4.1 Precautions
Before starting work, make sure that the safety instructions have been read and understood.
DANGER: Electrical Hazard
Before starting work on the unit, make sure that the unit and the control panel are isolated
from the power supply and cannot be energized. This applies to the control circuit as well.
DANGER: Explosion/Fire Hazard
Special rules apply to installations in explosive or flammable atmospheres. Do not install the
product or any auxiliary equipment in an explosive zone unless it is rated explosion-proof or
intrinsically-safe. If the product is rated explosion-proof or intrinsically-safe, then see the
specific explosion-proof information in the safety chapter before taking any further actions.
DANGER: Inhalation Hazard
Before entering the work area, make sure that the atmosphere contains sufficient oxygen
and no toxic gases.
Before installing the pump, do the following:
• Provide a suitable barrier around the work area, for example, a guard rail.
• Make sure that equipment is in place so that the unit cannot roll or fall over during the
installation process.
• Check the explosion risk before you weld or use electric hand tools.
• Check that the cable and cable entry have not been damaged during transport.
• Always remove all debris and waste material from the sump before you install the pump.
