RISK ANALYSIS AND DESCRIPTION
Noise pollution due to installation in unsuitable environments or where
individuals routinely work and/or animals dwell most of the time.
Suitable local ventilation that does not cause overheating of the
equipment and is sufficient not to create discomfort to people in the
room.
External weather conditions, water seepage, low temperatures, high
humidity, etc.
Overheating of surfaces at temperature (transformers, coils, etc. ) can
cause burns.
Inadequate cleaning compromises cooling and does not allow the safety
labels to be read.
Accumulation of electrostatic energy can generate hazardous discharges.
Inadequate training of staff.
During installation, temporarily mounting the equipment or its components
may be risky.
Despite the warnings and safety systems, there are still some residual
risks that cannot be eliminated.
These risks are listed in the following table with some suggestions to
prevent them.

SUGGESTED REMEDY
Reassess the environment or the
place of installation.
Restore suitable
conditions and air the room.
Maintain ambient conditions
suitable for the system.
Use suitable PPE. Wait for the
parts to cool down before opening
the inverter. Do not restrict cooling
openings or heatsinks.
Clean the equipment, labels and
work environment
Ensure components
discharged their energy before
working on them.
Ask for a supplementary course.
Prevent unauthorized
