• Instruments mounted in explosion hazardous areas must not be opened when the
power is on. Tighten the cable gland firmly.
• The maintenance and repair of the instrument is limited to fulfill the explosion
proof regulations.
• Ensure that all personnel are suitably qualified.
• Observe the specifications in the certificate as well as national and local regulations.
2.3.2 Power supply

technical data of the instrument before turning on the power, in Chapter 12, Technical
data.
2.3.3 Grounding
Do not remove the grounding of the instrument when the power supply is turned on.
This may set the instrument in a dangerous condition.

2.4 Return
The following procedures must be carried out before the instruments is sent to Varec

• Always enclose a duly completed "Declaration of Contamination" form. Only then
can Varec transport, examine and repair a returned device.
• Enclose special handling instructions if necessary, for example, safety data sheet as
per EN 91/155/EEC.
• Remove all residue which may be present. Pay special attention to the gasket
grooves and crevices where fluid may be present. This is especially important if the
fluid is dangerous to health, e.g. corrosive, poisonous, carcinogenic, radioactive,
etc.
A copy of the “Declaration of Contamination” is included at the end of this operating
manual in Appendix B.
Caution! No instrument should be sent back for repair without all dangerous material being
completely removed first, e.g. in scratches or diffused through plastic.
• Incomplete cleaning of the instrument may result in waste disposal or cause harm
to personnel (burns, etc.). Any costs arising from this will be charged to the
operator of the instrument.
