1.3 User safety
All regulations, codes, and health and safety directives must be ob-
served.
The site
• Observe lockout/tagout procedures before starting work on the
product, such as transportation, installation, maintenance, or serv-
ice.
• Pay attention to the risks presented by gas and vapors in the work
area.
• Always be aware of the area surrounding the equipment, and any
hazards posed by the site or nearby equipment.
Qualified personnel
This product must be installed, operated, and maintained by qualified
personnel only.
Protective equipment and safety devices
• Use personal protective equipment as needed. Examples of person-
al protective equipment include, but are not limited to, hard hats,
safety goggles, protective gloves and shoes, and breathing equip-
ment.
• Make sure that all safety features on the product are functioning
and in use at all times when the unit is being operated.
1.4 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 po-
tentially 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 inter-
national and national standards (for example, IEC/EN 60079-17).
Xylem disclaims all responsibility for work done by untrained and unau-
thorized personnel.
Product and product handling requirements
These are the product and product handling requirements for Ex-ap-
proved 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 permit-
ted 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.
• Intrinsically safe circuits are normally required for the automatic lev-
el-control system by the level regulator if mounted in zone 0.
• The yield stress of fasteners must be in accordance with the appro-
val drawing and the product specification.
• Do not modify the equipment without approval from an Ex-ap-
proved Xylem representative.
• Only use original Xylem spare parts that are provided by an Ex-ap-
proved Xylem representative.
• The thermal detectors that are fitted to the stator windings must be
connected correctly to a separate motor control circuit and in use.
The detectors disconnect the power supply to the motor timely.
This action prevents the rise of temperatures above the tempera-
ture value for the approval classification.
