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.
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; including the requirements for creepage
distances, clearances, and distance through insulation between primary wiring and earth or
secondary (SELV) wiring.
3. The power supply’s rated input voltage is automatically selected. Please refer to the specifi
-
cation sheet for the input voltage range.
4. The maximum output power of the supply must not exceed the rating indicated in the specifi
-
cation sheet.
5. The earth ground wire must be connected only to the point marked with the earth ground
symbol (on the unit).
6. The disconnection from the line must be in the end system.
7. Hazardous voltages exist in the primary circuits. Disconnect the power supply before
servicing.
8. The unit must be protected by a fuse in the end system. Components, such as capacitors, may
be positioned in front of the internal fuse.
9. When operating with a dc input voltage range, the dc source must be rectified from a mains
supply not exceeding 250 V ac. The unit input must also be protected by a dc rated fuse in
the end-use installation system.
10. The internal fuse should only be replaced with a F6.3AH, 250 V ac, type 21606.3 manufac-
tured by Littelfuse, type 50CF063H manufactured by Triad, or type S501 manufactured by
Cooper.
11. This equipment is considered Class I according to protection against electric shock.
12. This power supply is
marked following the provisions of the Low Voltage Directive,
2006/95/EC.
