LOW SOUND FAN — A shroud and a wire guard provide protection from the rotating fan. The exposed end of the fan motor shaft is protected from weather by grease. If fan motor must be removed for service or replacement, be sure to re- grease fan shaft and reinstall fan guard. The fan motor has a step in the motor shaft. For proper performance, fan should be positioned such that it is securely seated on this step. Tighten the bolt to 15 ± 1 ft-lb (20 ± 1.3 N·m).

IMPORTANT: Check for proper fan rotation (counter- clockwise when viewed from above). If necessary, switch any 2 power leads to reverse fan rotation.

Motormaster® V Controller — The Motormaster V controller is standard on size 010 and 015 units. For other sizes, the optional or accessory Motormaster V controller uses an in- put signal from the AUX board. See Fig. 32. The controller is

factory configured and requires no field programming. If a situ- ation arises where the drive does not function properly, the in- formation provided below and in Table 38 can be used to trou- bleshoot the drive.

WARNING

Hazard of electrical shock. Wait three minutes after discon- necting incoming power before servicing drive. Capacitors retain charge after power is removed. Drive assembly includes externally mounted current limiting resistors. Use extreme caution when servicing the drive. Failure to com- ply could result in possible personal injury.

When configured as shown in this literature, this equip- ment is designed to start when it receives line power. Ensure that all personnel are clear of fans and guards are installed before applying power. Failure to comply could result in possible personal injury.

CAUTION

DO NOT connect incoming AC power to output terminals T1, T2, and T3. Severe damage to the drive will result. Do not continuously cycle input power to the drive more than once every two minutes. Damage to the drive will result.

CAUTION

If input power has not been applied to the drive for a period of time exceeding three years (due to storage, etc.), the electrolytic DC bus capacitors within the drive can change internally, resulting in excessive leakage current. This can result in premature failure of the capacitors if the drive is operated after such a long period of inactivity or storage. In order to reform the capacitors and prepare the drive for operation after a long period of inactivity, apply input power to the drive for 8 hours prior to actually operating the motor. Before attempting to operate the drive, motor, and driven equipment, be sure all procedures pertaining to installation and wiring have been properly followed. Fail- ure to comply could result in equipment damage.

GENERAL OPERATION — The speed varies in proportion to a 4 to 20 mA signal produced by the ComfortLink™ con- trols. The MMV output speed is displayed in Hz.

The ComfortLink controls must be configured for MMV operation in order for it to operate. This is configured under the Configuration menu (Configuration→MM→MMR.S) and
