Introduction
The m tt:e range of Electric Vehicle Charger Connection Units are
fitted with O-PEN technology designed to protect Electric Vehicle
Charging equipment when installed onto 3 phase PME infrastructures.
The unit incorporates a 5 pole isolator with a built-in under-voltage
release mechanism. On detection of fault conditions the O-PEN
electronic circuit de-energises the under-voltage release mechanism
which disconnects all poles of the supply including CPC. The 5 pole
isolator is manually resettable in line with IET Wiring Regulations and
code of practice.
If the O-PEN monitor detects a fault and activates the isolator the
monitor must be reset by cycling power to the unit. It does NOT
automatically reset.
The m tt:e O-PEN technology does not require earth rods or measuring
electrodes to function correctly.
The units are designed to be installed indoors between the distribution
board and the Electric Vehicle Charger. The unit must be mounted
securely to a solid surface with the lid hinges on the left.
The inst ll tion loc tion should be cle n, dry nd well ventil ted.
Please refer to the diagrams on the following pages for the dimensions
and mounting arrangement of the units

Connect the incoming cable from the distribution board directly to the
4 pole isolator. The CPC should be connected to the terminal block
Connect the outgoing cable(s) to the MCB, RCBO or 5 pole isolator
depending on the unit being installed. The outgoing CPC should be
connected to the isolated earth bar except for the EVU-1-63-TP.
THIS PRODUCT IS DESIGNED FOR AN ISOLATED
EARTHING ARRANGEMENT. CHECK BEFORE USING
SWA CABLE
On completion of inst ll tion the tightness of ll electric l
connections should be checked before energising the unit.
See specific tions for tightening torques.

Operating Instructions
With the incoming isolator closed the unit will monitor the incoming
supply. Approximately 1 second after closing the incoming isolator the
O-PEN monitor will energise the under-voltage release mechanism of
the 5 pole isolator. At this point the 5 pole isolator can be closed to
connect the load to the incoming supply.
In the event the O-PEN unit detects a fault condition on the neutral of
the monitored supply for a period of 4 seconds the internal relays will
de-energise and remove the supply to the under-voltage release
mechanism of the 5 pole isolator. This will cause the 5 pole isolator to
open disconnecting all phases, neutral and CPC from the load.
After any fault condition is detected causing the monitor to enter a
tripped condition the monitor must be reset by cycling power to the
unit via the 4 pole incoming isolator
Test Function
A Test Switch is provided to allow the functionality of the
units to be checked. With the unit powered and the 5 pole
isolator closed rotate the Test Switch anti-clockwise to
position O to initiate a test. This will disconnect L1 from the O-PEN
monitor and create a fault condition. After 0.7 seconds the O-PEN
monitor will trip the 5 pole isolator by de-energising the under-voltage
release mechanism. We recommend the unit is tested on a 6 monthly
basis.
