  • Page 8: Mechanical Installation

    QUICK REFERENCE GUIDE Mechanical installation Drawout case The 469 is packaged in the standard SR-series arrangement, which consists of a drawout relay and a companion case. The case provides mechanical protection for the drawout portion and is used to make permanent electrical connections to external equipment. Where required, case connectors are fitted with mechanisms, such as automatic CT shorting, to allow the safe removal of the relay from an energized panel.
  • Page 9 QUICK REFERENCE GUIDE FIGURE 3: Single and double unit panel cutouts Before mounting the 469 in the supporting panel, remove the unit from the case. From the front of the panel, slide the empty case into the cutout. To ensure the front bezel sits flush with the panel, apply pressure to the bezel front while bending the retaining tabs 90°.

  • Page 10: Unit Withdrawal

    QUICK REFERENCE GUIDE Unit withdrawal Turn off control power before drawing out or reinserting the relay to prevent maloperation! If an attempt is made to install a relay into a non-matching case, the case's configuration pin will prevent full insertion. Applying a strong force in this instance will result in damage to the relay and case.

  • Page 11: Unit Insertion

    QUICK REFERENCE GUIDE Unit insertion To insert the unit into the case: Ensure that the model number on the left side of the relay matches the requirements of the installation. Raise the locking handle to the highest position. Hold the unit immediately in front of the case and align the rolling guide pins (near the hinges of the relay's handle) with the case's guide slots.

    QUICK REFERENCE GUIDE SYSTEM DATA Ground CT: For high resistive grounded systems, sensitive ground detection is possible with the 50:0.025 CT. On solidly grounded or low resistive grounded systems where the fault current is much higher, a 1A or 5A secondary CT should be used. If residual connection is used, pickup levels and timers must be set with respect to the acceleration time.

  • Page 54: Unbalance Alarm And Trip

    SYSTEM DATA QUICK REFERENCE GUIDE Unbalance Alarm and Trip: The unbalance settings are determined by examining the motor application and motor design. The heating effect of unbalance will be protected by enabling unbalance input to thermal memory; described in details in Chapter 5, Thermal Model. A setting of 10% for the Unbalance Alarm with a delay of 10 seconds would be appropriate and the trip can be set to 20% with a delay of 5 seconds.
