ı. GENERAL DESRCIPTION
1.1 Introduction
Messages displayed on the front panel are subject to change depending on the developments in UPSs. But
the Axx codes in front of the alarm messages are always the same. To be informed by the latest
developments in software. Please contact the service center.
1.1.1 Cautions for service personal
High voltage exists inside the UPS. Touching such points is very dangerous and hazardous. Accidental
electric arcs can be very hazardous while working inside the UPS (Only trained personal).
Some electrical components are heavy. If replacement is required please use suitable and helpful apparatus.
Otherwise injuries may occur.
Energy storage devices such as batteries and capacitors are used in the UPS. Before maintenance turn off
the device and wait at least 3 minutes to completely discharge the capacitors. Make sure batteries are
disconnected.
Unfortunate accidents may occur, therefore we advise a second helping service element nearby.
Take of any metal objects such as rings ot bracelets that can make a short circuit.
1.1.2 Battery cautions
Ni Cd batteries are used in the UPS’s. If not so, then the type of the batteries is lead acid. Therefore, use
protecting wear or hand gloves while maintaining batteries. Keep a fire extinguisher nearby the batteries
against any probable fire due to arcs.
Batteries are polluting elements. Therefore, be careful when disposing.

F3-F4-F5 : Rectifier input switch – Input switch & fuse
MBS : Maintenance By Pass switch.
F6 : Output switch & fuses
•F1-F0 – Battery circuit breaker switch & fuse
Located at the input side of the device. It protects the other side of the system against any faults may occur
on the battery or the device.
•F2 – ON – OFF switch & fuse
F2 is basically a fuse on the bypass input line and it has an integrated micro switch which is used for turning
ON and OFF the UPS. Therefore, F2 will be mentioned as ON – OFF switch.
•F3-F4-F5 – Rectifier input fuse (switch)
These switches connect the line input to the input of the rectifier/charger. All power supplies in the equipment
connected to this switch.
•MBS – Mechanical maintenance bypass switch
There is no fuse on the line of mechanical by pass.
When the UPS is faulty or during the maintenance period this switch is used to connect the load, directly to
the bypass line.
•F6 – Output switch & fuses
This switch connects the output of the UPS to the load. This switch must be turne
d OFF after the
maintenance bypass switch is turned on properly according to its procedure. Maintenance bypass line is
connected to the output of this switch.
General description of UPS parts:
RECTIFIER/CHARGER: The first conversion stage (from AC to DC) uses a 3 phase, 6 pulse, fully controlled
rectifier to convert the incoming mains supply into a regulated DC BUS BAR. The DC BUS BAR produced by
the rectifier provides both battery charging power and power to the inverter section.
BATTERY GROUP: It keeps as an reserve DC power supply, for the inverter in case of mains failure.
Note : To increase the lifetime of the batteries keep them in room temperature (20
o
C-25
o
C).
INVERTER: It is made by utilizing the latest technology of power transistor (IGBT) and pulse width
modulation (PWM). Inverter converts dc bus voltage into (second conversion) an alternative voltage like line
voltage. And provides this voltage and frequency being fixed.
STATIC TRANSFER SWITCH (STATIC BY-PASS): The circuit block annotated contains an electronically
controlled switching circuit, which enables the critical load to be connected either to inverter output or to a by-
pass power source via the” static by-pass line”.
MECHANIC TRANSFER SWITCH (MAINTENANCE BY-PASS): Manually controlled, ”maintenance by-pass”
supply is also incorporated into the UPS design. Its purpose is to enable the critical load to be powered from
the mains (by-pass) supply while the UPS is shut down for maintenance or troubleshooting.

2.3 STATUS Messages
This message group simply shows the UPS STATUS at the upper line of LCD PANEL.
RECTIFIER START ! : UPS started the rectifier
ENTER START : Press ENTER to start the UPS.
INVERTER START ! : UPS started the inverter.
MAINT SWITCH ON ! : Maintenance bypass switch is on
STATUS NORMAL ! : UPS is operating.
EMERGENCY STOP ! : External emergency stop signal is applied to UPS.
WAITING SYNC ! : Inverter started waiting for mains synchronization.
STATUS FAULT ! : Fault status
RECTIFIER START :
At start up the UPS controller board checks for input voltage, frequency, battery voltage for starting ,if these
parameters normal, UPS starts.
INVERTER START :
If the inverter stops from any reason, controller board tries to start inverter again, during inverter start this
message appears on first line of LCD PANEL
MAINT SWITCH ON:
Maintenance bypass switch is connected from input to the output of UPS directly .Đf the maintenance bypass
switch is on (1 position) controller stops inverter for accidental short circuits between mains voltage and
inverter output. If the user turn off maintenance switch inverter starts again.
EMERGENCY STOP :
If an external EPO switch is installed to system (connected to interface board), to stop all UPS parts (rectifier,
static bypass ,inverter ,etc….) is possible . After pressing EPO switch all parts of the UPS stops, for restart
turn off S1 (inverter input) switch and turn on again.
FAULT STATUS :
In some cases controller checks events but can not find solutions, in this case controller decide to stop
system, for restart user must turn off S1 (inverter input) switch and turn on again.
2.4 SHUTDOWN MESSAGES :
HP-200P series UPS’s can operate interactive with operating system, you can send commands to UPS from
operating system by using some softwares .UPS takes this commands and produces some messages these
are:
WAITING SHUTDOWN : Shutdown command is performed from operating system and UPS is waiting
for a certain delay for shutdown.
UPS SHUTDOWN : UPS is in shutdown status
WAITING RESTART : UPS is shutdown but it is waiting for a certain delay for restart
PAR.SHUTDOWN : In parallel system the other UPS send shutdown command and UPS is in
shutdown status.
CANCEL SHUTDOWN : Shutdown command is cancelled.
Only operating system or a PC computer can send this commands.
If the shutdown command is performed during line failure UPS shutdowns and is the mains is okay UPS starts
again automatically.

III. PARALLEL OPERATION
3.1 Introduction
Two of HP-200P UPS can be used in parallel mode, the purpose of parallel use:
•Redundancy
•Power increment purpose.
3.1.1 Redundancy
Even if UPS designs are perfect sometimes some failures are possible. Also the lifetime of batteries and
some parts are limited. In such a case, the second UPS installed on the system will be working on.
3.1.2 Power Increase
Some load systems always develop and the power need increases, the cheapest solution is to install one
more UPS to the system.
3.2 Parallel Operation Mode
NOTE: Parallel control board and some accessories are not installed in a standard HP-200P series UPS, but
parallel operation option is available for these models.
User can select parallel operation mode as an option according to purpose. If parallel control board is installed
in your UPS, you can select operation mode from SETTINGS MENU. In this chapter you can find parallel
operation mode information.
The general diagram of parallel connection is shown below:
