6.3.3. Power connection note
DANGER
Risk of serious personal injury and property damage and even death due to incorrect
connection of the kiln to the power supply.
⇒
The kiln should only be installed and connected to the electrical supply lines by qualified
electricians.
Notes:
⇒
For the operation of the kiln in workshops, laboratories and other environments, it is absolutely necessary to
have a separate power supply with its own protection provided by a qualified electrician.
⇒
An RCD residual current circuit breaker should be used for this (colloquially: RCCB or ELCB).
⇒
Under certain circumstances, an RCD residual current circuit breaker with a tripping current of 0.03 A may tend
to trip prematurely (e.g., due to room humidity or the moisture content of the ware).
⇒
A larger RCD residual current circuit breaker (0.3 A) could be selected as long as the selected circuit is used
exclusively for the kiln.
⇒
However, this decision should always be made by a qualified electrician.
⇒ If this cannot be guaranteed, a permanent connection must be provided.
⇒ Only connect the kiln with the power cable supplied - an extension cable must never be used.
⇒
Special feature of eDrive:
If a residual current circuit breaker is used in the version with eDrive, a Type B RCCB sensitive to all current
types must be used.
