DANGER!

FIRE MODE" FUNCTION – RISK OF DEATH!
Notice that the inverter is only one of the components of the system, and it is configurable for several
functions that must be pre-established in the project.
Therefore, the full operation of the "Fire Mode" function, with the required safety, depends on the
specification in the project, as it also requires the compatibility with all the other components of the
system and the installation environment.
Ventilation systems that operate in life safety applications must be approved by the Fire Department
and/or another competent local public authority.
The activation of the "Fire Mode" function disables essential protection functions for the safety of
the frequency inverter and of the system as a whole.
The non-interruption of the frequency inverter operation due to the improper activation of the "Fire
Mode" function is critical, as it may cause injuries or even death, and damages to the frequency
inverter, to the other components of the system and to the environment where it is installed.
The operation in the "Fire Mode" function may, under certain circumstances, result in fire, as the
protection devices will be disabled.
Only qualified personnel from safety engineer departments must evaluate and activate the
equipment Fire Mode function.
It is essential to follow the aforementioned instructions before using the frequency inverter in the
"Fire Mode" function.
Under no circumstance shall WEG take any liability for deaths, damages, compensations and/or
losses occurred due to the improper programming or operation of the frequency inverter in the "Fire
Mode" function.
IMPORTANT – RISK OF DEATH!
When activating the "Fire Mode" function, the user must be aware of the fact that the protection
functions of the frequency inverter will be disabled, which may result in damages:
1. to the inverter;
2. to the components connected to it;
3. to the environment where it is installed;
4. to the people present in the place.
Therefore, the operator who activates the "Fire Mode" function takes full liability for the resulting risks.
The operation of the inverter with the "Fire Mode" function programmed voids the warranty of the
product.
The operation in this condition is internally registered by the frequency inverter, and it may be validated
by an engineer and occupational safety professional duly qualified by the manufacturer.

NOTE!
When activating the "Fire Mode" function, the user acknowledges that the protection functions of
the frequency inverter are disabled, which may result in damages to the frequency inverter, to the
components connected to it, to the environment in which it is installed and to the people present in
such environment. Therefore, the user takes full liability for the resulting risks. The operation of the
inverter with the "Fire Mode" function enabled voids the warranty of the product. The operation under
such condition is internally registered by the frequency inverter and must be validated by an engineer
and occupational safety professional duly qualified. If the user presses the
disappear from the display (A211), but the operation mode will continue to be shown in parameter
P006. It is also possible to indicate this condition in a digital output (DOx) previously programmed for
"Fire Mode". During the operation in "Fire Mode", all the stop commands are ignored (even General
Enable). Some Faults (considered critical) that may damage the inverter will not be disabled, but they
can be infinitely reset automatically (define this condition in parameter P582): Overvoltage on the DC
Link (F022), Overcurrent/Short Circuit (F070).
