The potential-free contacts of external moni t or ing de-
vices (e.g.safety humidistat "B1") are connected in series
(safety chain "K") to the terminals "SC1" and "SC2" of
the terminal block "X6" on the driver board in accord-
ance with the wiring diagram.
The connecting cable must be led through a cable gland
into the control compartment.
Note: If, for whatever reason, no external monitoring de-
vices are connected, a jumper wire "J" must be installed
on the contacts "SC1" and "SC2" of the terminal block.
CAUTION! Do not apply any external voltage to
contacts "SC1" and "SC2" via the contacts of the
external monitoring devices.

The potential-free contacts (max. contact load 250V/5A)
of external moni t or ing devices (e.g.safety humidistat
"B1") are connected in series (safety chain "K") to the
terminals "SC1" and "SC2" of the terminal block "X3" on
the driver board in accordance with the wiring diagram.
The connecting cable must be led through a cable gland
into the control compartment.
Note: If, for whatever reason, no external monitoring de-
vices are connected, a jumper wire "J" must be installed
on the contacts "SC1" and "SC2" of the terminal block.
CAUTION! Do not apply any external voltage to
contacts "SC1" and "SC2" via the contacts of the
external monitoring devices.
DANGER! There is mains voltage (up to 240 V) at the
connection terminal "X3". Therefore, disconnect the
steam generator from the power supply before you start
the connection work.
