Volt-free messages via the relay card (optional)

Description of the relay card
There is also the option to fit the UPS unit with a relay card
(optional)
.
This relay card provides voltage-free contacts for external further use. These contacts are designed a standard
as closing contacts, that is they close in the case of a fault. There is also a possibility of designing these
contacts as opening contacts by reversing a jumper on the relay card. The relay card also makes the electronic
– STOP – function available. This function is deactivated as standard over a bridge on the relay card. If the
electronic-STOP functionality is used then the bridge should be removed from the plug and an external switch
(opener) is to be clamped on the rear plug. Actuation of the external electronic STOP switch causes the output
of the UPS unit to be switched voltage-free and the UPS unit shuts down. In order to supply consumers with
voltage again it is necessary for the electronic STOP switch to be reset and for the UPS to be restarted. There is
still a
voltage
inside and at the terminals even after the electronic STOP function was activated.
The messages which are available on the relay card are as follows:
