Warning.

Observe all local instructions and regulations governing electrical installation. Ensure the power
supply and / or bus connections are switched off before making connections.



Ensure connection to protective earth.

Do not apply power until fully installed.

The transmitter is not fitted with a switch and does not have an overvoltage protection device,
lightning protection or voltage separation capacity therefore these must be provided on the plant
side.

Power supplies and signals are routed in the same line and must be implemented as SELV or
PELV circuits according to requirements (standard version). In the ignition-proof version, the
guidelines regarding the ignition-proof requirements must be adhered to.

4.1 Cable Glands and Plugs

4.1.1 APA592–PH for Intrinsically Safe, Type n and Non-incendive Installations
Non-Ex d transmitters are supplied with a nylon conduit plug and cable gland. The cable gland is sized to
provide a tight seal around the sensor cable.
If a customer-supplied cable gland and plug is used, the cable diameter for the cable gland used must
comply with the requirements for IP/NEMA 4X protection. This must be checked during installation.
4.1.2 APA592–PH Ex d / Explosion-proof Models without Cable Gland
APA592–PH Ex d / explosion-proof rated transmitters are supplied with a standard 316 stainless steel rated
plug.
Hazardous area 316 stainless steel
based on the hazardous area installation requirements.
Note. For ATEX installations, an approved ATEX Ex d cable gland must be used according to
IEC/EN 60079-1. For FM and CSA installations, an approved Ex d cable gland must be used.
