with opened contact.
Activation via
fl
oating contacts, a low voltage of approx. 24 V DC is connected.
Danger due to electric current
•
No disconnection (no potential isolation in accordance with VBG4
§
6) in remote control of the
device!
•
Never apply line voltage to the digital input!

Relay outputs
“
K1
”
An external fault indicator is available over the potential-free contact of the built-in relays (max. contact
rating
Technical data and connection diagram).
Function factory setting for
“
K1
”
:
•
For operation the relay is energized, connections
“
13
”
and
“
14
”
are bridged. For fault the relay is de-
energized (
Diagnostics / faults).
•
When switching off via enable (D1 = Digital In 1), the relay remains energized.

Bypass circuit
Please observe the following during bypass switching (controller shunt with mains voltage):
•
Mutual locking of mains contactor and bypass protection.
•
Time delay of at least 1 second during switching.
•
When the contactor is switched off at the inverter output, the
“
enable
”
(ON / OFF) must also be
opened and closed again when it is switched back on. When switching off, wait at least 90 seconds
before switching back on!
•
Never apply line voltage to the inverter output!

Manual Bypass-Switch type S-D-25 and S-D-50
As accessories are manual main switches with bypass function available.
By switching OFF Frequency inverters necessary waiting period before renewed switching on
amounts minimum 90 seconds!
