3.3: Mounting the Nexus
®
External I/O Modules
Secure the mounting brackets to the I/O using the screws supplied (#440 pan-head
screws). Next, secure the brackets to a flat surface using a #8 screw with a lock
washer.
If multiple I/O modules are connected together, as shown in Figure 3.5, secure a
mounting bracket to both ends of the group. One Nexus® will supply power for a
number of I/O modules. See Sections 5.6.2 to see if you need to use an additional
power supply, such as the EIG PSIO. Connect multiple I/O modules using the RS485
side ports.
Six feet of RS485 cable harness is supplied. The cable harness brings power to the
display from the Nexus® meter. See Chapter 5 for power supply and communication
details.
