6. Installation & Maintenance

Installation Recommendations

• Rack Installation: Strictly follow Bently Nevada’s installation manual for rack welding and slot fixing to ensure the module is firm.
• Power Connection: Use 3500/15 (AC) or 3500/15 (DC) power module to supply power to it, and the power wiring must comply with standards.
• Probe Wiring: According to monitoring needs, correctly connect vibration sensors (such as accelerometers) to the corresponding input channels.

Maintenance Points

• Regular Inspection: Regularly check whether the terminal blocks are loose and whether the rack locking device is effective.
• Protection Inspection: Check whether the O-rings and seals are intact to prevent dust and moisture from entering.
• Firmware Upgrade: Regularly upgrade the module firmware according to system prompts to maintain compatibility with the latest diagnostic software.
