Below are the pinouts:
| Pin # | Description |
| 1 | No Connection |
| 2, 3 | Normally Closed (NC) Contact |
| 4, 5 | Common |
| 6, 7 | Normally Open (NO) Contact (recommended connection) |
| 8 | No Connection |
Relay ratings: 1A, 30V AC/DC
Since the user interface allows for either 'normally open' or 'normally closed,' APC recommends using only the normally open contacts and configuring the 'normal' state in the user interface.
