Connecting optional annunciator cable
Use the following procedure to connect a user-supplied cable between the solid-state relay on a
redundant power supply to an input module in the chassis. The normally open relay is held closed
during normal operation and opens when the power supply fails or is turned off.
ATTENTION
The annunciator output is rated for resistive loads. Do not use it to drive the coil of an
electromagnetic relay.
1. Open the redundant power supply door.
2. Connect the source voltage lead to one of the terminals on the solid-state relay connector, as
shown below. The source voltage must be compatible with the input module.
