Bulletin No. 50006-519-01BDecember 1996Chapter 1 — Receiving and InstallationInstallation PrecautionsPrior to installation:1. Open the drive controller door or remove access covers.2. Visually verify that all internal mounting hardware and terminal connectionhardware is properly seated, securely fastened and undamaged.3. Visually verify that the control board is properly seated, securely fastened andundamaged. Verify that internal wiring connections are tight. Inspect allconnections for damage.4. Close and secure the drive controller door or replace access covers.CAUTIONEQUIPMENT DAMAGE HAZARDDo not operate or install any drive controller that appears damaged.Failure to follow this instruction can result in injury or equipment damage.INSTALLATIONPRECAUTIONSTo avoid equipment damage, follow these precautions when installing the drivecontroller:• Electrical current through drive controller will result in heat losses that mustbe dissipated into the ambient air immediately surrounding the drivecontroller. To prevent thermal fault or equipment damage, provide sufficientenclosure cooling and/or ventilation to limit the ambient temperature arounddrive controller to a maximum of 40 °C. For power dissipation, refer to Tables1 through 4 on pages 3- 4. Minimum clearances required around the drivecontroller for unobstructed air flow are shown in Figure 5. For proper thermaldissipation, the minimum enclosure size must not be based on clearancesalone. Refer to section “MOUNTING IN GENERAL PURPOSEMETAL ENCLOSURE” on page 10 for additional information.8 (200)Dimensions: in (mm)4(100)2(50)2(50)2 2(50) (50)4 (100)8 (200)Outlines 1-3 Outlines 4-5(ATV56U41N4 to D23N4 andATV56U41M2 to D16M2)(ATV56D33N4 to D79N4 andATV56D23M2 to D46M2)Figure 5: Clearances for Drive Controllers• Mount drive controller vertically.• Do not locate drive controller near heat radiating elements.• When installation surface is uneven, put a spacer behind the drive controllermounting pads to eliminate gaps. The drive controller exterior may bedamaged if fastened to an uneven surface.• Drive controllers are Type 1 enclosed devices and must be installed in asuitable environment. The environment around drive controller must notexceed Pollution Degree 3 requirements as defined in NEMA ICS 1 or IEC 664.© 1996 Square D All Rights Reserved9ηττπ://νιχοντρολσ.χοm
