1.6 Electrical Safety
The Airflow Monitor and associated equipment are designed to protect the user from
potential electrical hazards. This section describes some recommended electrical safety
practices.
The Airflow Monitor and associated equipment must be correctly connected to a
suitable electrical supply. The supply must have a correctly installed protective conductor
(earth or ground) and must be installed and checked by a qualified electrician before
initial power up.
When working with the Airflow Monitor System:
• Connect the equipment to a correctly installed mains power outlet that has a protective
conductor connection.
• Do not operate the equipment with any covers or internal parts removed.
• Disconnect the equipment from all live voltage sources before opening it to make any
adjustments, replacements, maintenance or repair. If the opened equipment must be
operated for further adjustment, maintenance or repair, this must only be done by a
supplier’s Service Engineer.
If it is possible that the equipment is no longer electrically safe for use, make the
equipment inoperative and secure it against any unauthorised or unintentional operation.
The electrical safety of the equipment is likely to be impaired if:
• It has any signs of visible damage.
• If it has been subjected to prolonged storage in unfavourable conditions.
• If it has been subjected to severe stress during transportation.
Any interruption of the protective conductor inside or outside
the Airflow Monitor System, or disconnection of the protective
conductor terminal is likely to make the equipment dangerous.
Intentional interruption of the protective conductor is prohibited.
