(1) An individual output should not be subjected to high power loads and then be required to run low power loads.
(2) Output current maximum per module is limited by the maximum output power rating.
(3) 14 gauge wire connected to all terminals may not allow the field wiring arm cover to close. A smaller wire size may be required.
(4) You use this conductor category information for planning conductor routing as described in the system-level installation manual.
