1 Cable
2 Shield
3 Instrument
It is vitally important to ensure the shielding is pinched and secured between the two washers to ensure the
shielding attaches directly to the instrument housing as a ground. Failure to do this could cause damage to
the instrument, and for sensor cables give incorrect readings.
5. Reattach and tighten the cable gland nut.
6. Attach the wires to the corresponding terminal block connections.
4.6 Connection to mains power supply
4.6.1 Power supply connection (low voltage instruments)
For low voltage instruments (10-30 VDC), connection to the mains power supply is with a 8-pin
BINDER connector (supplied).
Note: The connectors are grooved to avoid an incorrect fitting to the instrument.
Connect the power cable to the connector as follows:

Multiple hazards. Only qualified personnel must conduct the tasks described in this section of the
document.
Electrocution hazard. Always remove power to the instrument before making electrical connections.
High voltage instruments (100-240 VAC) have a 4-pin male connector pre-wired internally with a
male BINDER connector ready for mains connection. A compatible female connector is supplied with
the instrument.
