Safety
The recommended operating procedures have been designed with careful attention to safety. Severn
Trent Services has made formal safety reviews of the initial design and any subsequent changes. This
procedure is followed for all new products and covers areas in addition to those included in applicable
safety standards. Regardless of these efforts, it is not possible to eliminate all hazards from the test
equipment or to foresee every possible hazard that may occur. It is therefore essential that the user, in
addition to following the safety rules in this manual, also carefully consider all safety aspects of the test
before proceeding. Safety is the responsibility of the user.
This equipment has been designed in accordance with safety specifications IEC 1010-1 and ANSI/ISA
S82.01 and meets the requirements for Class I, Installation Category II equipment.
Observe the following safety precautions:
Observe all safety warnings marked on the equipment. These warnings identify areas of
immediate hazard, which could result in personal injury, or loss of life.
Do not use this equipment for any purpose other than described in this manual.
Disconnect power to the Cl1000B prior to making any terminal connections within the monitor
enclosure.
Do not operate the equipment with the electronics enclosure open for an extended period of time.
Operation without the protective instrument covers presents an electric shock hazard.
Use all practical safety precautions to prevent contact with energized parts of the equipment and
related circuits.
Use the recommended connection procedures described in Section 2 of this manual.
The Cl1000B Residual Analyser operates from a single-phase power source. A three-wire power cord is
required for power connection. The voltage to ground from either pole of the power source must not
exceed the maximum rated operating voltage, 240 VAC. Before making connection to the power source,
determine that the voltage of the power source is correct. The power source must have a fuse or circuit
breaker, recommended rating: 2 Amp anti surge MCB.
Severn Trent Services recommends that qualified personnel install and connect the instrument.
Component replacement and internal adjustments must be made by qualified service personnel only.
