INSTALLATION
There is no need to remove the expansion module from its
case to complete the installation, wiring, or setup of the unit.
WARNING!
Do not connect or disconnect the expansion module
with the power on!
External Relays & Digital I/O Connections
The relay and the digital I/O expansion modules 101B224-03 &
101B224-04 are connected to the meter using a CAT5e cable provided
with each module (see Figure 1).

WARNING!
Do not connect any equipment other than Ashcroft’s
expansion modules, cables, or meters to the RJ45
M-LINK connector. Otherwise damage will
occur to the equipment and the meter.
The two RJ45 connectors on the expansion modules are identical and
interchangeable; they are used to connect additional modules to the
system.
Note: The jumper located between the RJ45 connectors of the
101B224-04 (see Figure 2) must be removed on the second digi-
tal I/O module in order for the system to recognize it as module
#2.
