34593 BNC
feedthrough
panels can be supplied
with
different

for
complete information
on
cabling a cable
or
bulkhead ter-
min'tl block.
The
section titled "Connecting Terminal Blocks
to
Modules" also
describes how you
connect
terminal blocks
to
feedthrough panels since
the
panel
connectors are the same
as
module connectors.
The
HP
34594A and
Bare
low-frequency feedthrough panels.
They
have DIN
connectors which mate
to
terminal blocks
from
outside
the

connects
to. For
the
screw-terminal
connectors,
you
first in-
stall connector labels
as
described in
the
section titled "Installing Screw-Terminal
