shows the dry contact location inside the front panel, and Figure 3.6 on the facing page, shows the connection details. Table

selections, and factory details.
NOTE: The terminal block wire range is 18AWG to 22AWG (0.82mm

), and we recommend using 18 AWG
copper, shielded, and signal cable.
All input dry contact ratings are 12 VDC, 20 mA maximum. The output dry contact rating is 24 VDC, 0.5 A maximum.
The inputs expect the external dry contact to be N.O. and to close in order to trigger the alarm/action. The output dry
contacts are N.O. and close in order to trigger the alarm/action.
NOTE: We recommend that you route the cables for the dry contacts from the rear of the UPS through the built-in
wiring channel to the dry contact port connections. See Figure 2.2 on page7, for the location of the pass through.
