2. Maklumat Keselamatan
AMARAN: BAHAYA ELEKTRIK
- Only qualified and trained personnel should install, operate, or maintain this equipment.
- Always disconnect all power sources to the drive and wait for the charge indicator to extinguish before performing any work on the drive or connected equipment. Residual voltage may be present even after power is disconnected.
- Ensure proper grounding of the drive and motor to prevent electrical shock.
- Do not operate the drive with covers removed.
- Protect the drive from moisture, dust, and corrosive gases.
PERHATIAN: KEROSAKAN PERALATAN
- Do not connect the AC power supply to the output terminals (U, V, W).
- Ensure correct wiring and proper terminal connections.
- Sahkan bahawa input voltage matches the drive's specifications (200-220V, 3-phase).
3. Persediaan
3.1 Membongkar dan Pemeriksaan
Carefully unpack the CIMR-7.5G2 drive. Inspect the unit for any signs of physical damage that may have occurred during shipping. If any damage is found, contact your supplier immediately.
3.2 Pemasangan
Mount the drive vertically on a flat, stable, and non-flammable surface. Ensure adequate clearance around the drive for proper ventilation and heat dissipation. Refer to the drive's dimensions for specific spacing requirements. Avoid mounting in direct sunlight or areas with excessive vibration.
3.3 Pendawaian
All wiring must comply with local and national electrical codes. Use appropriate wire gauges for the power and motor connections.
- Grounding (E): Connect the ground terminal of the drive to a reliable earth ground. This is critical for safety.
- Input Power (R, S, T): Connect the 200-220V, 3-phase AC power supply to the R, S, and T input terminals. Ensure the phase sequence is correct.
- Motor Output (U, V, W): Connect the three-phase motor leads to the U, V, and W output terminals of the drive.
- Pendawaian Kawalan: Connect any necessary control signals (e.g., start/stop commands, speed reference, fault outputs) to the designated control terminals. Refer to the terminal diagram on the drive for specific connections.
