Connecting dry contacts and
communication port (optional)
Determining wiring
Connection operations
Procedure:
wiring is connected via the bottom, in
front of the device.
Signal cable connections must
be mechanically fixed near the
connectors so that any mechanical
stress on the conductors is prevented
configuration of dry contact terminal
block:
2 x voltage-free changeover
switches: conditioner running/stopped,
1 x voltage-free changeover switch:
current-limiting operation;
connection to the terminal block may
be made whilst SineWave™ is operating;
these contacts comply with safe extra
low voltage insulating requirements.
