VII. Installation and Maintenance Instructions

Installation and Power On

Disconnect the card when power is off, ground the chassis; Power on, self-check by NI-DAQmx, preheat for 15 minutes.

Operating Temperature: 0–55℃. Keep the air duct unobstructed and avoid blocking the fan.

Wiring and Operation

Analog input uses differential shielded cables to reduce common-mode interference; Input voltage ≤ ±10 V.

Avoid frequent plugging and unplugging of 37-pin interface; It is recommended to use CB-37 wiring box; Pay attention to level matching for digital I/O.

Isolation Area and Non-Isolation Area Wiring are separated to avoid high voltage entering the control side.

Daily Maintenance and Calibration

It is recommended to conduct traceability calibration once a year; Built-in self-calibration compensates for temperature drift.

Keep the interface clean, prevent dust accumulation during long-term inactivity; Stay away from strong vibrations and condensation.
