Ex-approved products

Follow these special handling instructions if you have an Ex-approved unit.

Personnel requirements

These are the personnel requirements for Ex-approved products in potentially explosive
atmospheres:

• All work on the product must be carried out by certified electricians and Xylem

authorized mechanics. Special rules apply to installations in explosive atmospheres.

• All users must know about the risks of electric current and the chemical and physical

characteristics of the gas, the vapor, or both present in hazardous areas.

• Any maintenance for Ex-approved products must conform to international and national

standards (for example, IEC/EN 60079-17).

Xylem disclaims all responsibility for work done by untrained and unauthorized personnel.

Product and product handling requirements

These are the product and product handling requirements for Ex-approved products in
potentially explosive atmospheres:

• Only use the product in accordance with the approved motor data.
• The Ex-approved product must never run dry during normal operation. Dry running

during service and inspection is only permitted outside the classified area.

• Before you start work on the product, make sure that the product and the control panel

are isolated from the power supply and the control circuit, so they cannot be
energized.

• Do not open the product while it is energized or in an explosive gas atmosphere.
• Make sure that thermal contacts are connected to a protection circuit according to the

approval classification of the product, and that they are in use.

• Intrinsically safe circuits are normally required for the automatic level-control system by

the level regulator if mounted in zone 0.

• The yield stress of fasteners must be in accordance with the approval drawing and the

product specification.

• Do not modify the equipment without approval from an Ex-approved Xylem

representative.

• Only use parts that are provided by an Ex-approved Xylem representative.

Guidelines for compliance

Compliance is fulfilled only when you operate the unit within its intended use. Do not
change the conditions of the service without the approval of an Ex-approved Xylem
representative. When you install or maintain explosion proof products, always comply with
the directive and applicable standards (for example, IEC/EN 60079–14).
