Vendor part number information is provided as a way to reduce component selection
times, since the suggested parts have already been verified to meet all required
specifications. Alternate component suppliers may be used provided that
all
specifications listed for each component are met. While surge testing must be performed
for every new product design, using the suggested vendor part numbers listed in tables
4.1 and 4.2 has the additional advantage that the same vendor parts were verified by
Echelon.
For three phase coupling applications, the coupling circuit shown in Appendix A of the

ORKS
Engineering Bulletin,
Centralized Commercial Building Applications with

PLT-21 Power Line Transceiver
(005-0056-01), is recommended.
Recommended coupling circuits for applications where two out-of-phase hot lines are
used (e.g., North American 240V appliances) and for 24VAC applications are listed in
