6.3REPLACING FUSES

WARNING:

Be sure to replace fuses with the correct type and rating, specified in Table 4.

Always replace fuse F3 with a 2 A fast blow type as serious injury could result from the wrong fuse. Open the case and remove the PCB (refer to § 6.2)

Note: A limited number of MR810AEA units were manufactured with fuse F3 rated at 1.5 A. These units can be identified by the fuse rating information laser-scribed on the inside of the lower case. For these units only, F3 must be replaced with a 1.5 A fast blow fuse.

1.Slide the cable clamp up out of the transformer mount and lift it away from the fuses.

2.The fuses can now be accessed. Refer to Figure 6.3 for the location of the fuses and Table 4 for replacement fuses.

3.Install the PCB and assemble the case (refer to § 6.8).
