Appendix D—Additional Wiring Diagrams December 1998

APPENDIX D— ADDITIONAL WIRING DIAGRAMS

HAZARD OF ELECTRICAL SHOCK, BURN, OR EXPLOSION.

• Turn off all power supplying this equipment before opening the

terminal shield or making connections.

• Close and snap the terminal shield before turning power on.

Failure to observe these precautions will result in death or severe

personal injury!

DANGER

SUPPORTED WIRING CONNECTIONS

Table D-1 on the following page describes various power systems supported

by the power meter. The table also shows which power meter system type

should be used (system I.D.) and how the power meter should be wired.

Figures D-1, D-2, and D-3 show CT, PT, and control power wiring. See

Chapter 5 for other wiring diagrams.

To comply with CE, see CE Compliance, page 22.
