Mounting the EPM External I/O Modules

EPM 9450/9650 ADVANCED POWER QUALITY METERING SYSTEM – INSTRUCTION MANUAL
A mounting bracket kit (p/n PL9000-MBIO) is required in order to install the I/O modules,
and must be ordered separately. Order one mounting bracket kit per module group. Each
mounting bracket kit includes mounting brackets, screws, and a cable.
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 EPM 9450/9650 meter will supply power for a
number of I/O modules. See Section 5.6.2 to see if you need to use an additional power
supply, such as the GE PSIO. Connect multiple I/O modules using the RS485 side ports.
Six feet of RS485 cable harness is supplied with the mounting bracket kit (p/n PL9000-
MBIO). The cable harness brings power to the display from the EPM 9450/9650 meter. See
Chapter 5 for power supply and communication details.
