12 Put the lug aside and fully cover the bare wire with anti-oxidizing grease
or equivalent if your local electrical code allows it.
13 Crimp the lug firmly onto the cable.
14 Wipe off the excess grease and wipe the lug clean.
15 Wrap electrical tape over the joint between the barrel and the insulation.
16 When the power input cable is less than 1/0 AWG (53.49 mm
2
), wrap
electrical tape around the cable where the neck of the insulation boot will
reside. Wrap enough tape to snugly close the gap.
17 Permanently label the cable near the lug as B1+. Position the label so it
can be easily read and traced to termination after all cables are installed.
After the first cable, label the others according to the figure “Overhead
power input cables for the lower shelf connected to the BIP” (page 337).
18 Put the lug of the cable onto the studs, barrel at the bottom, and flush
against the rear of the BIP.
19 Put a Belleville washer back onto each stud, convex upwards. The high
part of the washer must be furthest from the lug.
20 Finger-fasten the nuts back onto each stud. The nuts thread easily, so if
there is resistance, check
• that the thread pitch of the nut matches the thread pitch of the stud
(since the 2 studs may have different pitches)
• that you are not cross-threading
CAUTION
Risk of damage to power connections
The metal of the top stud of each pair is softer than the
bottom stud because of increased electrical conductivity.
Ensure that you do not overtighten either stud, nor leave
one too loose. Damaging a stud means its BIM cannot be
powered up until the BIP is replaced.
