5. Maintenance And Inspection

Preventive maintenance and inspection is required to maintain the MDB-100 Modbus interface in its optimal condition and to ensure a long operational lifetime. Depending on usage and operating conditions, perform a periodic inspection once every three to six months. Before starting inspections, always turn off all power supplies to connected drives, and wait at least five minutes after each drive’s “CHARGE” lamp has gone out.

DANGER! Do not touch any internal parts with power applied to the drives, or for at least 5 minutes after power to the drives has been removed. A hazard exists temporarily for electrical shock even if the source power has been removed.

Inspection Points

•Check that the Modbus network connector screws and terminal block plug are not loose. Tighten if necessary.

•Check that the drive communication cables are not loose. Reinsert if necessary.

•Visually check all wiring and cables for damage. Replace as necessary.

•Clean off any accumulated dust and dirt.

•If use of the MDB-100 is discontinued for extended periods of time, apply power at least once every two years and confirm that the unit still functions properly.

•Do not perform hi-pot tests on the drives or MDB-100 interface, as they may damage the units.

Please pay close attention to all periodic inspection points and maintain a good operating environment.
