Eaton 93PS UPS 8–40 kW
6.3
This standard feature lets you connect smoke detectors or over-temperature
alarms to your signal inputs. The user interface terminals for external
connections are located inside the UPS. Use twisted-pair wires for each alarm
input and common.
The signal inputs can be programmed to display the alarm functional name.
6.4
One general purpose relay contact is provided as a standard feature on the
UPS. An alarm contact is also provided.
You can use a normally-closed or normally-open contact. If the state of the
contact changes from the state you specify as normal, a signal is issued. You
can connect this contact to equipment at your facility (such as a light or an alarm
bell) to let you know when an alarm is active on the UPS. This feature is useful if
the UPS is located in a remote area where the UPS horn may not be heard
immediately.
Note: Do not operate the contacts in excess of 30 VAC (RMS) and 30 VDC at
5 A maximum.

93PS offers one native relay output. Additionally, each of the 2 MiniSlots can be
equipped with a relay card, including 5 relays. The following instructions guide
you through the relay configuration.
Currently the relay configuration can be done only using the display. The service
tool does not yet have support for nodebit functions.
The maximum voltage of the relay is 30 V. Check the voltage and current
specifications of the other cards from the previous sections.
The process for relay configuration is as follows:
1.
In the home screen of the display, click the lock icon in the top right corner
to type in the service password.
2.
In the sign in window, click the password field containing the 4 dots.
