WARNING! If signal cables are connected,
the individual wires must be bound togeth-
er with a cable tie directly upstream of the
terminal. This prevents any wire making
contact with dangerous voltages if it works
loose.

OUTPUT - heating element continuously
adjustable up to 3 kW
NOTE! Phase and neutral conductors
must not be mixed up. Residual cur-
rent-operated circuit breaker is triggered.
