What are the pinouts for the Output Relay on the Environmental Monitoring Unit (AP9319) and the Environmental Management System (AP9320)?



Below are the pinouts:

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.
