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.
Connection to mains power supply
Power supply connection (low voltage instruments)
For low voltage instruments (10-30 VDC), connection to the mains power supply is with a 7-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:

Pin Connections:
1. Not used
2. Power 10-30 VDC
3. Not used

5. Ground
6. Not used
7. Earth
Power supply connection (high voltage instruments)
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.
If this female connector was supplied with a mains power plug already pre-attached (cable part
numbers 33031, 33032, 33033 and 33034) then the female connector can be plugged directly into
the instrument power connector. The two connectors are grooved to avoid an incorrect fitting. Tighten
the female connector to the instrument power connector finger-tight.
If no power cable was ordered with the equipment, a mains power plug must be connected to the
supplied female connector as described in the following procedure.

Personal Injury Hazard. Only qualified personnel should conduct the tasks described in this section of the manual.
User-supplied power cable specifications:
3-wire (live, neutral and earth)
cable Ø ≥ 7mm; ≤ 9.5mm
wire selection ≥ 1mm

Potential Electrocution Hazard. Always disconnect power to the instrument when making electrical connections.
Prepare the user-supplied power cable as follows:
1. Strip off 23 mm (0.9 ins.) of shielding from the power cable.
2. Cut back the live and neutral wires to 15 mm (0.6 ins.) in length but leave the earth wire as is.
3. Then strip off a small amount of external insulation from the three wires as required.
Wire the female connector as follows:
