Product Description
The matt:eElectric Vehicle Charger Connection Units are designed for
use in commercial applications where 3 phase PME supplies are
feeding Electric Vehicle Chargers.
This manual covers the ARD-1-63-TP unit.
The unit is not intended for any purpose other than that defined within
this document.
WARNINGS
Please read and observe the following notices carefully. These
warnings must be observed when installing and operating the Electric
Vehicle Charger Connection Units.
All relevant supplies must be isolated or disconnected before commencing
any work. This product must be installed by a competent person in
accordance with the IET Wiring Regulations, BS7671 (18th Edition or later)
and any relevant Building Regulations and/or Installation Regulations.
Safety Advice
The unit must be installed in a dry ventilated location; it must never be
covered or have restricted ventilation.
The ARD-1-63-TP units are rated for a maximum 63A.
For any information not contained within this document, please contact our
technical support team on 01543 227290 or [e-mail].
Once installed, the unit has a Live Mains Supply (400v or higher)
within the enclosure. The cover must not be removed until the
supply to the unit has been isolated or disconnected.

Introduction
The matt:erange 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 will automatically reset after a PEN fault, but must
be manually reset after an overcurrent fault in line with IET Wiring
Regulations and code of practice.
The matt:eO-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 installation location should be clean, dry and well ventilated.
Please refer to the diagrams on the following pages for the dimensions
and mounting arrangement of the unit.

Installation instructions
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 5-pole isolator.
THIS PRODUCT IS DESIGNED FOR AN ISOLATED
EARTHING ARRANGEMENT. CHECK BEFORE USING
SWA CABLE
On completion of installation the tightness of all electrical
connections should be checked before energising the unit.
See specifications for tightening torques.

Operating Instructions
With the incoming isolator closed the unit will monitor the incoming
supply. If no fault condition is present approximately 1 second after
closing the incoming isolator the O-PEN monitor will energise the
under-voltage release mechanism of the 5 pole isolator (indicated by
the green LED illuminating). At this point the 5 pole isolator can be
closed to connect the load to the incoming supply. Alternatively wait
30 seconds and the isolator will automatically close.
In the event the O-PEN unit detects a fault condition on 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
5pole isolator. This will cause the 5 pole isolator to open disconnecting
all phases, neutral and CPC from the load.
Once the fault condition has cleared the O-PEN unit will reset after a 3
minute period and the 5 pole isolator will automatically reclose 30
seconds after
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.
