    DD.Z1.1.F1.01 Bypass Enclosures All Z1000 Bypass units are intended for non-hazardous locations. All Z1000 Bypass units are NEMA Type 1 Enclosures and are constructed for indoor use to provide a degree of protection against incidental contact with enclosed electrical equipment and falling dust or dirt.

  • Page 31: Bypass Component Descriptions

    Figure 1.4 Disconnect Handle Shown in the OFF position Contactors The Z1000 Bypass is a 2-contactor or 3-contactor bypass circuit employing IEC rated contactors in an electrically interlocked arrangement to allow mutually exclusive operation in Drive or Bypass modes. The control logic and “soft start” characteristic of the drive limit the drive input and output contactors to motor FLA current or less.
  • Page 32 Control Power Transformer A Control Power Transformer (CPT) is provided to power the Z1000 Bypass 120 Vac control circuit. The VA capacity is determined by the control circuit and optional functions specified for the unit. The CPT primary is fused in both legs, the secondary is fused when required by NEC (transformer VA and wire size dependent).
