Electronic STOP function
The UPS is fitted with an integrated electronic STOP function. This function is
deactivated as standard by measn of a short-circuit-bridge at the rear of the
UPS unit. If the electronic STOP functionality is to be used then the bridge
should be removed on the plug and an external switch (opener) clamped to the
rear plug. Actuation of the external electronic STOP switch causes the output of
the UPS unit to be switched to voltage-free and the UPS unit shuts down. In
order to provide the consumers with a voltage again the electronic STOP switch
must be reset and the UPS restarted. There is still a
voltage
inside and at the
terminals even after the electronic STOP function was activated.
