Power supply connection (high voltage instruments)
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.
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.
User-supplied power cable specifications:
• 3-wire (live, neutral and earth)
• cable Ø ≥ 7mm; ≤ 9.5mm
• wire selection ≥ 1mm
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:
1. Take the narrow end of the connector (4) in one hand and the main body (2) in the other and
unscrew the two. Pull away the cable clamp (3) and unscrew the end plug (1) to reveal the four
parts that make up the connector.
2. Loosen the screws on the cable clamp (3) to allow enough room to pass the power cable through.
