reset.
INVERTER STOP−This red pushbutton, when pressed, enables the user to stop any run-
ning operation. Pushing this button will open the ac and dc circuit breakers.
WEB SERVER CONNECTION−The user can use this connection port to connect locally
to the system via Human Machine Interface (HMI) mode.
PRE-CHARGE−This key-lock is used when any work or maintenance requires the
inverter to be de-energized. When the inverter stop pushbutton is pressed and the pre-
charge key is turned to the OFF position (ac and dc circuit breakers are open), the
inverter bridge will discharge to a safe level in 5 minutes.
WARNING
Capacitors in the PCS may have residual charge after the pre-charge key has been
turned off. If there is no load connected to the unit, wait 5 minutes for the capacitors to
discharge before proceeding with work or maintenance.
When the pre-charge key-lock is in the OFF position, the key can be removed. The
inverter bridge will remain de-energized until the key is placed back in and turned to the
ON position (and source power is restored). Once the key-lock is in the ON position, the
key cannot be removed unless it is turned back to the OFF position.
