Special Instructions for medical applications (IEC/EN/UL/CSA 60601-1)
These products are designed for continuous operation within an overall enclosure, and must be mounted
such that access to the mains terminals is restricted. See clause 16, IEC60601-1, EN60601-1 and UL/CSA
60601-1.
These products are NOT suitable for use in the presence of flammable anaesthetic mixtures with air or with
oxygen, or with nitrous oxide.
These products are classed as ordinary equipment, type B and have a Reinforced barrier between input and
output to IEC60601-1, EN60601-1 and UL/CSA 60601-1. They are NOT protected against the ingress of
water.
All outputs have basic spacings to earth rated for mains - 250Vac, and due consideration must be given to
this in the end product design.
Reference should be made to local regulations concerning the disposal of these products at the end of their
useful life.

Dielectric Strength testing is carried out as follows:
Primary mains circuit to earth: - 2.25 - 2.35kVDC
Primary mains circuits to transformer core: - 4.25 - 4.35kVDC*
Primary mains circuits to secondary: -4.25 - 4.35kVDC*
Outputs to each other and to earth are isolated to XXXVDC.
*This test is not possible with Y capacitors fitted to the unit as damage to these
capacitors will occur. It is also necessary to short circuit the outputs together and to earth.
