2.2 FUNCTIONAL DESCRIPTION
The PowerPro ELXA is a modular Static Inverter (SI) comprising power module, distribution and
batteries in one cabinet.
All components are all accessed from the front of the cabinet with all power connections
located at the top of the PowerPro ELXA cabinet.
MCB1
: Mains Input Circuit Breaker.
MCB3-8
: Output Circuit Breaker.
MCB2
: Battery DC Circuit Breaker.
AVR: The first stage of the concept uses a single phase controlled automatic voltage regulator
as a form of surge protector. An AVR monitors the voltage constantly to deal with both dips
and spikes. This feature includes “Buck” and “Boost” technology to output regulated and
controlled voltage at a selectable figure.
CHARGER: In ELXA Series EL INVERTERs, a controlled charger is used to produce DC voltage for
both charging the batteries.
BATTERIES: Batteries are used as reserve DC power supply for the Inverter in case of mains
failure. Batteries are connected in series to obtain a DC supply. Batteries are discharged by
the inverter during mains failure. The discharged batteries are re-charged by the Rectifier on
a constant voltage / current limiting basis, if AC mains power is available.
INVERTER: The Inverter converts the DC BUS voltage supplied by the batteries into a well
regulated, fully digital controlled AC voltage with fixed voltage and frequency.
The output of the inverter is used to supply the critical loads connected to the EL INVERTER
output.
STATIC TRANSFER SWITCH (STS): This is an electronically controlled transfer switch, which
enables the critical load to be connected either to inverter output or to by-pass power source.
During normal operation, the load is supplied by the mains output, in case of a mains
disturbance or a mains failure the load is automatically transferred to the inverter source.
Figure 2.1. Electrical Block Diagram

2.3 MODES OF OPERATION
Changeover mode
When operating in the ‘changeover’ mode the rectifier is turned on to provide
battery charging. The inverter is turned on and operating on standby (off load) The bypass-side of the static switch is
turned on to connect the SI OUPUT to the AC INPUT via the internal bypass line.
If the utility supply fails, the static switch will transfer the SI OUPUT to the inverter within 10ms. However, as the
utility supply is in a failed state the rectifier is inoperative and the inverter will be powered solely from the
batteries (see Figure 2.5).
Figure 2.2
On battery operation
If the mains supply fails, the rectifier turns off but the inverter will continue to operate from battery power until the
batteries reach their end-of-discharge voltage; at which point the inverter will shut down and disconnect the
SI OUTPUT supply.
If the AC INPUT supply is restored before the batteries are fully discharged, the rectifier will turn on automatically to
once again power the inverter and recharge the batteries.
The whole process of switching between rectifier and battery power is totally transparent to the emergency
luminaires.

2.3.3.2 AUDIBLE ALARMS
During a utility failure or fault operation, the EL-Inverter a emits beeping sound for warning. In
back-up mode, the alarm can be silenced by pushing the “MAIN CONTROL ON/OFF BUTTON”
button. However, the warning of low battery will still sound urging user that load will be lost.
2.3.4 TEST SWITCH
If the EL-Inverter is in normal operation it is supplying the load by the incoming utility supply. In
the case of a failure in this supply, the output is connected to the static inverter output. This
transfer operation is performed internally by the control logic of the Inverter.
The operation of the EL-Inverter can be controlled externally; the unit can be forced to supply the
output by the Inverter and batteries. This can be achieved by turning the TEST button.
Note: When the equipment is switched into the Test mode, the red “TEST ON” LED will
be lit.
The TEST Button or the external test loop can be used for testing the machine’s operation
and performance; it can also be used to maintain the EL-Inverter’s loads.
WARNING: When the TEST button has been used, it is important that it is switched
off so the EL-Inverter can return to a standby operation and the batteries
are recharged.

3.3 INSTALLATION
3.3.1 ENVIRONMENTAL CONSIDERATIONS
A certain amount of pre-planning will help provide a trouble-free installation process. You should
consider the following guidelines when planning the installation location and operating environment.
1. The route to the installation location must allow the equipment to be transported in an upright
position.
2. The floor at the proposed installation site and en-route from the off-loading point must be able to
safely support the weight of the cabinet/battery equipment, plus fork lift or trolley jack during transit.
3. The cabinet requires sufficient front and rear clearance to enable cooling airflow, as described below.
4. All maintenance, servicing and user operation can be carried out from the front of the cabinet, but rear
access is required for connecting the AC and DC power cables.
5. An ambient temperature of 20°C is necessary to achieve the recommended battery life span.
6. The cooling air entering the cabinet must not exceed +40°C.
7. The floor material should be non-flammable and strong enough to support the heavy load.
8. In summary, the system should be installed in a location where:
a) Humidity (< 93%) and temperature is ideally 20°C.
b) Fire protection standards are respected.
c) Cabling can be performed easily.
d) A minimum 800mm front accessibility is available for service or periodic maintenance.
e) Adequate cooling air flow is available.
f) The air conditioning system can provide a sufficient amount of air cooling to keep the room at,
or below, the maximum desired temperature (where used).
g) No dust or corrosive/explosive gases are present.
h) The location is vibration free.
3.3.2 CLEARANCES
Cooling air enters from the right hand side of the cabinet and exhausts from the left hand side.
a) You should provide a minimum of 800mm clearance at the front of the cabinet to allow the power
module(s) to be removed/installed.
b) You should provide a minimum of 250mm at both sides.
c) The cabinet does not require any rear clearance for cooling purposes so it can be installed immediately
to the wall.

17
3.3.4 CABLE CONSIDERATIONS
It is the customer’s responsibility to design and install the PowerPro ELXA supply and distribution circuits,
and provide all the external fuses, switchgear and cables required to connect the cabinet’s AC INPUT and
SI OUTPUT supplies. The information provided in this section should assist you in the planning and
preparation of the power cabling.
The AC INPUT terminals should be connected to a utility mains LV-switchgear panel and protected by a
circuit breaker or fused isolator.
Similarly, the SI OUTPUT terminals should be connected to the load equipment via a suitably protected
load distribution panel.

3.3.5 INRUSH CURRENT
Special Consideration should be taken when installing luminaires with very high inrush
characteristics.
The Inrush Current of LED Luminaires is determined by the driver (s) and is not proportional to
the luminaire wattage or running current, LED luminaire inrush currents can be as high as 400
times the running current for a very short period of time.
Further information regarding LED inrush currents can be found by accessing the “LIA Technical
Statement LIA TS35” from the LIA website (www.thelia.org.uk).

3.3.6 CABLE SPECIFICATION
All cables and protective devices must be selected in accordance with national and local regulations and
codes of practice (e.g. BS7671:2008 or relevant country standards) to suit the maximum capacity of the
system, as shown in the table below.
NOTE: If you install a system containing fewer than six power modules with a view to increasing the system
capacity it at a later date as your load increases, you should consider using cables rated for the maximum
system rating at the outset. This will simplify the future update process and avoid having to shut-down the
system at a later date to replace the power cables. ALL power modules have internal fuse protection
