GLS55, GLS55-M Installation & Operating Instructions
To comply with the published safety standards, the following must be observed when using this
power supply:
1. Maximum ambient temperature for the power supply must not exceed 50°C. The power
supply has been evaluated for use in 70°C at half load (30 W) for GLS55 only.
2. When installing the power supply in the end-use equipment, special attention is required
to ensure safety compliance with the following safety standards: UL60950-1, EN60950-1,
IEC60950-1, and CSA22.2 No. 60950-1-03 for GLS55; UL60601-1, EN60601-1,
IEC60601-1, and CSA22.2 No. 60601-1-M90 for GLS55-M. The safety requirements include
creepage distances, clearances, and distance through insulation between primary wiring and
earth or secondary (SELV) wiring.
3. This power supply is approved and certied for the rated voltage range of 100 V ac to 240 V ac.
4. The maximum output power of the supply must not exceed the rating indicated in the speci-
cation sheet.
5. The disconnection from the line must be in the end system.
6. The internal fuse should only be replaced with a T3.15AH, 250 V ac, type TE5/392 manufactured by Wickmann.
NOTE: The power supply has a fuse on the neutral line for GLS55-M.
7. GLS55-M has no patient applied part.
8. This equipment is considered Class I according to protection against electric shock.
9. This power supply is
2006/95/EC.
