OUNDATION
Fieldbus protocol
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.
a. If you do not seal unused connections, mount the indicator
with the electrical housing positioned downward for drainage.
b. Install wiring with a drip loop.
c. Arrange the drip loop so the bottom is lower than the conduit
connections and the indicator housing.
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.
