Case Mounting; Unit Withdrawal And Insertion; Relay Withdrawal - GE 745 TRANSFORMER MANAGEMENT RELAY Instruction Manual

3.1 DRAWOUT CASE
Before mounting the SR unit in the supporting panel, remove the relay portion from its case, as described in
the next section. 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's front while bending the retaining tabs 90°. These tabs are
located on the sides and bottom of the case and appear as shown in the illustration. After bending all tabs, the
case will be securely mounted so that its relay can be inserted. The SR unit is now ready for panel wiring.
