PRECAUTIONS FOR OPERATION
xOperating method.
-To obtain stable operation, it is advisable that the UPS is operated on a continuous
basis. Even if you start or stop the equipment at daily intervals, keep the converter
running and start or stop the inverter alone.
xExtended shutdown.
-If the UPS is placed into stopped state for durations of the order of several months,
operate the converter for a day or two at monthly intervals. (Charge the batteries. Left
uncharged for a long time, they can run down due to self-discharge.
xDo not touch live parts even after equipment is shut down.
-Because the converter is kept operational after the stoppage of the inverter, voltage
remains applied to the internals of the equipment. Also, it takes about 5 minutes after
the stoppage of the converter for voltage across the DC circuit to dissipate to a safe
level in the range of 20V. Avoid contacting the live part of the equipment and the
supply side of the breaker because they stay energized in this way even after
equipment shutdown steps are performed.

MITSUBISHI ELECTRIC 1100 SERIES UPS
1.4 OPERATION OVERVIEW
The UPS provides two power paths between the utility source and the critical load.
Figure 1.1 shows the path for normal operation, with the load powered from the inverter.
Figure 1.2 shows the path for bypass operation, with the load supplied through the static
bypass line.
A) Normal operation: Load power supplied by UPS inverter.
Figure 1.1 Single Line Diagram - Normal Operation: Load powered by UPS inverter
During normal operation, the path through the UPS inverters is used to power the load.
Referring to Figure 1.1: Input AC power is converted to DC by the Converter. DC power is
utilized to charge the UPS battery and to provide power to the Inverter. The Inverter
converts the DC power to clean AC power to supply the critical load.
The conversion - inversion process eliminates any voltage transients or fluctuations existing
in the input power before it reaches the critical load.
WARNING : The Bypass input circuit breaker (MCCB) for protection
of the UPS and cables are field supplied and field
installed. (See WARNING 4 on page 1-7).

B) Bypass Operation: Load power supplied through UPS internal static bypass line.
Figure 1.2 Single Line Diagram - Bypass Operation: Load fed through static bypass line.
Referring to Figure 1.2: The Internal bypass line is a hard-wired line through 52S which
supplies the critical load with unconditioned bypass input power. Upon switching to the
internal bypass line, the static transfer switch line through CB3 (herein after STS contactor
CB3) supplies the power immediately, and then the internal bypass line through 52S
supplies the power. In the event of a switching to the bypass line, the power to the critical
load will be uninterrupted. The purpose of this internal bypass line is to route power to the
critical load while the UPS module is de-energized (converter and inverter), and during
start-up before the system is fully operational.
In the event of a load overcurrent, the UPS transfers to bypass without interruption to the
critical load.
The internal control system determines the operation of the two paths, with the load
powered from the inverter being the normal operation.

C) Battery operation: Load power supplied by UPS battery.
Figure 1.3 Single Line Diagram - Battery Operation
Referring to Figure 1.3: In the event of AC input source failure or interruption, the UPS
converter will de-energize and the UPS battery will immediately discharge and supply DC
power to the inverter to maintain continuous AC power to the load. This operation will
continue until:
a) The battery capacity expires and the inverter turns off, or
b) Input power is restored after which the converter will power the inverter and critical load
and simultaneously recharge the batteries.
A fully charged battery will provide power for the specified time at the rated load, or longer,
at a reduced load.
When power is restored after a low battery shutdown, the UPS converter automatically
restarts operation, the charger recharges the batteries and the Inverter is automatically
restarted without operator intervention. Load is automatically assumed by the inverter
without operator intervention.
