Therefore, it is necessary to reduce motor load as speed is decreased. Note: Some fan-cooled motors can be used over a wider speed range. Consult the motor manufacturer for details. WARnInG! Some motors have low speed characteristics which cause overheating and winding failure under light load or no load conditions. If the motor is operated in this manner for an extended period of time, it is recommended that the unloaded motor current be checked from 2 15 Hz ( RPM) to ensure motor current does not exceed the nameplate rating. Do not use motor if the motor current exceeds the nameplate rating. 20 21 It is recommended that the drive be used with Inverter Duty or TEnV motors. Inverter duty and most totally enclosed nonventilated (TENV) motors can provide full rated torque over an extended speed range without overheating. See Figure 5. If external fan cooling is provided, open ventilated motors can also achieve an extended speed range at full rated torque. A box fan or blower with a minimum of 100 CFM is recommended. Mount the fan or blower so the motor is surrounded by the airflow. See Figure 6. Maximum Allowed Motor Torque () FIGURE 5 MAXIMUM ALLOWED MOTOR TORQUE VS. The CL Trimpot is used to recalibrate the drive current from 60 thru 200. The Power Start circuit provides an overshoot function that allows most motors to develop more than 200 of starting torque and breakdown torque. Standard I 2 t is undesirable because it causes nuisance tripping. It allows a very high motor current to develop and will turn the drive off after a short period of time. KB s RMS Current Limit Circuit avoids this nuisance tripping while providing maximum motor protection. If the motor is overloaded to 120 of full load (75 of the CL setting), the I 2 t Timer starts. If the motor continues to be overloaded at the 120 level, the timer will shut down the drive after 30 minutes. WARnInG! Disconnect main power before removing or installing the finger-safe Cover. WARnInG! To prevent accidental contact with high voltage, it is required that the finger-safe Cover be properly installed onto the drive after all wiring and setup is complete. It offers protection against electric shock which limits the potential liability to the equipment manufacturer and installer. 22 23 5.1 Removing the finger-safe Cover The Finger-Safe Cover may have to be removed before wiring the drive or setting selectable jumpers. All trimpots can be readjusted with the Finger- Safe Cover installed. Notice the orientation of the Finger-Safe Cover before removing it.

For Reverse Speed Operation, install the jumper in the R position. This drive must be mounted in an enclosure. Care should be taken to avoid extreme hazardous locations where physical damage to the drive can occur due to moisture, metal chips, dust, and other contamination, including corrosive atmosphere that may be harmful. See Safety Warning on pages 8 and 9. To prevent accidental contact with high voltage, it is required that the finger-safe Cover be properly installed onto the drive after all wiring and set up is complete. Do not use this drive in an explosionproof application. 27 28 Application note The enclosure should be large enough to allow for proper heat dissipation so that the ambient temperature does not exceed 45 C (113 F). Leave enough room to allow for AC line, motor connection, and other wiring that is required. See Figures 2A, 2B, 3A and 3B, on pages When mounting the Main Speed Potentiometer, be sure to install the insulating disc between the potentiometer and the panel. 8 RECOMMEnDED HIGH VOLTAGE DIELECTRIC WITHSTAnD TESTInG (HI-POT TESTInG) Testing agencies such as UL, CSA, etc., usually require that equipment undergo a hi-pot test. In order to prevent catastrophic damage to the drive, which has been installed in the equipment, the following procedure is recommended. A typical hi-pot test setup is shown in Figure 15, on page 29. All drives have been factory hi-pot tested in accordance with UL requirements. Warning! All equipment AC line inputs must be disconnected from the AC power. 8.1 Connect all equipment AC power input lines together and connect them to the H.V. lead of the Hi-Pot Tester. Connect the RETURN of the Hi-Pot Tester to the frame on which the drive and other auxiliary equipment are mounted. 8.2 The Hi-Pot Tester must have an automatic ramp-up to the test voltage and an automatic ramp-down to zero voltage. Note: If the Hi-Pot Tester does not have automatic ramping, then the hi-pot output must be manually increased to the test voltage and then manually reduced to zero. This procedure must be followed for each machine being tested. A suggested Hi-Pot Tester is Slaughter Model CAUTIOn. Instantly applying the hi-pot voltage will cause irreversible damage to the drive, which will void the warranty. 29 FIGURE 15 TYPICAL HI-POT SETUP High Voltage Dielectric Withstand Tester (Hi-Pot Tester) LEAKAGE AC KILOVOLTS 0mA 10mA RETURN TEST VOLTAGE H.
