is powered from the a.c. mains supply via an IEC 320 connector. The electrical ratings of the
unit are as follows:
100 – 240 V ac +10%, -15% 47 – 63 Hz 650 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. The
protective earth contact shall not be negated by the use of an extension cable without protective
conductor.
An earth stud (M5 thread) is provided to allow bonding of the CMM metal parts to the protective earth.
WARNING: Any interruption of the protective conductor may make the equipment dangerous.
Make sure that the grounding requirements are strictly observed.

The following environmental conditions comply with (or exceed) BS EN 61010-1:1993
Indoor use IP20 (no protection against water)*
Altitude up to 2000 m
Operating temperature 0 °C to +50 °C (local to SPA 2 )
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 Installation category II
