HAZARDOUS LOCATION INSTALLATIONS

For hazardous location installations, refer to the SmartLine Guided Wave Radar Level
Transmitter User's Guide, Document #34-SL-23-11 for further information and
warnings.

Explosion-proof conduit seal

When installed as explosion-proof in a hazardous location, keep covers tight
while the transmitter is energized. Disconnect power to the transmitter in the
non-hazardous area prior to removing end caps for service.
When installed as non-incendive or non-sparking equipment in a hazardous
location, disconnect power to the transmitter in the non-hazardous area, or
determine that the location is non-hazardous before disconnecting or
connecting the transmitter wires.

US Installations

Transmitters installed as explosion proof in Class I, Division 1, Group A Hazardous
(classified) locations in accordance with ANSI/NFPA 70, the US National Electrical
Code, with ½ "conduits, do not require an explosion-proof seal for installation.
Conduits with a ¾" conduit, require a LISTED explosion-proof seal installed in the
conduit. The seal must be installed –SL-within 18" (457.2 mm) of the transmitter.

SET THE JUMPERS FOR HART

The SmartLine Level Transmitter (HART) provides two jumpers to set the desired
failsafe action and Write Protect option. See
Top Jumper
Sets the Failsafe direction.
Default: Up-scale Failsafe
Up-scale drives the loop to a value
greater than 21 mA.
Note: Down-scale faults are
always latching.
