Installation & Wiring
If using a spliced terminal connection for longer runs, one module can be
connected to the E-BUS Distribution Module and any additional modules
would be daisy-chained to the fi rst module. For more information, refer
to the E-BUS Distribution Module Technical Guide.
NOTE: Contact Factory for the correct HSSC cable length for
your application. Cables are available in ¼, ½, 1, 2, 3,
4, and 5 Meter lengths and 100 and 150 Foot lengths.
WARNING: Be sure all controllers and modules are
powered down before connecting or
disconnecting HSSC cables.

WARNING!!
Observe Polarity! All
boards must be wired with
GND-to-GND and 24 VAC-
to-24 VAC. Failure to
observe polarity could
result in damage to the
boards.
