Electrical requirements

The UCC2 is powered from the a.c. mains supply via an IEC 320 connector. The operating voltages of the unit are as follows:

100 - 120 V ac and 220 - 240 V ac –15%, +10% 50/60 Hz ±5% 120 W maximum

This equipment must be connected to a protective earth conductor via a three core mains (line) cable. The mains plug shall be inserted only into a socket outlet provided with a protective earth contact. Do not use an extension cable without a protective conductor.

An earth stud is provided to allow bonding of the CMM’s metal parts to the protective earth.

CAUTION: Any interruption of the protective conductor may make the equipment dangerous. Make sure that the grounding requirements are strictly observed. 

Environmental requirements

The following environmental conditions comply with (or exceed) BS EN 61010-1:1993

Indoor use

IP30 (no protection against water)


up to 2000 m

Operating temperature

0 °C to +50 °C

Storage temperature

-10 °C to +70 °C

Relative humidity

80% maximum (non-condensing) for temperatures up to +31 °C Linear decrease to 50% at +40 °C

Transient overvoltages
