Electrical Connections Air Top Evo 3900/5500
10. Electrical Connections
All the cables and wires that are not required must be insulated against accidental shorting or grounding.
NOTE:
The electrical connection is made as shown in the system circuit diagram (Figure 35).
10.1 Heater Connection
To connect the wiring harness, remove the control unit cover on the heater and connect the wiring harness plug to the
control unit.
Figure 26. To remove the control unit cover
NOTE:
Raise the control unit cover on both sides using a blunt blade (Figure 26 arrows).
Before using the heater for the first time, fit the control unit cover in place on the heater to prevent the escape of hot
air (heater overheating).
The cable passage of the cover can be placed at either the left or right side.
To ensure that the cable passage in the control unit cover seals perfectly, the cable grommet is to be adjusted
appropriately on the wiring harness.
10.2 Supply Voltage Connection
Ideally from the vehicle’s central electrical system or at the batteries.
A weather sealed fuse holder is to be fitted to protect the heater
(supplied with the heater harness).
IMPORTANT!
The Air Top EVO 3900/5500 requires 6.25 amps @ 12 volts or 12.5 amps @ 24 volts during start-up.
The main power connection has to be made at a circuit designed to sustain this load without
voltage drop. Cigar lighter sockets and auxiliary power outputs for C.B. radio’s and other
electronic accessories are not considered adequate power supplies for the Air Top EVO 3900/5500.
F = 20A (12V)
F = 15A (24V)
