Aenons
For all series of UPS, they are strictly tested and carefully designed. We always do our best to make our products
more reliable and safer; this is also the goal of our company. However, due to the lifeme of electrical components
and some unpredictable reasons, there will be unavoidable failures of this UPS. If this situaon occurs, service of
qualied person is needed. This service manual will guide the technicians to repair and adjust a problemac UPS.
If the UPS sll does not work properly, please contact with us and we will be glad to solve any problems you met.
Because of the following unique features of this series UPS (Uninterrupble Power System), it is very easy to main-
tain and service.
* All major power components are put on POWER PCB.
* POWER PCB and CONTROL PCB are interconnected with connectors.
* Major parts are simply connected with exible insulated wires and plugs.
This service manual consists of 4 major parts:
• Introducon.
• Principle of operaon: It describes the funcons and principles of each part.
• Alignments: It describes the locaons and methods needed to adjust this UPS.
• Trouble shoong: This part describes the possible failure condions and procedures to repair it.
Before starng to serve this UPS, be sure to read this manual carefully for a correct and safe operaon.
Important Safety Instrucons
1. For qualied service personnel only.
2. DO NOT perform any internal service or adjustment of this product unless another person is capable of render-
ing rst aid and resuscitaon is present.
3. Dangerous voltage exists at several points in this product. To avoid personal injury, don’t touch any exposed
connecons or components while UPS is acve.
4. Turn o the UPS and disconnect input power cord before removing outside protecve cover.
5. AC voltage is always present if the input AC power is sll available.
6. High voltage may present at DC capacitors. Before opening the outside cover, wait for at least ve minutes
aer turning o the UPS.
7. Verify input source (voltage and frequency) before service.
1. DO NOT make internal baeries short-circuited.
2. If the baery connectors are disconnected, be sure to plug in the input power cord and the input power is
available before re-connect the baery connectors.
3. Aer service, verify the polarity of baeries, the ghtness of all screws and connectors before restarng the
UPS.
Aer opening the cover, please always check the ghtness of all wires, connectors and screws rst. Then check if
there are any de-colored components inside.
