CUI INTERNAL POWER SUPPLIES MANUAL
This user manual applies to all CUI internal ac-dc power supplies.
CUI internal ac-dc power supplies are intended to be installed inside of the
system chassis and will have pins, connectors, or terminals for connecting to
the ac input power source and dc output load. The supplies are available in
different versions which may be mounted on a PCB, chassis, or DIN rail. The
enclosure of the power supplies may be open frame, U-frame, closed frame (with
or without fan) or encapsulated.
GENERAL USE
Verify the output voltage, current, and polarity of the power supplies match
that required by the load.
Verify proper dc output power cables or PCB traces are correctly connected to
the output of the power supplies.
- Verify the load is correctly connected to the dc output cables or PCB traces Verify proper ac input power cables or PCB traces are correctly connected to the input of the power supplies.
- Verify the ac input safety ground (FG) is connected, if applicable Connect the ac input to the correct power source. Allow adequate spacing and ventilation so the power supplies do not overheat.
- Do not use the power supplies in ambient temperatures beyond those specified in the datasheet
- Do not cover or obstruct ventilation holes or openings during use Disconnect the ac power source when the system is being serviced or not being used.
WARNINGS
Risk of electric shock, fire, or energy hazards.
- Power supplies may not have shielding to prevent contact with dangerous voltages during use
- Power supplies may not have shielding to prevent contact with hot surfaces during use
- Power supplies that are damaged or not working properly should be replaced
- There are no user-serviceable parts inside of the power supplies
- Contact your local qualified recyclers for disposal of CUI power supplies
- Power supplies should not be used near open heat sources
- Power supplies should not be exposed to liquids or damp environments CUI internal power supplies comply with EMI and EMC regulations as specified in the datasheet.
INSTRUCTIONS
DIN rail mounting
- DIN rail supplies must be mounted vertically with the input terminals down
- To fasten the supply to the rail hold the supplies so the bottom is slightly away from the rail and the top is slightly forward
- Set the top of the latch over the top of the rail
- Pull the supplies down firmly
- Press the bottom of the supplies against the rail to latch onto the rail
- Wiggle the supplies to ensure they are properly latched on the rail
Additional application and safety information can be found on the CUI website and datasheets.
