Switch S3: Digital input configuration setting (voltage/non-voltage signals)
Depending on the BMS digital input (DI) configuration, switch S3 on the CZ-CAPBC2 interface can
be set for the digital input terminals to accept either non-voltage signals from dry contacts (factory
default: "NON VOLTAGE") or 12 – 24 V DC signals ("VOLTAGE").
