Important Wiring Considerations
Please carefully read and apply the following information when wiring
the E-BUS Distribution Module:
1. All 24 VAC wiring must be connected so that all ground
wires remain common. Failure to follow this procedure
can result in damage to the controller and connected
devices.
2. All wiring is to be in accordance with local and national
electrical codes and specifi cations.
3. Minimum wire size for 24 VAC wiring should be 18
gauge.
4. Be sure that all wiring connections are properly inserted
and tightened into the terminal blocks. Do not allow wire
strands to stick out and touch adjoining terminals which
could potentially cause a short circuit.
5. Be sure all modular wiring harness connectors are seated
fi rmly in their respective modular connectors on the circuit
board.
NOTE: Contact Factory for the correct HSSC cable length
for your application. Cables are available in 1/4, 1/2,
1, 2, 3, 4, and 5 Meter lengths and 100 and 150 Foot
lengths.
NOTE: For Terminal Block Connection, see Figure 5.
WARNING: The E-BUS Distribution Module must be
powered down before connecting the HSSC
cable to a VCM-X or SA Module.
