Liebert NXC Communication
Chapter 7 Communication
This chapter briefly introduces the UPS communication.
The communication ports include: Intellislot cards port, opto-coupled port, dry contact port and USB port.
7.1 Installing Intellislot cards
7.1.1 Intellislot card Port
UPS provides an Intellislot card port (see Figure 7-1), which is used to install the communication device options, including
global connectivity cards and LIFE.net adapter. The Intellislot card port and USB port can be used at the same time.
Figure 7-1 Intellislot card installation
Refer to UPS Extended Dry Contact Card User Manual for the installation and operation guide.
7.2 Connection cables for dry contact port and opto-coupled port
The UPS provides two dry contact ports and three opto-coupled ports; see Figure 1-3 for the specific positions. The silk prints
of the five ports are 1, 2, 3, 4 and 5. The pin layout of each port is shown in Figure 7-2, and the port description is shown in
Figure 7-1. Cable cross-sectional are 0,1-1,5mm
