5. Environmental Parameters
6. C.E. Marking
Designed to comply with EN60950-A4, CSA C22.2 No.234-M90, CSA-C22.2 No.950-95 and UL1950-95 when correctly installed in a
limited access environment.
The SC Series of products is designed for the following parameters: Material group llla, Pollution Degree 2, Installation Category 2,
class 1, indoor use (as part of any other equipment such that the SC Series product is accessible to service engineers only).
Humidity: 5 to 95% RH non-condensing, Operational Temperature 0 to 50
STORAGE/TEMPERATURE: Temperature –40
Approval Limitations - Use in North America
When this product is used on 180-250VAC mains with no neutral, connect the two live wires to L (live) and N (neutral) terminals on the
input connector. In this instance double pole fusing is required.
Level of Insulation
Dielectric Strength testing is carried out as follows: Primary AC circuit to earth – 2.4kVDC; **Primary mains circuits to secondary
>4.3kVDC. (**This test is not possible as a finished product as damage to “Y” capacitors will occur.)
CE marking when applied to a product covered by this handbook indicates compliance with the Low Voltage Directive (73/23/EEC) as
modified by the CE Marking Directive (93/68/EEC) in that it complies with EN60950.
