NOTE
All electrical connections must be carried out by
an authorised electrician.
Electrical installation and wiring must be carried

ELK 15 must be installed on terminal block X1 via a circuit
breaker with a minimum breaking gap of 3 mm.
ELK 15 contains temperature limiter and two contactors to
control the two power steps, 5 kW and 10 kW. For the best
function, the power should be binary controlled, i.e. 5, 10
and 15 kW.
The electrical circuit diagram is at the end of this Installer
