Appendix A. CE Mark Compliance

A.1 Introduction
For CE Mark compliance, the Model GF868 flowmeter must be wired in accordance with the instructions in this
appendix.
CE Mark compliance is required only for units intended for use in EC countries.
IMPORTANT:
A.2 Wiring
The Model GF868 must be wired with the recommended cable, and all connections must be properly shielded and
grounded. Refer to Table 10 for the specific requirements.
Connection

Transducer
Armored RG62 a/u or conduit
22 AWG shielded (e.g. Baystate #78-1197)
Input/Output
Armored conduit
14 AWG, 3 conductor, shielded (e.g. Belden
#19364)
Power
Armored Conduit
For CE compliance, power and I/O cables must be shielded. Cables to be terminated within cable

gland at the GF868. Shielded cable is not required when installations include metal conduit.
A.3 External Grounding
For CE Mark compliance, the electronics enclosure and the transducer fixture must each have an external ground wire
attached.
Note: If the Model GF868 is wired as described in this appendix, the unit will comply with the EMC Directive
2004/108/EC.
