Product and product handling requirements
These are the product and product handling requirements for Ex-approved products in potentially explo-
sive 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 authorized ITT representative.
•
Only use parts that are provided by an authorized ITT representative.
1.2.4.1 Description of ATEX
The ATEX directives are a specification enforced in Europe for electrical and non-electrical equipment
installed in Europe. ATEX deals with the control of potentially explosive atmospheres and the standards
of equipment and protective systems used within these atmospheres. The relevance of the ATEX re-
quirements is not limited to Europe. You can apply these guidelines to equipment installed in any poten-
tially explosive atmosphere.
1.2.4.2 Guidelines for compliance
Compliance is fulfilled only when you operate the unit within its intended use. Do not change the condi-
tions of the service without the approval of an ITT representative. When you install or maintain explosion
proof products, always comply with the directive and applicable standards (for example, IEC/EN 60079–
14).
1.2.5 Monitoring equipment
For additional safety, use condition-monitoring devices. Condition-monitoring devices include but are not
limited to these devices:
•
Pressure gauges
•
Flow meters
•
Level indicators
•
Motor load readings
•
Temperature detectors
•
Bearing monitors
•
Leak detectors
•
PumpSmart control system
•
Filter
