Notes
•
Maintain 0.25 in. (6 mm) spacing between power-limited and nonpower-limited wiring.
• NAC circuits are power-limited and supervised for opens, shorts, and overcurrents. When
configured as auxiliary power circuits, they are power-limited and supervised for shorts and
overcurrents.
• Source must be power-limited. Source determines supervision.
• Position the battery terminals towards the door.
