1. Introduction
1.1 General Introduction
DC UPS is the innovative power protection solution for delicate network devices and
telecom equipments. It equips with 12V/30Watts power capacity and internal long 7
amp-hour backup battery. With universal input voltage design, this UPS can be widely
applied to the majority power system without AC input voltage transfer. The advantages of
DC output are saving the cost and space of the additional power adapter connection. This
feature further prevents the power loss while transferring between DC to AC. The thoughtful
wall-mount design allows you to install DC UPS to diverse environments for maximizing
your precious space. DC UPS can be applied to any other device equipped with a
compatible DC input connector.
Features
Universal input range (80-260VAC) for global applications
12VDC (30W max.) output meets the major standard of network devices
Integrated hot-swappable to easy replacement battery allows battery replacement
without power interruption.
Microprocessor controlled for optimized operation and maximum reliability
Audible warning alarm with mute switch
Outputs for remote monitoring; On Battery, Replace Battery, Battery missing and
Low battery alert
Wall mountable design for maximized flexibility
Multiple LED for AC power and battery status indications
Cold Start function capable

2. Safety Information
Internal battery voltage is 12V DC.
Incorrect battery connection or replacement creates risk of explosion. Use only vender
approved replacement batteries.
The DC UPS is intended for installation and operation in a controlled environment
(temperature controlled, indoor area free of conductive contaminants). Refer to
specifications in this manual.
No user-serviceable parts exist inside the unit. Refer repair issues only to qualified
personnel. Fuses or other parts must be replaced ONLY with parts of identical types
and ratings. Substitution of non-identical parts can cause fire and other safety hazards.
All batteries used are sealed lead batteries. Batteries should be recycled.
The battery charges when it is connected to the AC power. The battery will fully charge
during the first eight hours of normal operation. Do not expect full battery run capability
during this initial charge period.
Connect the DC UPS to utility power for completely charging the internal battery before
starting the UPS.

4. Installation
4.1 Wire Connection
1. Remove the wire connection cover in the rear of the DC UPS. Keep the cover will and
reinstall the cover after all the wires are well-connected.
2. Plug IEC-LOCAL power cord into theAC input socket on the back of DC UPS. Do not
connect the AC power cord to utility outlet prior to this process.
3. Connect DC UPS to network device.
3.1 If the telemetry cable is enclosed:
(1) Plug the telemetry cable into the 7-position connector
(2) Then place the cable between the two sticks for fixing the cable as the following
picture

8
3.2 If the telemetry cable is not enclosed:
(1) Cut and strip the self-prepared cable leads, and then attach the leads to the
7-position connector. Make sure that the correct wire gauges are used for the
safety (Please refer to “1.3 The 7 Pin Terminal Connecter Intro Table”)
(2) Plug the 7-conductor cable into the outlet of the DC UPS
(3)Then place the cable between the two sticks for fixing the cable as the following
picture
4. Close the wire connection cover
5. Connect the other end of the cable to the equipment

4.2 Wall-Mounting Instructions (Optional)
NOTE: Required hardware not included. Refer to the wall-mount instructions for required
tools and materials.
STEP 1: Make a mark on the wall in the 2 screw locations. The distance between the
centers of the 2 screws are 80cm.
STEP 2: Use a drill to drill holes where you made the mark on the wall. If you drill into a wall
stud, proceed to Step 5. If not, go to Step 4.
STEP 3: Insert anchor(s) into the hole(s).
STEP 4: Screw in the screw, leaving it protruding 1⁄4 inch from the wall.
STEP 5: Mount the DC UPS on the screw heads. Mounting holes

5. Operation
After the installation, you can start to operate the DC UPS and let your device running
under uninterruptible power supply environment as the following procedure.
STEP 1: Plug the AC input power cord of the DC UPS into the wall outlet (The utility power
outlet)
STEP 2: Push the power on/off switch and you may hear a long beep buzzer alarm for
knowing the unit is properly turned on. You may turn the audible alarm off by pushing the
mute switch button to ON (Push down) position.
Self-test
Use the self-test to verify both the operation of the DC UPS and the condition of the battery.
Turn the mute switch ON then OFF, then ON and OFF again within five seconds. During the
Self-test, the DC UPS operates in backup mode.
The DC UPS automatically conducts a Self-test in two conditions. 1) Operate it and then the
MCU detects battery voltage is higher than 13V. 2) Every 21 days while operating all the
time.
Note: During the self-test, the DC UPS briefly operates on battery-backup power. The
green LED will flash for five minutes during the test period. If the DC UPS passes the
Self-test, it returns to online operation. If the DC UPS fails the Self-test, it immediately
returns to online operation and lights the red LED. The loads are not affected. Recharge the
battery overnight and perform the self-test again. If the red LED is still on, the battery needs
to be replaced.

7. Battery Replacement Procedure
The DC UPS is designed with an easy-access battery cover.
STEP 1 Turn off power switch. Disconnect the DC UPS from power and any connected
devices. Remove the battery door on the front of the DC UPS by pulling up the battery door.
STEP 2 Remove the battery from enclosure; remove the wire connections from the battery.
STEP 3 Connect the new battery (black-to-black, red-to-red); place the battery into the
enclosure, and then put the wires next by the battery inside of the closure as shown bellow.
WARNING: Connect the correct color wires carefully to the corresponding terminals. The
battery has two color-coded terminals (red = +, black = -) as well as the two colors of the
wires. Misconnect the two wires to wrong terminals might cause battery explosion.
