Disconnector Control

D000029326 en g – E450 PLC 1-phase ZCX100Px – User Manual
The E450 meter has an integrated disconnector to connect or disconnect
power to the customer premises. The disconnector can be controlled:
•
Manually, with an integrated push button or via a pulse input where an
external push button is wired
•
Remotely, from the metering system
•
Locally, with dlms commands via optical port or by demand super-
vision.
There are five different operating modes for disconnector control available.
These modes define in which situation the disconnector can be controlled
remotely, locally or manually.
The mode is defined within the meter configuration. Details on the operat-
ing modes are described in the E450 functional description.
Disconnector not suitable as main switch
Do not use the disconnector as a main switch for installation or mainten-
ance purposes. The disconnector is not equipped with a thermal and/or
short circuit protection device.
The current state of the disconnector is displayed on the meter display, see
section 5.1 "Display".
When the disconnector push button is actuated, first the capacitor for the
disconnector motor activation will be charged (this lasts about 10 seconds).
The disconnector switches therefore with a delay of approx. 10 second
after actuating the push button.
