1. Remove the housing cover on terminal compartment side.
Note
Do not remove the cover in explosive atmospheres when the circuit is
live. Signal wiring supplies all power to the indicator.
2. Connect the power leads to the terminals marked "FIELDBUS WIRING"
as shown in
Note
The power terminals are not polarity sensitive.
3. Plug and seal unused conduit connections on the indicator housing to
avoid moisture accumulation in the terminal side.
Note
Do not apply high voltage (e.g. ac line voltage) to the indicator terminals.
Abnormally high voltage can damage the unit. Indicator terminals are rated to
32 Vdc.
