▶Before reaching into the system, switch off the power supply and
secure to prevent reactivation.
▶Observe applicable accident prevention and safety regulations for
electrical equipment.
Risk of burns/Risk of fire if used continuously through hot device
surface.
▶Keep the device away from highly flammable substances and media
