection that is secured, for example, with a clip.
- Chains may not be used.
VENTILATION OF WORK AREA
Must be ensured
AIR PRESSURE SUPPLY
The compressor and air pressure storage container (pressure tank) must have adequate
dimensions.
- Check
