WARNING
The UPS contains hazardous voltages, even when all switches are open.
In case of fire in the installation area, do not use water to extinguish fire.
ELECTRICAL PRECAUTIONS:
If the UPS is in By-pass mode and the Output switch is closed, no indications will be displayed;
fans will however function, and hazardous voltages are present downline from the static
switches.
EMERGENCY PROCEDURE
In the case of an emergency, the load supply can be interrupted by switching off all the switches
fitted in the UPS.
ELECTRIC SHOCK
Switch off power; use dry insulating material for protection when pulling the injured person clear
of conductors.
NEVER TOUCH THE INJURED PERSON WITH BARE HANDS UNTIL CLEAR OF
CONDUCTORS. SEEK QUALIFIED ASSISTANCE IMMEDIATELY.
INJURIES CAUSED BY CONTACT WITH CORROSIVE LIQUIDS
In normal conditions, installed batteries are sealed. A damaged battery container may however
leak electrolyte, or cause the latter to come into contact with battery parts.
In the event of electrolyte contact with the eyes, rinse eyes thoroughly with a saline solution or
fresh water for at least 10 minutes.
In the event of electrolyte contact with skin, rinse the affected area with abundant water. Remove
contaminated clothing. Cover affected area with dry gauze.
If electrolyte is swallowed, do not induce vomiting. Administer large quantities of milk
The equipment and battery are delivered separately. On receipt, the packaging must be checked for any signs of
damage. Any damage or missing parts should be reported to the carrier within 24 hours of delivery.
Unpacking
Care should be taken when unpacking to avoid damaging the equipment or battery; in particular, avoid short circuiting
battery terminals. All packing materials should be checked before disposal to ensure that no items are discarded. The
equipment panel rating plate should be checked to ensure that supply voltage and output rating correspond to the
equipment and load and that the mode of operation is correct.
Handling
Keep equipment and battery upright at all times, and handle with care. Either may be damaged if dropped or subject to
severe impact. Particular care should be taken to protect the controls and instruments.
a) Leave the equipment in its packaging and transport it with a fork lift.
b) Cut the tapes and remove the packing case by lifting it upwards.
c) Unscrew the screws fastening the pallet to the cubicle feet.
d) Lift the cubicle and remove the pallet.
Storage
Store the equipment and battery in a clean, dry place, free from water, condensation, dirt and extremes of temperature.
Sealed lead acid battery cells which are supplied filled and charged must be given a boost charge at least every 3
months.
Sealed Nickel-Cadmium battery cells which are supplied filled and discharged must be charged and discharged before
storage.
Sealed Nickel-Cadmium battery cells which are supplied dry must be filled, charged and discharged before storage.
Sealed spare battery cells must be charged at least every 3 months.
Failure to comply with the Manufacturer’s instructions may result in the battery not reaching its rated performance and
having a shortened life.

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.

Figure 2 – Block diagram – 50/80kVA
The uninterruptible power system consists of the following:
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.
The battery is an energy reserve that is used by the inverter and the load whenever the mains supply fails.
The inverter changes the direct voltage from the rectifier or from the battery into a three phase sinusoidal alternating
voltage for the external supply.
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.
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.

3.0 STORAGE
If the EDP70 PLUS UPS cannot be installed within sixty days of delivery, there is a danger of the integral battery
becoming discharged thereby sustaining permanent damage and affecting the standby period available and battery life.
The date the battery was last recharged and the date the battery is due for its next recharge are both stamped on the
packaging accompanying the unit. If you intend to store the unit, please refer to the recharge date.
When the EDP70 PLUS is due to be recharged, refer to the Installation instructions and connect the EDP70 PLUS UPS
to a temporary AC supply. The battery MUST be recharged for at least 24 hours every 3 months.
