R-6. Check installed cables for adequate clearance
One inch clearance is required between the underside of inter-connecting cables and the top of all battery
cases across each tier to accommodate the P3300 hold down strut and KYDEX insulating channel.
If this space is not available due to insufficient cable lengths, new cables of the correct length must be installed.
This situation will require replacing existing cables before going to the next assembly operation.

R-8. Install Seismic hold down strut and KYDEX insulator
CAUTION – Avoid shorting battery terminals against hold down strut !!
Repeat this step for each tier.
Place the “U” shaped KYDEX insulating
channel over the “U” shaped Hold down
strut.
Position this assembly so it looks like a
“U”. The KYDEX insulator will now be on
the bottom.
Starting on the lowest tier, at either end of
the rack, slide the hold down strut/insulator
assembly under the inter-cell cables so
that the flat side of the strut assembly rests
CENTERED on top of the battery cases.
