    General Safety Information Only qualified personnel should install this array. Personnel should have a clear understanding of these instructions and should be aware of general safety precautions. Improper installation can result in electric shock, possible injury due to coming in contact with moving parts, as well as other potential hazards. If more information is needed, contact a licensed professional engineer before moving forward.
  • Page 3 Inspection & Maintenance during Storage While in storage, inspect array once per month. Keep a record of inspection and maintenance performed. If moisture or dirt accumulations are found on parts, the source should be located and eliminated. At each inspection, rotate the wheel by hand ten to fifteen revolutions to distribute lubricant on motor. Machined parts coated with rust preventive should be restored to good condition promptly if signs of rust occur.

    Electrical Connections Before electrical connections are made, the supply voltage, phase and ampere capacity must be checked for compatibility with the fan motor. In addition, the supply wiring must be properly fused and conform to local and national electrical codes. If the unit is supplied with a safety disconnect switch, ensure proper wiring to the fan motor.

  • Page 22: Vibration

    • For rigidly mounted fans, recommended in-situ vibration velocities of less than .250 in./sec in accordance with AMCA 204 and BV-3 grades. Vibration Measurement on MOA Fan Array An appropriate method is measurement at the motor fastening diameter on the motor support plate in the direction of the motor axis of rotation and perpendicular to this.
