2.7  Installation of Explosion Protected Type Transmitters

In this section, further requirements and differences and for explosion 
protected type instrument are described. For explosion protected type 
instrument, the description in this chapter is prior to other description in this 
user’s manual.

CAUTION

To preserve the safety of explosion protected type instrument requires 
great care during mounting, wiring.
Safety requirements also place restrictions on maintenance and repair
activities. Please read the following sections very carefully.

2.7.1  ATEX Certification

See Appendix.1 ATEX Installation drawing YTA70PQA01

2.7.2  FM Certification

See Appendix.2 FM Installation drawing YTA70PQF01

2.7.3  IECEx Certification

See Appendix.3 IECEx Installation drawing YTA70PQI01

2.7.4  CSA Certification

See Appendix.4 CSA Installation drawing YTA70PQC01

2.7.5  Label of Explosion Protected Type

See Appendix.5 Label of Explosion Protected Type

NOTE

The YTA70P is a single sensor input model.
Please ignore the loop construction of CH2.
