9.3 USB port (optional)
Connection of the UPS to a computer is also possible via the USB interface at the rear of the UPS unit. If the
USB interface is to be used then simultaneous use of the RS 232 interface is not possible. Communication
between the UPS and the computer takes place via a conventional USB connection cable (PC: plug -A /
UPS unit: plug -B) and can only be used with the software “ UPSMON “ delivered as standard and the
optionally obtainable JUMP software.
10. Special equipment
10.1 Electronic STOP function
The UPS is fitted with an integrated electronic STOP function. This function is
deactivated as standard via a 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.
