2.3.3 Levelling
The VRS-20 needs to be parallel to the water surface for reliable and consistent operation. To aid this, the
sensor has been fitted with two bubble levels. Once the clamp or mounting bracket is firmly fixed to the
mounting surface the two-axis adjustment on the bracket can be adjusted until the VRS-20 is level.
2.3.4 Wiring
The VRS-20 is supplied as standard with a 5m cable (Other lengths are available on request). The cable is
glanded into the VRS-20 at the sensor end, and issued as unterminated cable at the other end. This is to
allow easy routing of the cable through walls/bulkheads etc.
2.3.4.1 Junction box
The cable from the VRS-20 sensor terminates into a small junction box.

The bare cable from the VRS-20 should be passed through
the cable gland and terminated in the push fit connectors with
reference to the wiring schedule.
To insert the bare wires into the terminals, push in the orange
tab in with a fine screwdriver and release to clamp the wire.
The output from the junction box will depend on the
configuration of the VRS-20. Refer to section
