5.6.2 Electrical air heater
The electrical air heater is wired in one or several switching groups. Each switching group for three-phase power
has three connection terminals plus one terminal for grounding each switching group.
Devices with electrical air heaters require a separate mains connection for the electrical air heater.
This supply line must be fused by the customer.
