Install the bolts and washers, and attach the nuts. Tighten the bolts in a star–
patterned sequence to equalize compression. Unless otherwise specified, use a
torque specification of 50 foot pounds.
For 1 inch, NPT bushing configurations, simply thread the bushing into the
corresponding opening on the tank. To adapt to a flange mounting, simply use a
tapped flange that will accept the 1 inch NPT bushing.
Installation Wiring
Basic wiring consists of
• connecting power to the gauge (24 Vdc standard, 100-240 Vac future
option), and
• setting up serial communications with the gauge.
Additional wiring can include
• relay contacts,
• contact switch inputs, and
• 4-20 mA current outputs.
Caution: Remove all power from the unit before making any
connections.
Warning: All wiring must be done by qualified individuals in
accordance with NEC (National Electric Code) ANSI/NFPA 70
specifications, or the Canadian Electrical Code, Part I.
If metal conduit is used, it must be grounded.
Instructions
You will need a 1/8 inch bladed screwdriver to connect the wires to the plug-in
connector. Refer to Wiring Diagram 868641 for wiring details.
