2. Detach the communication terminal connector from the MODBUSCARD.
3. Slide the configured MODBUSCARD into the UPS accessory slot
4. With the screws that were removed in step 1, attach the compatible cover plate that came with MODBUSCARD to the
accessory slot mounting points.

6. The MODBUSCARD’s red LED will flash to indicate the UPS is connected and ready for communication.
