EXICOM’s power plants are equipped with in-house produced Switched Mode Rectifiers (SMR). We have power
plants configurations with ampere ultimate capacity ranging from 100A up to 4000A (for instance 100A, 200A,
400A, 800A, 1000A, 2000A, 2500A, 3000A etc.), which provide regulated power to telecommunication equipment
and also keep batteries floated across the load in fully charged condition so that uninterrupted operation of vital
communication network continues even when AC mains fail.
Today’s sensitive electronic loads and state of the art VRLA batteries require continuous electronic supervision
and features like Temperature Compensation, Battery path current limiting etc. A micro -controller based
Monitoring and Control Unit (M2000) carries out all these vital functions.
All the above modules and sub-assemblies are housed in a rack. Because of the modularity of the whole
architecture the system is extremely flexible. A variety of combinations can be worked out to serve any kind of
requirement and provision for future expansion.

Please read the safety instructions very carefully before operation to avoid harm to the personnel or the system.
The special instructions laid in this book does not include all the safety points to be observed, and are only
supplement to various safety points. Therefore, the installation and commissioning personnel must be strictly
trained to correctly and cautiously operate the system.
Warns of a hazard the system operator will be exposed to, that will likely result in death
or serious injury if not avoided.
Warns of a potential hazard the system operator may be exposed to, if not avoided, that
may result in equipment damage or performance loss.
Notifies an action to the reader that must be avoided or performed in order to protect
equipment, software, data, or service.
Hazardous Voltage
Some components of the power system carry hazardous voltage in operation. Direct or indirect
contact through moist objects with these components will result in fatal injury.
Safety rules in the industry must be observed when installing the power system. The
installation personnel must be strictly trained to operate high voltage and AC power.
In operation, the installation personnel are not allowed to wear conductive objects such as
watches, bracelets, bangles, rings etc.
When water or moisture is found on the Sub-rack, turn off the power immediately. In moist
environment, precautions must be taken to keep moisture out of the power system.
Tools
In high voltage and AC operation, special tools must be used. No common or self-carried tools
should be used.
Thunderstorm
Never operate on high voltage, AC, iron tower or mast in the thunderstorm.
In thunderstorms, a strong electromagnetic field will be generated in the air. Therefore the
equipment should be well earthed to avoid damage by lightning strikes.
ESD LOGO
The static electricity generated by the human body will damage the static sensitive elements
on PCBs, such as large-scale ICs. Before touching any plug-in board, PCB or IC chip, ESD wrist
strap must be worn to prevent body static from damaging the sensitive components. The other
end of the ESD wrist strap must be well earthed.

Short Circuit
During operation, never short the positive and negative poles of the DC distribution unit of the
system or the non-grounding pole and the earth. The power system is a constant voltage DC
power equipment, short circuit will result in equipment burning and endanger human safety.
Check carefully the polarity of the cable and connection terminal when performing DC live
operations.
Never wear a watch, bracelet, bangle, ring, or other conductive objects during operation.
Insulated tools must be used.
Battery
Before any operation on battery, read carefully the safety precautions for battery handling and
the correct battery connection method.
Non-standard operation on the battery will deteriorate battery efficiency and may cause
danger to battery or operating personnel.
In operation, precautions should be taken to prevent battery short circuit and overflow of
electrolyte. The overflow of electrolyte will erode the metal objects and PCBs, thus causing
equipment damage and short circuit of PCBs.
Before any operation on battery, pay attention to the following points:
Remove the watch, bracelet, bangle, ring, and other metal objects on the wrist.
Use special insulated tools.
Use eye protection device, and take preventive measures.
Wear rubber gloves and apron to guard against electrolyte overflow.
In battery transportation, the electrode of the battery should always be kept facing
upward. Never put the battery upside down or slanted.
BLVD
The system has battery low voltage disconnection (BLVD) function. BLVD means when the mains
fail and batteries supply power, the monitoring module cuts the load off when the battery
voltage drops down to below 44.4V to prevent over-discharge. The BLVD voltage is settable
through controller (M1000).
The factory setting is enabling BLVD, which means that if power outage lasts for a long time or
the power supply system fails, there might be BLVD. Users should classify the loads and connect
the priority loads to BLVD routes.
For vital loads, users can disable BLVD of these loads to insure reliability of the power supply.
The advantage of enabling BLVD is protecting the batteries from over-discharge when the
battery voltage is low. The disadvantage of enabling BLVD is that when the battery voltage
drops down to a certain value, all the loads (including non-priority loads and priority loads) will
be cut off due to battery disconnection.
The advantage of software disabling BLVD is prolonging the power supply of priority loads. The
disadvantage is that software disabling cannot prevent unwanted power failure due to mis-
operation or power supply system failure.

Sharp Objects
When moving equipment by hand, protective gloves should be worn to avoid injury by sharp
object.
Cable Connection
Please verify the compliance of the cable and cable label with the actual installation prior to
cable connection.
Binding the signal lines
The signal lines should be bound separately from heavy current and high voltage lines, with
binding separation of at least 150mm.
General Safety
A Good Earth. Typical earth resistance should be less than 1 ohm, for lightening protection;
earth resistance should be periodically verified (once in three months).
In case of DG set supply, adequately rated DG set to cater for minimum 1.25 times of Power
Plant load and maximum of other loads (e.g. starting load of AC). In case of three phase DG set,
load on DG set should be balanced on three phases within +/-10%.
The Power plant has unity power factor and does not require external PF correction. Use of
switched capacitor bank at input results in switching transients which may damage the Power
plant and is to be avoided.
Without LPU installation/integration with SMPS/PP, do not Switch ON the Power Plant.
