Installation Procedures:

The STEELCAGE assembly can be lowered and placed directly on the floor of
the wet well/lift station. No stilling well is necessary. The cable should be routed
into the logger or control panel for connection. The assembly does not need to be
suspended; it can be placed directly on the wet well floor. The cable should be
snug with minimal slack to prevent the assembly from “traveling” about in any
turbulence in the wet well. Any excess cable can be coiled with a tie wrap and
hung on the wall. This will work fine as long as there is no sharp bend in the
cable that could cause it to kink.

DO NOT kink the cable, as this will cause blockage to the breather tube inside.

Electrical Installation:

There are two wires, a vent tube and ground inside the cable.

TURN OFF POWER BEFORE CONNECTING THE WIRES!

1. Connect the ground wire first (shield to earth ground to appropriate
controller ground).

2. Then connect the red wire to a 13-30 VDC (24 VDC nominal) power
supply. Note: An external power supply with a minimum current capability of
40 mA per transmitter, is required.

3. Connect the black lead to the 4-20mA input on the logger or other
equipment that will be monitoring the sensor.
