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.
