2.1.9 Installation Checklist

Prior to operation, it is important to do the following checks.

∙Ensure transmitter and sensor are properly and firmly mounted.

∙Ensure that the enclosure certified stopping plug is tightened to unused conduit entry/opening, to maintain ingress protection and flameproof type protection.

∙Ensure transmitter and sensor are not being obstructed; transmitter and sensor are accessible and target gas is not inhibited from reaching sensor.

∙Remove sensor red protective plastic cap.

∙If hydrophobic filters (IPF-001) are being used, check for damage or debris. See the IP 66/67filter Instruction guide (MAN-0109) for instructions.

∙If calibration cups (splash guards) are fitted to sensor, ensure a snug fit.

∙Ensure adherence to applicable local guidelines and requirements on wiring and sealing of equipment in hazardous and non-hazardous areas.

∙Ensure that proper shielding and grounding practices are adhered to, and local codes are being followed.

∙Check system operational voltage and conditions. See Table 1 and Appendix C.

∙Check wiring at all termination and junction points; wiring at transmitter terminals, junction box and at power supply. Refer to Table 1, also Figure 7, Figure 8, Figure 9, Figure 12 and Figure 13
