Power Isolation Transformer for External Devices

IOLMaster Warning Symbol   Warning
Always connect all peripheral devices, printers and monitors to the power isolation transformer.

No components other than those prescribed for the system may be connected to the power isolation transformer or instrument table. Noncompliance represents a violation of the regulations for use of medical devices under DIN EN 60601-1-1.

Likewise excepted are laser printers, as their rated supply voltage usually exceeds the permissible connected load of the power isolation transformer. Position the laser printer outside the patient’s range (1.5 m from the patient’s seat at the device).

If the Carl Zeiss IT 3L instrument table is used, the power isolation transformer may be mounted to the underside of the tabletop. It may be secured elsewhere, but not placed on the floor.

IOLMaster Warning Symbol   Warning
The IOLMaster should never be operated via the power isolation transformer!

The power isolation transformer is not a constituent part of the IOLMaster.
