AFA4000/2 Airflow Monitor / p.9
2.5 Electrical safety
Lethal voltages are present at certain points within the equipment.
When the equipment is connected to mains power, removing the
equipment's covers is likely to expose live parts.
Even when the power switch is off, high voltage can still be present.
Capacitors within the equipment may still be charged even if the equipment
has been disconnected from all live voltage sources.
Connect the Airflow Monitor and associated equipment correctly to a suitable electrical
supply. The supply must have a correctly installed protective conductor (earth or
ground), which must be installed and checked by a qualified electrician before initial
power up.
Any interruption of the protective conductor inside or outside the Auto-Sash
Controller System, or disconnection of the protective conductor terminal is
likely to make the equipment dangerous.
Never interrupt the protective conductor.
If the mains power cord needs to be replaced, ensure that the replacement
cord is appropriately rated and approved for the intended use.
To prevent potential personal injury and damage to the equipment, switch
OFF all components in the system and disconnect them from the mains
power supply before altering or making any new electrical connections.
When working with the Airflow Monitor System and/or the Auto Sash Controller System:
•
Do not operate equipment with any covers or internal parts removed.
•
Disconnect the equipment from live voltage sources before adjustments,
replacements, maintenance or repairs are carried out. If the equipment must be
operated during adj
ustment, maintenance or repair, only a supplier’s Service Engineer
is to carry out the procedure.
