■ Circuit as delivered:

12 kW Y 400 V 3 ~ (11 kW Y 380 V 3 ~)

Connection Options:

– 8.0 kW 230 V ~ (7.4 kW 220 V ~)

– 6.0 kW 230 V ~ (5.5 kW 220 V ~)

(The required optional bridge can be found under

accessories.)

■ To guarantee compliance to relevant safety regulations,

an all-pole separator must be ﬁtted during installation.

The contact opening must be at least 3 mm.

■ Terminal BZ45Z20M (special accessories) can be used

if the connecting cable is fed into the continuous-ﬂow

heater via one of the bottom holes 14a!

■ The wires must not interfere with the operation of release

button A on the safety temperature limiter.
