NOTE: this is a block diagram only ; the earth circuit connections are not shown but must nevertheless be implemented. If the fan is fitted with a two speed motor, the regulation system must ensure that a reduction in the air flow rate immediately leads to a proportional reduction in the battery power :
Caution: the surge current and the resultant rating of the protective devices must be calculated by the installer depending on the supply voltage on the site. installer). Provide a 3 to 5 minute time delay on the fan to cool the heater coil. (top to bottom).
At low speed, the power dissipated by the heater coil must not exceed 30 kW.
