6.6. Fire Mode

Optidrive VTC has an integrated 'Fire Mode' function, designed to ensure that the Optidrive can continue to operate without interruption in the
event of a fire. Fire mode disables non-critical trip functions of the Optidrive, so that the Optidrive will continue to operate until either the drive
itself, the motor or the cabling is destroyed by the fire.
Since normal operation of the Optidrive is overridden when fire mode is active, it is possible that damage to the ventilation system may result from
over-pressure. It is also possible that the Optidrive may itself fail or cause damage to the motor.
Invertek Drives Ltd accepts no liability for damage to the Optidrive VTC itself, other components or equipment, HVAC installations, property or
injury to personnel when operated in Fire mode.
In no event shall Invertek Drives Ltd be liable to any party for loss or damage, whether direct or indirect as a result of operating the drive in Fire
Mode.
