This manual covers the ARD-1-32-TP-3-32-M unit.

The unit is not intended for any purpose other than that defined within this document.

WARNINGS

Please read and observe the following notices. 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 per the IET Wiring Regulations, BS7671 (18th Edition or later) and any relevant Building Regulations and/or Installation Regulations.
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.

Safety Advice

The unit must be installed in a dry ventilated location; it must never be covered or have restricted ventilation.

The ARD-1-32-TP-3-32-M units are rated for a maximum of 63A.

Introduction

The matt: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-energizes 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: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 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.

Electrical Connections

The user wiring connections are indicated in the image below.

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 MCBs.
The outgoing CPC should be connected to the green isolated earth bars.
THIS PRODUCT IS DESIGNED FOR AN ISOLATED EARTHING ARRANGEMENT. CHECK BEFORE USING THE SWA CABLE
On completion of installation, the tightness of all electrical connections should be checked before energizing 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 energize 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 4 seconds the internal relays will de-energize 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.
Once the fault condition has cleared the O-PEN unit will reset after 3 minutes 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 be tested on a 6-monthly basis.
