To check a proper connection of a ground wire to the inverter, perform the following
steps:
1. Ensure that the Ground (PE) wire is connected to the designated location on the
enclosure of the Synergy Manager and the Synergy units.
2. Use a continuity tester to check the continuity between the ground wire, inverter's
enclosure, metal conduits, and the earth. The tester should indicate a continuous
circuit.
Fan Maintenance
Each Synergy Unit has a cooling fan at can be accessed from the bottom panel of the
enclosure. Keep the fan clean and free of dust. When needed, and at least once a year,
open the fan screen and clean the accumulated dust using a brush.
Check the fan to make sure it is functioning properly and is free of dust and debris. A
dirty fan can cause the inverter to overheat, reducing its efficiency.
1. Turn ON/OFF/P Switch of the Synergy Manager to OFF (0).
2. Turn OFF the DC Disconnect Switch on the front cover of the Synergy Manager (see
"Front Interface of Synergy Manager " on page 35) and the AC breaker on the
distribution panel.
