1. SAFETY PRECAUTIONS
The AIR 403 has been designed with your safety in mind. However, there are inherent
dangers involved with any electrical and/or mechanical equipment.
Safety must be the primary concern as you plan the location, installation and
operation of the turbine. At all times be aware of electrical, mechanical and rotor
blade hazards.
1.1 Mechanical Hazard
Rotating blades present the most serious mechanical hazard. The AIR 403’s rotor blades
are made of very strong thermoplastic. At the tip, the blades may be moving at velocities
over 300 miles per hour. At this speed, the tip of a blade is nearly invisible and can cause
serious injury. Under no circumstances should you install the turbine where a person
could come in contact with moving rotor blades.
CAUTION: DO NOT INSTALL THE TURBINE WHERE ANYONE CAN APPROACH
THE PATH OF THE BLADES.
1.2 Electrical Hazards
The AIR 403 is equipped with sophisticated electronics designed to provide protection from
overcurrent electrical dangers. The internal electronics of the AIR 403 prevent open circuit
voltages from rising above 23 volts for 12-volt systems or above 45 volts for 24-volt systems.
Please note that the inherent personal dangers from electrical current still exist, therefore
caution should always be used when connecting this and other electrical devices.
Heat in wiring systems is often a result of too much current flowing through an undersized
wire or through a bad connection. It is important to follow the wire-sizing chart in Section
3.1.2 on page 10 to insure a safe electrical system.
CAUTION: FOLLOW THE WIRE SIZING CHART IN SECTION 3.1.2 ON PAGE 10
TO HELP AVOID THE RISK OF AN ELECTRICAL FIRE.
Batteries can deliver a dangerous amount of current. If a short occurs in the wiring from the
batteries, a fire can result. In order to avoid this threat, a properly sized fuse or circuit
breaker is required in the lines connecting to the battery. Refer to Section 3.1.4 on page 12
for fuse sizing information.
CAUTION: FUSE ALL CONNECTIONS. FOLLOW THE FUSE SIZING GUIDELINES
IN SECTION 3.1.4 ON PAGE 12 TO MINIMIZE THE RISK OF AN ELECTRICAL
FAILURE.
