5.6 Firing pulse inhibit
The firing pulse inhibit function provides a simple way of switching
to high power levels.
A contact between connections 6 and 7 can be used to switch off the load.
The external contact can be a make or break contact, depending on the
position of S105.

Factory setting S105 is in position 1
5.7 Resistance output
When the converter is operating within rated limits, the resistance output has a
voltage of 4 ... 5 V.
V In order to be able to disconnect a system from the supply voltage,
a circuit-breaker or main switch for all-pole disconnection must be
wired into the supply feed!
A
If the output power is simply removed by inhibiting the firing
pulses, this does not provide electrical isolation from the voltage
supply! The terminals D or 1D may still carry dangerous voltage
from the supply.
External contact Internal switch S105 Response
Make (a) Position 1 The load is permanently
switched off when the contact
is closed
Break (b) Position 2 The load is permanently
switched off when the contact
is open
