Notes: 
1. Maximum continuous output power with Chassis and Cover option is 20 W. 
2. Maximum operating ambient is 50 °C. 
3. Maximum operating Relative Humidity 96 %, no condensation. 
4. Storage: -40 to +85 °C. Units should be allowed to warm-up under non-condensing conditions before application of 
power.
CERTIFICATION: All models are Certified to be in compliance with the applicable requirements of 
UL 2601-1 2

Edition, CSA 22.2 No. 601.1-M90, IEC 601-1 (1988)/EN 60601-1: 1990 +A1 +A2
CLASSIFICATION:
(5.1)
Protection against electric shock = Class I
(In accordance with sub-
(5.2)
Degree of protection against electric shock = Signal output or intermediate
clause 5 of IEC 601-1)
(5.3)
Protection against harmful ingress of water = Ordinary (no protection)
(5.5)
Have not been evaluated for use in the presence of a flammable anaesthetic
mixture with air, oxygen, or nitrous oxide. This evaluation is to be made on the 
end equipment by the OEM. 
(5.6)
Mode of operation = Continuous
GROUNDING: The Functional Earth terminal must be bonded to Protective Earth in the host 
equipment. Using the Functional Earth terminal on the supply for the grounding the host equipment is 
not recommended. A separate dedicated grounding point should be used. 
OUTPUTS: All output commons should be connected to Protective Earth in the end application. The 
output(s) are intended for Protectively Earthed Signal Output and Intermediate Circuits only. The 
output(s) are not acceptable for patient connection without additional isolation. All DC outputs are 
SELV under normal and single fault conditions. 
OVERVOLTAGE PROTECTION:  Only output #1 is monitored for an overvoltage condition. The 
trip-point for a 5 volt output is 5.6 to 6.8 volts. In some applications where an overvoltage condition 
could result in a hazard as defined in applicable safety standards, redundant or additional overvoltage 
protection may be required. Consult factory for details. 
CAUTION: When performing Dielectric Strength Tests, catastrophic failure of the unit may result if a 
Dielectric Strength test voltage greater than 1800 V ac is applied between primary and secondary 
circuits. The components providing isolation from primary to secondary cannot be tested while installed 
in the power supply without overstressing basic (primary to ground) insulation. All isolating 
components are individually 100 % tested at 4800 V ac prior to installation.
