*1. Output power is less than 50W for 5V model and 70W for 12V~48V models.
General installation instructions
1) CUS100MB is for installation in Class I end equipment only, and therefore must be reliably earthed and professionally
installed.
CUS100MB/G2 is optional model for installation in Class II end equipment, and no earthing connection to the power
supply is required.
2) These products are IPX0, and therefore chemicals/solvents, cleaning agents and other liquids must not be used.
3) The first protective earth connection in the final installation must be marked with the protective earth symbol.
Special Instructions for IEC/UL/ 60601-1
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, IEC/UL60601-1.
2) These products are NOT suitable for use in the presence of flammable anaesthetic mixtures with air or with oxygen or with nitrous oxide.
3) These products are classed as ordinary equipment according to IEC/UL60601-1 and are NOT protected against the ingress of water.
4) Reference should be made to local regulations concerning the disposal of these products at out of their useful life.
5) These products have not been assessed to IEC/UL60601-1-2 (EMC) but EMC test data is available from TDK-Lambda Corporation.
6) For Class II installation (CUS100MB/G2), the product needs to be fixed such that they are isolated from unearthed accessible conductive parts
by at least 2 MOPP’s.
7) For IEC/EN 60601-1 2nd Edition, UL 60601-1 1st Edition, CSA-C22.2 No. 601.1-M90, these products have a reinforced insulation barrier
between input and output. For IEC/EN 60601-1 3rd Edition, ANSI/AAMI ES 60601-1, CSA 22.2 No 60601-1, these products provide
reinforced insulation between input and outputs of 2 MOPPs. 1 MOPP from input to earth and 1 MOPP from output to earth.
8) All outputs have basic spacing’s to earth rated for mains - 250Vac, and due consideration must be given to this in the end product design.
9) These products have SELV outputs.
