This unit should be installed in conjunction with the latest wiring regulations and practices (IEE, etc)

Type: ELRV-30

Earth Leakage Relay (Variable) - Type A

Note: The voltage

across the fault level

output MUST NOT

exceed 240V~ (For

400V~ units used in

3-Phase installations,

connect the load between

terminal 2 and neutral)

Both relays are shown

in the de-energised state

(i.e. where power is not

present on terminals 1 and 3)

* Only available on AC supply models

CONNECTION DIAGRAM

FUNCTION DIAGRAM

BEFORE INSTALLATION, ISOLATE THE SUPPLY.

Connect the unit as shown in the diagram below (N.B. certain features may not be required and

therefore do not need to be connected).

Operational and setting information can be found on the reverse of this data sheet.

MOUNTING DETAILS

INSTALLATION

(i.e. lamp)

70mm DIN rail housing

Designed to monitor and detect earth fault currents (up to 30A) in conjunction with a separate toroid

Digital LED Display shows measured leakage current as well as various user settings

Microprocessor controlled with internal monitoring (self-checking)

Sensitivity (I n) and time delay ( t) adjustable using simple 2-button operation

“Display” push button allows user to view settings without needing to open the tamperproof cover

Single button operation for “Test / Reset” and connection facility for remote “Test” and “Reset” push buttons

Connection for remote lamp facility warning user prior to a trip condition (level adjustable by user)

Toroid open circuit detection forces unit to trip

The Earth MUST NOT pass through

the toroid.

For single phase applications, only the live

and neutral need to be passed through the

toroid.

*Cabling:

For distances >1m, use twisted pair cable between

the unit and toroid. Always ensure cables to toroid

and remote test / reset switches ARE KEPT AWAY

from mains and data cables in the same installation.
