NOTE: For ambient temperatures under 40 °C the maximum output power for the SPA3 is 800 W. For temperatures between 40 °C and 50 °C the maximum power is 400 W.

WARNING: SPA3 is not recommended for use in ambient temperatures above 50 °C.
WARNING: Earthing provisions for the complete machine is the responsibility of the OEM or installer.
WARNING: SPA3 is isolated from the power supply by disconnection of the ac power connector from the external PSU. 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 isolator must be sited within easy reach of the CMM operator and comply with IEC61010 and any applicable national wiring regulations for the country of installation.
WARNING: The PSU must be single fault tolerant, approved to EN60950-1 and must be connected to a supply incorporating a protective earth conductor. Earthing provisions and residual fault protection for the complete machine is the responsibility of the OEM or installer.

Machine safety

WARNING: Switching off or isolating the SPA3 may NOT prevent unexpected machine movement. The user is advised to isolate the machine from the electricity supply, compressed air or other energy sources in accordance with the machine manufacturer's instructions before entering the danger zone or performing any maintenance operations.

If the equipment is used in a manner not specified by the manufacturer, the protection provided by the equipment may be impaired.

The emergency stop safety system that has been integrated into the SPA3 is designed to achieve category 2 to standard BS EN ISO13849-1:2008. This can be hardware configured to obtain category B. The risk assessment made by the system installer on the installation should therefore have determined which category is required.

CAUTION: It is strongly recommended that the CMM manufacturer or retrofitter includes a periodic test of the emergency stop and if fitted, the associated reset switch in their maintenance instructions.

The SPA3 must only be commissioned through Renishaw software. Failure to do so may result in unexpected machine movement.
