WIRING GUIDE – NON-CONTROL VALVE APPLICATIONS
The wiring diagram on the following page represents the two terminal block groups located on the bottom
DIN rail of the ISM-4080 System. The right-side connections will need to be wired onsite. Please note
that not all sites will use all of the terminals. It is the responsibility of the installer to determine which
terminals will be used based upon the individual site configuration.
Only a qualified electrician familiar with the site should make the electrical connections outlined below.
Please contact VMI if you have any questions or concerns.

IS SWITCH I/O TERMINALS:
IS switch wiring connections are to be made using low capacitance data cable, 1 twisted pair, 24 AWG.
Please note that VMI recommends a high-quality shielded cable rated for data communication when
wiring the IS switches.
Automation Direct Part Number L19827-1 is an ideal cable for this application.
If using another cable, please ensure that the cable specifications meet or exceed the ratings of this cable.
Properly landing the cable shield line(s) to the designated terminals is imperative for proper system
operation. Do not connect the cable shield line to a chassis ground. Doing so will likely cause system
instability and/or false alarms.
