This equipment is designed to operate at 230V AC 50/60Hz mains supplies, class 1 construction. As such it must
be connected to a protective earthing conductor in the fixed wiring of the installation and a readily accessible double
pole disconnect device meeting the requirements of EN60950/IEC950 which disconnects live and neutral simulta-
neously shall be incorporated in the fixed wiring.
Switch disconnect devices such as MK Sentry 63A or similar are suitable for this. Failure to ensure that all conduc-
tive accessible parts of this equipment are adequately bonded to the protective earth will render the equipment un-
safe.
This Control Panel is environmental class A and is designed for indoor use only at temperatures between -10°C and
+45°C with a maximum relative humidity of 95%. The IP rating for the enclosure is IP30.
Operation outside of these limits may render the equipment unsafe.
