Failure to install or operate this instrument in accordance with the instructions contained in this manual may create hazardous operating conditions.
1.1 Safe Use of Equipment
The equipment supplied has been designed and manufactured to ensure safe operation. The equipment must only be used within the design parameters.
The instructions within this manual must be observed as an aid towards achieving the safest possible installation.
Persons responsible for installation, maintenance, or operation, must observe the following instructions:
1.1.1 Changes to Equipment
Changes in the design and modifications to the equipment are not permitted. Unauthorised changes made to the hardware or operating firmware will void the manufacturer's warranty, and may compromise the integrity of the system into which it is installed and other connected equipment.
1.1.2 Equipment Knowledge
Experience with, or understanding of, this equipment is essential for the safe installation and removal of the equipment. Therefore, please read and understand this manual prior to use. Competency based training courses are recommended and are available on request.
1.1.3 Manual Handling
Precautions have been taken to ensure all equipment is safe to handle and free from sharp edges. However care should always be taken when handling enclosures and gloves should be worn.
1.1.4 Installation
Correct operation and safety depend on the relay and associated equipment being installed correctly. Mechanical and or electrical installation and maintenance of plant and equipment must only be carried out by appropriately qualified personnel and must be tested thoroughly prior to operation.
1.1.5 Operation
As safety depends on the relay functioning correctly it is highly recommended that all safety functions of the relay be periodically tested to ensure correct operation.

2 RECEIVING AND STORAGE
2.1 Receiving
All possible precautions are taken to protect the equipment against damage or losses during shipment, however before accepting delivery, check all items against the packing list or bill of loading. If there is evidence of physical damage, notify Ampcontrol immediately.
Notify Ampcontrol immediately in case of any discrepancies to the packing list. Keep a record of any claims and correspondence. Photographs are recommended.
Where practicable do not remove protective covers prior to installation unless there are indications of damage. Boxes opened for inspection and inventory should be carefully repacked to ensure protection of the contents or else the parts should be packaged and stored in a safe place. Examine all packing boxes, wrappings and covers for items attached to them, retain and store any approval documentation for your safety file as applicable prior to wrapping being discarded.
2.2 Inspection
Equipment that is found to be damaged or has been modified away from its published specification must not be used. Please contact Ampcontrol if the equipment is suspected to be different than that ordered or if it does not match the published specifications.
2.3 Storage after Delivery
When the equipment is not to be installed immediately, proper storage is important to ensure protection of equipment and validity of warranty.
All equipment should be stored indoors between 0-40˚C, preferably on shelves and protected from moisture and sunlight.
2.4 Unpacking of Equipment
The method of packing used will depend on the size and quantity of the equipment. The following cautions should be interpreted as appropriate.
CAUTION!
Take care when unpacking crates as the contents may have shifted during transport.
The disposal of packaging materials, replaced parts, or components ENVIRO must comply with environmental restrictions without polluting the soil,
air or water.
Ensure that any timber and cardboard used as packaging is disposed of in a safe and environmentally responsible manner.
Where possible, dispose of all waste products i.e. oils, metals, plastic and rubber products by using an approved recycling service centre.

3 PRODUCT OVERVIEW
3.1 ELD V3 Earth Leakage Relay
The Ampcontrol ELD V3 Earth Leakage Relay is electronic in design and is based on microprocessor technology. It is designed to AS/NZS 2081:2011 Section 6.
The earth fault current is measured using a toroid, with the trip time and trip threshold being able to be independently adjusted using selectors on the relay fascia. When a fault occurs and the trip level and time delay is exceeded the relay‟s trip function is activated. A trip will de-energise the trip contacts connected in the system control circuit. The trip condition is latched in non-volatile memory and requires operation of the reset input to clear the trip condition. An internal reset is also provided on the fascia of the relay.
A ten-segment LED bar graph indicates the percentage of leakage level being detected. This reading can be remotely monitored/displayed using the 4-20mA output of the relay. When the relay measures currents with frequencies much greater than 50Hz, the bar graph LED fast flashes (5Hz) instead of being steady. Should the high frequency current persist until the time delay is exceeded the relay will trip and the „Har.Trip‟ LED (Harmonic Trip) will be illuminated.
The ELD V3 Earth Leakage Relay is housed in a stainless steel case and can be either „DIN Rail‟ or „Panel‟ mounted through a 69 x 39mm cut out. When panel mounted the front of the relay is designed to provide IP56 ingress protection. There is provision to prevent unauthorised adjustment of the trip settings by sealing the post (in front of the knurled nut) with a lead seal or the use of a padlocked cover (see the equipment list for part number), thus inhibiting the unauthorised removal of the front fascia cover.
An internal switch mode power supply allows the ELD V3 to operate from 24VAC to 110VAC or 24VDC to 150VDC

Figure 3-2: Core Balance and Series Neutral Installation Types
The ELD V3 Relay has been designed and tested for use on fault-limited systems. To ensure maximum protection the earth leakage system should be used in conjunction with the other protection systems covered by AS/NZS 2081. The collective systems are designed to limit touch and step potentials.
The relay is also suitable for industry where equipment or system earth leakage protection is required. The relay is not suitable for personal protection, which requires trip levels of 20-30mA, with instantaneous operation (refer to AS/NZS 3190).
The ELD relay continually monitors the toroid and if the connection is lost the relay will trip and flash the „CT Fault‟ LED. This function is disabled in the alternative part number 179723, see below for further details.

3.2Accessories
3.2.1DIN Rail Mounting Kit (101399)
The ELD V3 is designed to be panel mounted, however a DIN rail mounting kit can be separately purchased.
Figure 3-3: DIN Rail Mounting Kit (Suit ELM / ELD / ELV)
3.2.2 Lockable Cover (164672)
A separately purchasable Lockable Cover is available to install over the fascia of the ELD V3 relay. This can be used to prevent earth leakage resets being performed by unauthorised personnel.
