Connect Pressure Line; Connecting The Power Supply - Honeywell EK205-M Operating Instructions Manual

Installation, connection and commissioning

6.2.4 Connect pressure line

When connecting the pressure lines, national requirements must be observed.
For Germany, the requirements of the PTB inspection rules, volume 20 Electronic
Volume Conversion Devices for gas, section 5 apply.
When installing pipelines, ensure that there is a downward gradient from the EK205-
M to the gas line.

6.2.5 Connecting the power supply

DANGER!
The connection of non-associated equipment presents a risk of explosion!
Operating the EK205 in zone 2 and connecting devices which are not certified as
"associated equipment" present a risk of explosion.
Therefore:
– When using the EK205 in zone 2, it should only be connected to certified
associated equipment as per the ATEX Product Directive 94/9/EC.
– The EK205-M should only be connected to the intrinsically-safe circuits of
associated equipment whose electrical data correspond to those requirements
stipulated in the declaration of conformity for the EK205-M (see Appendix).
For the external power supply of the EK205-M (model without in-built power supply unit), the
electrical data should be adhered to as per sections 13.3 and 4.2.3.
The extended function unit "FE260" from Elster can be used as a power supply unit, for example.
Connect the power supply in safe assembly area only. Modem power needs to be
unplugged and removed from the enclosure to access the power connections in the
field.
