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
Chapter 1 — Receiving and InstallationBulletin No. 50006-519-01BMounting in General Purpose Metal Enclosure December 1996• Verify that the voltage and frequency characteristics of the input line match thedrive controller nameplate rating.• Installation of a disconnect switch between the input line and drive controlleris recommended. Follow national and local codes.• Overcurrent protection is required. Install line power fuses (F1-F3)recommended in Table 11 on page 30 and Table 13 on page 31.• Turn off all power before installing the drive controller. Place a “DO NOTTURN ON” label on the drive controller disconnect. Before proceeding withinstallation, lock the disconnect in the open position.• The ATV56U41N4 to ATV56D79N4 and ATV56U41M2 to ATV56D46M2 drivecontrollers may be mounted inside another enclosure to increase the degree ofprotection or size of the enclosure. See “MOUNTING INGENERAL PURPOSE METAL ENCLOSURE” on page 10 and “MOUNTINGIN TYPE 12 (IP54) METAL ENCLOSURE” on page 12.• To improve ventilation, the front cover may be removed when mounting thedrive controller in an enclosure. For ATV56U41N4 to D23N4 andATV56U41M2 to ATV56D16M2 drive controllers, the front cover is removedby first opening the cover, then separating the retaining clips on the cover fromthe side panel. For ATV56D33N4 to D79N4 and ATV56D23M2 toATV56D46M2 drive controllers, the front cover is removed by first opening thecover, then lifting it vertically.• With the front cover removed, the ATV56U41N4 to D79N4 and ATV56U41M2to ATV56D46M2 drive controllers have an IP20 enclosure rating.• The solid state switches of the drive controller power circuit do not providecomplete isolation from the line. Leakage currents and voltages may bepresent at the U/T1, V/T2, and W/T3 terminals of the drive controllerwhenever power is present.MOUNTING INGENERAL PURPOSEMETAL ENCLOSUREVentilationThe ALTIVAR 56 drive controller is a Type 1/IP30 enclosed product. However,certain application considerations may require that the drive controller be installedinside a larger enclosure. If so, observe the following precautions:Forced air cooling is provided on all drive controllers. A fan is located in thebottom of the drive controller (see Figure 6 on page 11) and is protected by aperforated cover. The fan draws in ambient air from underneath or from the frontof the enclosure over the heat sink fins, and expels it vertically from the top of theenclosure. When mounting the drive controller, be sure the air inlets and outletsare not obstructed.• Follow the installation precautions on pages 9 and 10.• Observe minimum clearance distances as indicated in Figure 5 on page 9.• If the enclosure does not provide sufficient free air flow, an enclosureventilation fan is required to exhaust the heat to the enclosure outside ambient.The enclosure fan should have a greater fan flow rate than the drive controllerfan flow rate listed in Table 6 on page 11.• If there is a possibility of condensation, keep the control supply switched onduring periods when the motor is not running or install thermostaticallycontrolled strip heaters.10 © 1996 Square D All Rights Reservedηττπ://νιχοντρολσ.χοm
