INVERTER SHUTDOWN

THERMAL OVERLOAD A

This message indicates that an overload below 1.5 times the full power rating of the inverter has occurred and that the inverter has shut down. The flashing “A” indicates that the operator should check the load current.

I LOAD > IN

CHECK LOAD A

This message indicates that the load power being drawn is greater than the UPS full load rating. The flashing “A” indicates that the operator should check the load current. The inverter or static switch will keep supplying the load for a certain amount of time depending on the overload level.

TRANSFER FAULT

CALL SERVICE !

This message indicates that a fault has occurred that affects the transfer of the load between the inverter and the bypass source. Service is required.

PH OUT OF TOLERANCE !

This message indicates that there is an out of tolerance condition between the inverter and bypass AC input (mains 2) sources. Transfer of the load between the inverter and bypass AC input will result in an interruption of load power.

Q4S BYPASS SWITCH

OPEN !

This message indicates that the circuit breaker Q4S is open. Transfer of the load from the inverter to the bypass source is not possible.

Q5N UPS OUTPUT ISOL.

SWITCH OPEN !

This message indicates that the optional UPS isolation circuit breaker Q5N is open. The load is not supplied unless the maintenance bypass circuit breaker Q3BP is closed.

Q3BP MAINT. BYPASS

SWITCH CLOSED !

This message indicates that the optional maintenance bypass circuit breaker Q3BP is closed. The system is set to maintenance bypass, and the load is supplied by the bypass AC input source (mains 2).

STATIC SWITCH O.L.

EMERGENCY OFF !

This message indicates that the static switch has shut down following an overload condition, disconnecting the load.

DISPLAY NUMBER 1

UNAVAILABLE

This message indicates that the alphanumeric display is not operating properly. The status of the UPS is still correctly indicated by the LEDs of the visible panel and the hidden panel, see section 1.5 Single Module Indicators and Controls.

HARMONIC FILTER

FUSE FAILED

This message indicates that the fuse(s) protecting the input harmonic filter has opened and that service is required. The status of the UPS is still correctly indicated by the LEDs of the visible panel. Refer to section 1.5 Single Module Indicators and Controls for front and hidden panel indicators and controls.
