2.7. Communication Connections
The UPS oers several communication interfaces and ports.
NOTE: We recommend that signal-cable lengths be less than 10 ft (3 m), and are kept away from power cabling.
2.7.1. Connecting IntelliSlot Communication
The IntelliSlot ports accepts two optional cards:
The Liebert® IntelliSlot™ Relay card (IS-RELAY) card provides dry-contact relay output for custom-wired
applications.
The Liebert® IntelliSlot™ Unity card (RDU101) provides SNMP and/or RS-485 monitoring of the UPS across the
network and/or building management system and lets you monitor external temperature, humidity and contact-
closure inputs using external sensors. It also delivers support for Trellis® Power Insight™ software.
See the appropriate gure for your model in Rear Panels on page 5, for the location of the card port.
To install an IntelliSlot Card:
1. Remove the screws from the slot cover plate and remove the plate.
2. Insert the card into the slot, and secure with the screws that held the cover plate.
To make connections to the card, refer to the Liebert® IntelliSlot™ Installer/User Guide for the appropriate card
available at www.VertivCo.com.
2.7.2. Connecting to the Dry-contact Port
The UPS includes a dry-contact port. See the appropriate gure for your model in Rear Panels on page 5, for
the location of the port. Figure 2-10 below, shows the ports and Table 2-4 on the facing page, describes each port.
The I/O dry contact port capacity is 125 Vdc, 0.5 A; 30 Vdc, 1 A
