Page 6: General Information
ELEKTRA Heating Cables Note: Heating cables must be installed according to the Instructions. Mains connection of the heating cables should be performed by an authorized electrician. General information When protecting external areas from snow and ice deposition, it is required to assess the required heat output value per ft ) of the surface. - Page 7 For this purpose, DIN-bus installed controllers ELEKTRA ETO2 can be utilised. Snow & ice protection controls ELEKTRA ETOG2 controller – max. load up to 3x16 A. For applications in extended heating systems. As standard, equipped with one temperature and moisture sensor and an installation tube.
