Special Instructions for medical applications (IEC 60601-1:1988 + A1:1991 + A2:1995; EN 60601-1: 1990 +
A1:1993 + A2:1995; UL 60601-1, 1st Edition, 2006-04-26 (includes National Differences for USA) CAN/CSA-
C22.2 No. 601.1-M90 (R2005) (includes National Differences for Canada); IEC 60601-1:2005; EN 60601-1:2006;
ANSI/AAMI ES 60601-1:2005; CSA 22.2 No 60601-1:2008) - Applicable to products with L, R and T Input
Filter Options only
These products are designed for continuous operation within an overall enclosure, and must be mounted such that
access to the mains terminals is restricted.
These products are NOT suitable for use in the presence of flammable anaesthetic mixtures with air or with oxygen,
or with nitrous oxide.
For IEC60601-1, EN60601-1 and UL/CSA 60601-1 (Second Edition standards), the Alpha 1000 range provides
Basic insulation between input and outputs, and functional insulation between outputs and earth.
For IEC 60601-1:2005; EN 60601-1:2006; ANSI/AAMI ES 60601-1:2005; CSA 22.2 No 60601-1:2008), the Alpha
1000 range provides reinforced insulation between input and outputs (2 MOOPs) for all products. Between outputs
and earth there is functional insulation only.
Connect only apparatus complying with the standards listed above as appropriate to the signal ports.
These products are classed as ordinary equipment and are not protected against the ingress of water (IPX0).
Reference should be made to local regulations concerning the disposal of these products at the end of their useful
life.
Where any part of this product is made accessible to the operator in the end use equipment, the operator must not
touch this part and the patient at the same time.
These products have not been assessed to IEC/EN60601-1-2 (EMC) but EMC test data is available from TDK-
Lambda UK Ltd.
WARNING: No modification of this product is allowed.
Except for permanently installed equipment, the overall equipment into which these products are installed must have
double pole fusing on the input mains supply. The products themselves have single pole fusing in the live line only.

Level of Insulation:
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 500VDC.
*This test is not possible with modules fitted to the unit as damage to RFI capacitors will occur)
