The information provided in this literature is believed to be accurate (subject to change without prior notice); however, use of such information shall be entirely at the user’s own risk.

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).

Apply power, the green “supply on” LED will illuminate and the “positive safety output” relay will energise. The relay

will de-energise if:

** causes the “standard output” relay to energise in response to the fault condition.

Prior to a fault occurring, the LED bargraph will indicate the % of I n being detected (the display is scaled between 25,

50, and 75% of the actual trip level). After all 3 LED's have illuminated and the unit trips due to an excessive fault

current, the red “tripped” LED will illuminate. The unit will now remain in a latched condition.

The unit can be placed into a fault condition by pressing the “Test” button on the front of the unit (or by pressing the

remote “Test” button - if fitted). The output relays operate accordingly.

Press the “Reset” button on the front of the unit (or remotely - if fitted) to reset the unit. The output relays revert back

to their “non-tripped” state.

The unit can also be reset by interrupting the power supply.

To satisfy regulations, it is recommended that the device be tested periodically to ensure correct operation.

If the unit fails to operate correctly check that all wiring and connections are good.

For the DC supply version, ensure the polarity to terminals 6 and 7 (A1 and A2) are correct.

Pluggable connectors located at the rear of the unit and supplied with mating, re-wireable sockets

Designed to monitor and detect true RMS earth fault currents (up to 30A) in conjunction with a separate C.T.

LED bargraph provides constant indication of any leakage current

Microprocessor controlled with internal monitoring (self-checking)

Adjustable Sensitivity (I n) - 30mA to 30A

Adjustable Time Delay ( t) - 0 (instantaneous)* to 10 seconds

Separate “Test” and “Reset” push buttons

Connection facility for remote “Test” and “Reset” push buttons

Toroid open circuit detection forces unit to trip (Red LED flashes during this condition)

behind panel and excluding pluggable connectors.

Note:

1. For I n setting of 30mA, the time delay is fixed to 0 (instantaneous) and is not adjustable (i.e. any

other time delay cannot be selected when 30mA is set).

2. The unit is factory set to 30mA trip and instantaneous delay. Adjustment of these settings can be

made if necessary to suit the requirements of the installation. A seal is supplied allowing the user to

secure the clear window and hence prevent any unnecessary adjustment of the settings.
