Safety Information
To prevent damage or injury, only trained personnel may operate the product.
Please observe the following:
• When installing or removing a power supply module, please wear an
ESD-preventive wrist strap, and make sure that it has good skin contact
and is well grounded.
• Before installing a power supply module, ensure the external power supply
system voltage matches the module’s rated input, and the module’s output
voltage matches the device requirements to avoid damage.
• Do not touch any exposed wires or terminals to avoid bodily injury.
• Do not place the power module in a humid place or allow the liquid into the
power supply module.
• If there is a failure inside the module, please contact service personnel
instead of opening the housing of the module.
• The equipment must not be used in locations where children are likely to be
present.
• Plug the product into a wall outlet with an earthing connection through the
power supply cord.
• The socket-outlet must be installed near the equipment and shall be easily
accessible.
Install the Power Supply Module
1. Wear an ESD-preventive wrist strap and make sure that it has good skin
contact and is well grounded.
2. With one hand, press the Release Handle on the right side of the power
supply module inward. With the other hand, support the bottom of the
module and gently slide it into the slot along the guide rail.
3. Release the Release Handle to x the power supply module in place.
Connect the Power Cord and Connect to the Ground
1. Plug the female connector of the provided power cord into the power socket
of the device and the male connector into a power outlet. Meanwhile, keep it
connected to the ground via the power supply.
2. Conrm that the power supply LED is green.
Release Handle
Remove the Power Supply Module
If you need to remove the power supply module, please follow these steps:
1. Turn o the power at its source.
2. Wear an ESD-preventive wrist strap and make sure that it has good skin contact
and is well grounded.
3. Remove the power cord from the external power supply system and the power
module.
4. With one hand, press the Release Handle on the right side of the power supply
module inward. With the other hand, slide the power supply out.
Caution:
When installing or removing a power supply module, pay attention to the
following:
• Make sure that the power supply module is set correctly when installing.
• Do not force the power supply module into the slot. If resistance is
encountered or positions of the power supply module appear larger during
installation, you must rst remove the module and then reinstall the module.
• If the Retainer Clips cannot spring up and the power module is blocked, the
module may be improperly installed. Please check carefully.
• To better protect the power supply module during removal, it is recommend-
ed that you package it in an antistatic bag.
(Optional) Install the Locking Latch
The power supply module is designed with a locking latch slot.
If you need to secure the power cable with the included locking latch, please
follow these steps:
1. Wear an ESD-preventive wrist strap and make sure that it has good skin
contact and is well grounded.
2. Remove the instruction label on the locking latch slot.
3. Secure the strap in the power cord retainer by inserting it into the slot near
the power supply module to hold the clamp in place.
4. Slide the clamp around the AC power cord and press the tabs on the clamp
towards each other to secure the AC power cord.
5. Adjust the distance of the locking latch using clips to ensure the cable
is securely fastened.
