• the rail is horizontal
• the labels on the terminal blocks face you
• the connected cables point downwards
4 Have a helper hold the assembly behind the BIP where the strain relief bar
was.
5 For the ETSI assembly only, locate the terminal block on the right end.
Fasten the 2-hole lug of the middle cable to the grounding strip using the
provided screws or green screws. Bend the cable in a loop to the right so
that the barrel side of the lug points to the right. Refer to the figure “The
ETSI power-and-ground assembly A0834149” (page 494).
6 Repeat step 5 for the remaining middle cables of each ETSI terminal
block set. Work from 1 end to the other for ease of access. Fasten all 4
ground cables even if the frame houses only 1 switch.
7 Press your finger along the silvery grounding strips at the top left and right
rear of the frame uprights so that dimples appear to indicate where the
screw holes are located. The uprights are indicated in the figures “The
polyvalent power-and-ground assembly A0834143” (page 493) and “The
ETSI power-and-ground assembly A0834149” (page 494).
8 Using the provided 10-mm (3/8-in.) screws, fasten the rail to the uprights
at the top or second dimple (or hole) from the top of each upright. Tighten
to snug plus a 1/4 turn.
9 On the rear of the BIP, loosen the clamp of the rightmost insulation boot
by using a medium Pozidriv bit that fits snugly. Loosen the clamp until you
can pivot it easily with your finger. The clamp may already have been
loosened.
WARNING
Risk of injury or equipment damage by electricity
Any feed cable that is connected to the rear of the BIP
must be shielded by the provided insulation boot. If you
strip the head of the screw that fastens the clamp against
the boot, you cannot fasten the boot securely to the BIP.
You must not operate the BIP unless you replace a stripped
screw to secure the boot.
