Page 8: Product Overview
3 PRODUCT OVERVIEW 3.1 ELV Earth Leakage Relay The Ampcontrol ELV Earth Leakage Relay is electronic in design and is based on microprocessor technology. It is designed to AS/NZS 2081:2011 Section 6. The ELV Relay uses patented technology (AU2011264414) to characterise earth leakage currents giving superior fault discrimination, particularly in applications involving switching power electronics and variable speed drives. -
Page 9: Figure 3.2: Core Balance And Series Neutral Installation Types
(refer to AS/NZS 3190). The ELV Earth Leakage Relay continually monitors the toroid and if the connection is lost the relay will trip and flash the ‘CT Fault’ LED. Uncontrolled Copy - Refer to Ampcontrol Website for Latest Version Page 9 of 40... -

Page 13: Installation
It is extremely important that the limitations and functionality of the ELV Relay are understood to prevent incorrect installation and use from creating a potentially dangerous risk. If in doubt as to the nature of the limitations or their implication, consult a competent authority such as a supervisor or Ampcontrol technical representative. -

Page 17: Electrical Installation Information
These terminals are for the connection of the ELV’s earth leakage toroid. The ELV Earth Leakage Relay is designed for use with Ampcontrol EL500S series 100:1 Toroids. They are available with window sizes 25, 60, & 112 mm. These allow trip settings from 30 mA to 2.5 A. - Page 18 20 mA represents an earth leakage current of 120 % of the trip level. The 4-20 mA output should be wired as per Figure 4.6. NOTE Ampcontrol does not recommend using the 4-20 mA output as the main tripping signal. All tripping should be carried out by the provided output relays.

Page 25: Equipment Maintenance
WARNING! All repairs must be carried out by Ampcontrol only. If a fault develops, return the ELV Relay to Ampcontrol for repair. It is essential that no attempt be made to repair the ELV Relay as any attempt to dismantle or repair the ELV Relay can seriously compromise the safety of the unit and voids product warranty. -

The effect of this is that a small output may be obtained from the toroid where none would arise if the device were ideal. Uncontrolled Copy - Refer to Ampcontrol Website for Latest Version Page 34 of 40... - Page 35 Select the smallest internal diameter toroid, which will allow the cables to fit through. Avoid very large toroids (200 mm) or toroids with square apertures. The ELV Relay has been designed for use with the Ampcontrol EL500S series of toroids. For ordering part numbers, refer to the Equipment List in Section 10.

Page 38: B3 Weighted Wideband Earth Leakage Protection
It is impractical for the user to utilise these curve sets directly in touch potential calculations. Both Ampcontrol VSDguard and ELV Relays are capable of weighting the wideband E/L current as a function of frequency according to the curve sets in AS/NZS 60479. This weighting accounts for the differing effects of frequency on fibrillation risk automatically, and while the actual current measurement is wideband, the weighting produces a ’50 Hz equivalent risk’... - Page 39 Ampcontrol holds an international patent (PCT/AU2011/000705) in regard to the use of frequency discrimination as applied to earth fault protection.
