The SPA

is isolated by disconnecting the IEC mains connector on the rear panel. If any additional
means of isolation is required, it must be specified and fitted by the machine manufacturer or the installer
of the product.
The SPA
2
is powered from the a.c. mains supply via this IEC 320 connector. The electrical requirements
of the unit are as follows:
100 – 240 V ac +10%, -15% 47 – 63 Hz 650 W maximum
The SPA 2 is isolated from AC power by disconnection of the IEC mains connector on the rear panel. If
any additional means of isolation is required, it must be specified and fitted by the machine manufacturer
or the installer of the product.
The use of a suitable RCD (residual current device), for automatic disconnection in the event of an
insulation failure, is recommended. This should be sited within easy reach of the CMM operator and must
meet the requirements of IEC61010 and any national wiring regulations in the country of installation.
