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.
• You must fully submerge the Ex-approved product 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.
• Some gap and diametrical clearances could be less than the values specified in table
1 in the standard EN 60079-1. Contact Xylem for any maintenance on flameproof
joints.
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).
Minimum permitted liquid level
See the dimensional drawings of the product for the minimum permitted liquid level
according to the approval for explosion proof products. If the information is missing on
the dimensional drawing, the product must be fully submerged. Level-sensing equipment
must be installed if the product can be operated at less than the minimum submersion
depth.
