Create a slot of dimensions as shown in Figure 1-2 to house therelay in the protection panel.2. Flush the rear-side of relay into the protection panel cut-out.3. Fasten the relay using the four M4x20 Pan Phillips SS screws withnut provided in the 7SR45 self powered overcurrent and earthfault relay packing box to the protection panel/cubicle.4. Carry-out all other installation steps/wiring internally from theprotection panel.5. In the rear terminal of the relay, execute the wiring process asmentioned in scheme requirements. For more details aboutterminal connector diagram, refer to, Figure 1-3.Refer to Table 1.1 for the recommended terminal lugs to be used.If needed, use washers from the kit to connect the current inputsto X5 terminal.6. The earthing cable should be wired as indicated in the Figure 1-3using a non-stranded cable of 2.5/4 mm 2 and this should beterminated in the shortest possible path to the earth terminal/busbar in panel or cubicle.7. Maintain a minimum clearance from the relay as given in Figure 1-1to ensure safety and accidental touch of terminals. In case ofwork area is restricted in a cubicle, then suitable protectiveterminals to be provided in the cubicle.CommissioningProceed the commissioning tests if the following criteria's are satisfied:1. Equipment has not been damaged in transit (physical damage).2. Equipment has been correctly connected and installed.3. Remove the gland insulator from the battery compartment.4. Characteristics of the protection and settings which are based oncalculations.5. Confirm that settings have been correctly applied.6.
