Routine Maintenance and Repair
DC590+ DRV Series DC Digital Drive
IMPORTANT
When re-assembling the unit, apply a `zinc-loaded’ jointing compound between the fuses and busbars, and between the
busbars and phase assemblies (BICC BX1 - Parker SSD Part No. EA466241)
Observe all tightening torque levels, refer to Appendix E: “Technical Specifications” - Termination Tightening Torque (Frame 7).
Bench-Top Replacement Procedure
1.
Disconnect the relevant fuse microswitch assembly by unplugging the lead assembly from the rear trunking.
2.
Remove the M12 (A).
3.
Loosen (but do not remove) the four M10 screws (B, C, D, E).
4.
Hold the fuse assembly handle in one hand and remove the two screws (D, E) from the lower phase assembly.
CAUTION: The fuse assembly weighs 9kg maximum.
5.
Hold the fuse assembly handles and remove the two screws (B, C) from the upper phase assembly.
6.
With the fuse assembly on the bench, remove the M12 screws (F, G, H, I) holding the fuses to the busbars
. Take a note of the fuse microswitch
position on the fuse assembly,
do not forget, as the lead assembly will not fit if mounted in the wrong position.
Reverse the above procedure for replacement. Remember to re-connect the fuse microswitches.
In-Situ Replacement Procedure
1.
Disconnect the relevant fuse microswitch assembly by unplugging the lead assembly from the rear trunking.
2.
Remove the M12 screw (A), and the 4 screws (F, G, H, I). Remove the CT plate and handles.
3.
Remove the relevant screws (B, C or D, E) and lift the fuse busbar assembly from the phase assembly.
4.
Replace the fuse on the busbar and re-connect the microswitch. Fully tighten the fuse to the busbar.
5.
Fit the fuse busbar assembly on to the phase assembly. Don’t fully tighten the screws yet.
6.
Position the CT plate on top of the fuses. The slack in the fuse busbar assembly will allow the fixing holes to be aligned. Insert the screws.
7.
Fully tighten all screws (including those in 5 above).
8.
Re-connect the fuse microswitches.
