1.0 INTRODUCTION
1.1 Summary of the manual
This handbook provides for the safe installation, startup and use of the EDP70 PLUS Uninterruptible Power
System (UPS). The Company recommends that the equipment be installed and regularly maintained by a
Chloride Authorized personnel.
DO: - read the User Handbook before operating the EDP70 PLUS UPS.
- keep a log of all incidents.
- protect the batteries from damage. Batteries leak acid; avoid contact with skin,
clothes or eyes.
DO NOT: - operate the control switches.
- operate the EDP70 PLUS UPS with any covers removed.
- obstruct the ventilation grilles.
1.2 Summary of the equipment
The EDP70 PLUS Uninterruptible Power System (UPS) totally isolates the load from voltage drops, spikes,
transients frequency variations in the utility supply.
In the event of failure or brownout of the AC utility supply, an internal audible alarm sounds and an LED on the
control panel illuminates, the EDP70 PLUS UPS will continue to provide safe, clean continuous power, without
interruption, from the battery, for a duration dependent on battery capacity and output load.
The audible alarm alerts the user to start a safe orderly shutdown of the load. When the AC utility supply returns to
normal, the EDP70 PLUS UPS automatically recharges the battery ready for any future power failure.
The microprocessor display panel provides access to very detailed information regarding the status of the supplies
and EDP70 PLUS UPS. Refer to current publication for detailed specification.
The block diagram, shows the main functional sub-assemblies of the EDP70 PLUS UPS. The AC three phase
utility supply is rectified to provide direct current, which maintains the battery in a fully charged state and also
supplies the inverter, which provides the three phase output via an electronic static switch.
Normally the supply of the reserve line is taken from the AC utility input, but special units, with a separate reserve
input supply, are available. This allows the inputs to be supplied from independent three phase sources.
Provided the reserve supply is within limits, the inverter will match the output frequency with the reserve supply
frequency. The inverter has its own internal crystal control to stabilize the output frequency if the reserve supply
frequency is out of limits. The electronic static switch switches the output from the inverter to the reserve supply,
without interruption, to meet any load current surges, or to supply the load if the battery is discharged during an AC
utility supply failure.
Maintenance and testing can be carried out on the EDP70 PLUS UPS without interrupting the output, by switching
the load from the reserve supply to the maintenance bypass circuit. This work should only be carried out by
Chloride-trained personnel.

The uninterruptible power system consists of the following:
1 - RECTIFIER/INVERTER S1 = Equipment ON/OFF switch
2 - BATTERY S2 = Equipment Reserve switch
3 - BACKFEED PROTECTION S3 = Equipment By-pass switch
4 - INVERTER STATIC SWITCH S4 = Equipment OUTPUT switch
5 - RESERVE STATIC SWITCH (INVERTER OUTPUT switch for 50/80kVA only)
S5 = RESERVE OUTPUT switch for 50/80kVA only
1.4 Functions
RECTIFIER / BATTERY CHARGER
The rectifier/battery charger transforms the alternating current of the mains supply to direct voltage to maintain the
battery in a fully charged state and also supply the inverter.
BATTERY
The battery is an energy reserve that is used by the inverter and the load whenever the mains supply fails.
INVERTER
The inverter changes the direct voltage from the rectifier or from the battery into a three phase sinusoidal
alternating voltage for the external supply.
ELECTRONIC STATIC SWITCH
The function of the electronic static switch is to select one of the two sources of alternating voltage and to supply it
to the external load. The two sources of voltage supplied to the static switch are the output of the inverter and the
reserve supply. In normal working conditions, the static switch supplies the load from the inverter.
SWITCHES
The switches permits maintenance and repair of the UPS, without interrupting the supply to the load.

Figure 4 – Utility Supply failure
When the utility supply voltage is absent or outside the allowed tolerances, the battery supplies the inverter. This
will be indicated on the UPS front panel display and the Remote Alarm Unit (if fitted). The standby time available
depends both on the capacity of the battery and on the size of load. It is possible to extend autonomy by reducing
the output power by disconnecting non-important loads. In all cases, the alphanumerical display shows the residual
autonomy.

Figure 6 – Transferring the Load onto the Reserve Supply
Transfer onto the reserve line is caused by two conditions:
a) inverter stop
b) overload
In both instances the load is transferred onto the reserve without interruption. If the overload is temporary, the
system will re-transfer from reserve to inverter as soon as the it ceases. This allows for the initial start-up of loads
with high or excessive switch-on currents.
