  • Page 6: Introduction

    Product Description The E7N Bypass unit provides a means of bypassing the Drive while allowing the motor to operate at full speed, directly from the AC line. It incorporates an AC Drive and two contactor Bypass arrangement in a single UL listed enclosure. The two electrically interlocked IEC rated contactors isolate the Drive from the load when operating in Bypass mode.

    The Bypass unit is thoroughly tested at the factory. Any damages or shortages evident when the equipment is received must be reported immediately to the commercial carrier that transported the material. Shipping damage is not covered by the Yaskawa warranty. After unpacking and inspecting for damage, verify that internal wire connections have not come loose during shipment by spot checking wire terminations with a screwdriver or the appropriate tool.

    Termination Configuration - Power Wiring The input disconnect switch is located in the upper right hand side of the Bypass unit. The three phase input power connection is made to the input terminals of the disconnect. See Figure 2.1 for a representative example. The OverLoad Relay (OLR) is mounted to the contactor assembly or back panel (depending on rating), just above the bypass contactor.

  • Page 34: Field Wiring, Pressure Wire Connector, Wire Type, Range And Tightening Torque Specifications

    Field Wiring, Pressure Wire Connector, Wire Type, Range and Tightening Torque Specifications Determine the wire size for the main circuit so that line voltage drop is within 2% of the rated voltage. Line voltage drop is calculated as follows: IMPORTANT Line voltage drop(V) = √3 x wire resistance (Ω/km) x wire length (m) x current (A) x 10 Prior to removing any protective cover or wiring any part of the Drive, remove all power sources, including main input power and control circuit power.

  • Page 35: Cable Length Between Drive And Motor

    Cable Length between Drive and Motor The Bypass unit should be installed as close as possible to the motor to minimize the length of load side power cable needed between the Drive and the motor. If the cable between the Drive and the motor is long, the high-frequency leakage current will increase, causing the Drive output current to increase as well.

  • Page 36: Grounding

    Grounding Drive and Motor Ground Wire Landing The Drive ground lug (terminal ) is connected to the enclosure. The enclosure ground lug must be connected to earth ground. See Figure 2.1. The Drive has a second ground lug to accept the motor ground lead. Ground Wiring Precautions Observe the following precautions when connecting the ground wire: 208 VAC Drives should have a ground connection with resistance of less than 100 Ω..

  • Page 84: Bypass Unit Start Up Procedure

    BYPASS UNIT START UP PROCEDURE (Please review “Bypass Start Up Preparation” on page 4-4) The front control panel has a digital alpha/numeric display and keypad, in the upper portion, for Drive operation and program- ming. The row of LEDs above the alpha/numeric display indicate Drive operational status. The REMOTE SEQ and REF LEDs in this row are always lit in most Bypass unit applications of the E7 Drive (See Chapter 3 for an explanation).

    Bypass Unit Operation Description (For selector key positions, control inputs and DIP switch selectable functions.) The Bypass has two modes of operation: Bypass and Drive. When in the Bypass mode the connected motor is run directly from the incoming AC line, whereas in Drive mode the motor is run from the Drive output. The DRIVE Select and Bypass Select keys located on the front panel determine the operating mode.

    If a “Stand Alone” Ground Fault Interrupter Operates When the Drive is Run The Drive performs internal switching, so there is a certain amount of leakage current. This may cause an external ground fault interrupter to operate and cut off the power supply. Whenever possible, use a ground fault interrupter with a high leakage detection level (i.e., a sensitivity current of 200 mA or greater per unit, with an operating time of 0.1 s or more), or one that incorporates high frequency countermeasures (i.e., one designed for use with Drives).
