Instructions
Wiring Touch-Down Terminal Blocks: BNH Series
Instructions Step 1 Step 2 Step 3 Step 4
Step 1. Insert the wire (or crimping terminal) into the
terminal block with the terminal screws in the open
position. (Use of crimping terminals is optional.)
Step 2. Push the terminal screw down to hold the wire in
place.
Step 3. Hold the terminal screw down, and tighten with a
screwdriver.
Step 4. To remove the wire, loosen the terminal screw and
pull up until wire is released.
Installation and Removal of Terminal Blocks
Instructions Appearance
Step 1. Slide the terminal blocks onto the DIN rail from one end.
Step 2. Use BNL5 or BNL6 end clips to secure the terminal block
row and to prevent side-to-side movement. BNH10W,
BNH15MW, BNH15LW, and BNH30W can be installed
from the middle of a DIN rail.
Step 3. To install, place the terminal block on top of the DIN rail
and push down until both edges of the terminal block
snap onto the DIN rail.
Step 4. To remove the terminal block, use the BND2 removal tool
as shown on the right.

Mounting Double-Deck Terminal Blocks
Instructions Appearance
DIN Rail Mount:
Step 1. First install the end plate. Then mount the terminal blocks
onto the DIN rail.
Step 2. To prevent side-to-side movement on the DIN rail, use the
BNL-8 mounting clip at both ends of the rail.
Panel Mount:
Step 1. Assemble a row of terminal blocks with end plates on
exposed end(s).
Step 2. Use BNDL2 mounting clips at both ends of a row.
Step 3. With the two holes of the mounting clip aligned with
the terminal block holes, insert a connecting rod through
each hole.
Step 4. Secure the ends of the connecting rods with the connect-
ing nuts, as shown below.

Step 1. Add widths of all terminal blocks
(reference pages 864 through
869).
Step 2. Add the endplate thickness (usu-
ally only one).
Step 3. Add the DIN rail stop widths
(usually two are used).
Step 4. Round to the nearest 2” (50mm)
increment to allow for DIN rail
hole spacing.
Step 5. Add 1” (25mm) to ensure 0.5”
(12.5mm) of clearance at each
end of the DIN rail.
