Isolation testing
The following isolation test should be done on the SBR1 rack to
verify proper frame grounding insulation:
1 Connect the negative lead of the DVM to the anchor bolt, and
connect the positive lead to an unpainted surface within the rack, as
shown in the following figure:
2 Measure the isolation resistance.
3 The isolation resistance should be higher than 20M ohms (infinite)
when it is tested by the DVM.
4 If the isolation measurement result shows a value less than 20M
ohms, repair or adjust the anchor bolts, fiber mounting spacer, and
rack position.
