Safety Cautions
To reduce the risk of bodily injury, electrical shock, fire and damage to the product, observe the following
precautions.
Do not service any product except as explained in your system documentation.
Opening or removing covers may expose you to electrical shock.
Only a trained service technician should service components inside these compartments.
If any of the following conditions occur, unplug the product from the electrical outlet and replace the part
or contact your trained service provider:
 The power cable, extension cable, or plug is damaged.
 An object has fallen into the product.
 The product has been exposed to water.
 The product has been dropped or damaged.
 The product does not operate correctly when you follow the operating instructions.
Do not push any objects into the openings of your system. Doing so can cause fire or electric shock by
shorting out interior components.
Make sure that there is proper heat dissipation from and adequate ventilation around the power supply.

Mounting the Power
Desktop Mounting
The power supply can be mounted on a desktop or shelf. Make sure that there is proper heat dissipation from
and adequate ventilation around the power. Do not place heavy objects on the power.
19” Rack Mounting
Two 19-inch rack mounting brackets are supplied in the power package for 19-inch rack mounting.
The steps to mount the power onto a 19-inch rack are:
1. Turn the AC power off.
2. Install left and right brackets with supplied screws onto the power as shown in figure below.
3. Mount the power onto 19-inch rack with rack screws securely.
4. Turn the power to the switch on.
-11-
Wall Mounting
The product also supports wall mounting by installing optional wall-mount brackets as shown below:
Consult the agent where the product was purchased for the wall-mount brackets.
-12-
Applying Power
Applying AC Power Input
If the purchased product is with AC power input, one AC power cord which meets the specification of your
country of origin was supplied in package. Before installing AC power cord to the product, make sure the AC
power is OFF and the AC power to the power cord is turned off.
AC power input specifications
Connector: IEC320 type
Power Rating: 100 ~ 240VAC, 50/60Hz
Notice
An approved AC power supply cord should be used and not lighter than IEC 60227, H03VV-F, 3G, 0.75mm2 or
alternatively IEC 60245, H05RR-F, 3G, 0.75mm2.
