7 Input Dry Contacts
The UPS provides two sets of input dry contacts that are open by default. The default setting for Pin 1 and 2 is "ROO" and the
default setting for Pins 3 and 4 is "Generator Power Supply Signal". There are two configuration types:
Figure 6-6 shows the first type of input dry contact configuration. It requires internal power, +12VSF.
Figure 6-7 shows the second type of input dry contact configuration. It requires external power with a voltage range between
6~12V DC.
8 REPO Port
The REPO port is for remote emergency power off. When an emergency event occurs, it will disconnect the UPS power supply rapidly
and shut down the UPS immediately. The configuration is shown as follows.
