INSTALLATION INSTRUCTIONS for the
RESIDUAL VOLTAGE DEVICE
READ CAREFULLY
The Residual Voltage Device unit provides additional layers of electrical protection to any RCD/RCBO
enabling enhanced operation within earthed and unearthed environments, providing a broader range of
fault detection.


The RCD/RCBO remains the front line of protection, detecting and isolating earth related current
imbalance fault conditions,

Provides enhanced electrical protection in high impedance Earth situations that have geographically
inherent problems such as sandy/hard rocky soils where achieving a low impedance earth is difficult,

Enables RCD/RCBO to provide electrical protection within IT and TT earthing systems.

Provides protection if Supply Neutral or Main Earth is Lost.
GENERAL INSTRUCTIONS
Only to be installed by a Licensed Electrical Contractor.
1. When Active to Earth faults occurs the RCBO (Not supplied) should trip at 30mA, once the fault has
cleared simply turn RCBO to the on position.
2. When an Active to Frame voltage fault (43Volts) occurs, the Residual Voltage Device should trip at
20mA. Once the fault clears, reset the Residual Voltage Device flag and RCD/RCBO to the ‘on’
position.
3. Total current of protected circuits must not exceed maximum current rating of the RCD/RCBO.
4. Fixed appliances such as ovens and hot water services should be connected on individual circuits as
RCD/RCBO’s can be sensitive with these products.
5. Ensure the ‘Main Earth’ and ‘Main Neutral’ are in good condition.
6. Always follow the RCD/RCBO manufacturer’s instructions, the Residual Voltage Device instructions
are to be used in addition to those instructions.
7. Please contact Safe Electrical Technology if further assistance is required.
Installation Procedure
The Residual Voltage Device unit is designed for final sub-circuit protection in low voltage installations
(240V or 110V).
Ensure Power is isolated and RCD/RCBO is in the ‘off’ position and ‘lock out’ procedures followed.
Check that the rated voltage of the RCD/RCBO installation to be protected is in accordance with
manufacturers specifications.
Please note that the Residual Voltage Device does not need to sit immediately alongside the
RCD/RCBO, but cables will need to be run to the RCD/RCBO. Give consideration to this during ‘planning’
for the installation.
1. Mount the RVD unit onto the Din Rail either ‘next to or nearby’ the RCD/RCBO circuit to be
protected.
2. Cut the Yellow/Green Earth/Frame cable to length and terminate in earth link or equipment frame,
3. Cut to length and insert additional Blue/Black Neutral cable between the RCD/RCBO Lineside/Supply Neutral (L2) cage terminal and the Residual Voltage Device Line side cage terminal.
4. Cut to length and insert Brown/Red Active cable between the RCD/RCBO Load-side Active or L1
cage terminal and the Residual Voltage Device Load side cage terminal.
All terminations should be tightened to a torque of 2Nm or RCD/RCBO manufacturers specified
torque setting.
Note: If using in IT or TT earthing systems, ensure that RCD/RCBO is capable of
double pole switching- isolating both Active/L1 and Neutral/L2 conductors.

TEST THE UNIT MONTHLY - INSTRUCTIONS
1. Test in conjunction with RCD/RCBO.
2. Both the RCD/RCBO and RVD’s need to be tested monthly.
3. First press the test button on the RCD/RCBO. To reset, reposition the
RCD/RCBO to the ‘on’ position.
4. Test the Residual Voltage Device by pressing the orange test button. The
RCD/RCBO will isolate. To reset, depress the blue flag and turn the RCD/RCBO to
the ‘on’ position.
5. Insert RCD Tester and carry out testing as per Manufacturer’s Instructions
after setting trip level at 30mA.
6. If the Residual Voltage Device does not isolate or allow RCD/RCBO to reset,
after verifying that 43 volts is not present on the frame, then the unit may be
faulty. Discontinue use, if applicable return to Safe Electrical Technology for repair.
Note: 2 lights for MEN and 3 lights for Isolated earthing systems is normal, proceed
with normal test regime.
Some automated RCD Testers will not permit testing as ‘No earth’ is present. SET
recommends use of Testers without the ‘No earth’ function.
