removal, wiring, maintenance, and inspection of the products. Failure
to remove power may cause elec­trical shocks.
• For wiring, use wires of proper size to meet voltage and current
requirements. Tighten the terminal screws to the recommended Housing

Selecting Terminal Blocks by Current According to JIS Standards

IDEC’s terminal blocks are compliant with JIS C 2811. and JIS C 8201-7-1. The current varies depending on the operationg conditions (wire type, number of
budle wire, operating temperature, etc.). See the table below for choosing the terminal block.
When using the terminal blocks as UL, CSA, and TÜV approved products, refer to UL, CSA, and TÜV ratings.

How to read the graph
When using IDEC terminal blocks, make sure that the operating temperature and the temperature of the bus bars do not exceed 100°C.
How­ever, the upper limit of the temperature rise is limited to 45°C by JIS C 2811.
Operating temperature + Temperature rise at bus bars ≤ 100°C
Note: Select wires according to the allowable temperature, operating temperature, and temperature rise of bus bars.
About SCCR of Terminal Block
When exporting machine or systems to the USA, the smallest short-circuit current rating of the control board’s main circuit must be
displayed as SCCR (short-circuit current rating) value. SCCR is specified by UL508A-2001, Supplement SB, Table SB4.1. The value is 10kA
for terminal block.

Crimping Terminals
•• When using crimping terminals, be sure to use insulated terminals to prevent electric shocks.
Without Crimping Terminals
•• Insert the wire until the insulation comes into contact with the terminal metal part. Wire
•• Strip the insulation so that the wire is longer than the width of the wire clamp.
•• When connecting two wires, use wires of the same size.

Notes on Wiring
• Tighten all terminal screws including unused terminal screws.
• Be careful not to drop a terminal block (without an end plate) as the spring may fall out from the housing. Bus Bar

• Tighten the terminal screw to the recommended tightening torque.

Crimp Terminals
• When using crimp terminals, be sure to use insulated terminals to prevent electrical shocks.

Without Crimp Terminals Wire

• Insert wire until the insulation comes into contact with the bus bar.
• Strip the insulation so that the wire is longer than the washer width. (BN1U-16W: approx. 9 mm,
BN1U-20W: approx. 9 mm, BN1U-40W: approx. 11 mm)
• When connecting two wires, use wires of the same size.

Safety Precautions
Notes on Wiring
Crimping Terminals Washer Width Terminal Metal Part
• When using crimping terminals, be sure to use insulated terminals to prevent electric
shocks.
Without Crimping Terminals
• Insert the wire until the insulation comes into contact with the terminal metal part.
• Strip the insulation so that the wire is longer than the width of the wire clamp. Wire
Insulation
• When connecting two wires, use wires of the same length.
• To prevent damage, ensure to use plain washers when installing.

Calculating the Rail Length (When the same type terminal block is mounted)
BDA and BDP Rails Mounting Hole

L1 = 12.5 × N
L2 = L1 – 25
N: Rounded up numerical number from the calculated value of M.
(Example: N for 19.1 is 20)

(A + 0.1) n + 68.5
M=
12.5 L2
L1
A: Thickness of each terminal block
n: The number of terminal blocks
Note: This formula is for calculating the maximum rail length
including tolerance. Depending on the combination of
termi­nal blocks, the required rail length may be shorter
than the calculated value, particularly when many terminal
blocks are combined.

Instructions

Installation of Rail Mount Terminal Blocks When using DIN Rail

1. Determine the length of the DIN rail according to the width of
End Plate the terminal blocks.
2. Assemble the terminal blocks with an end plate on one side,
and then install them onto the DIN rail.
(When mounting BD8, BD7, and BDK5 series on the same DIN
Rail rail, use end plates at the end of assemblies of each series.
3. Install a end clip (BDL11) so that the terminal blocks are
mounted in the center of the DIN rail.
See “Installing the end clip” below.
4. Insert the marking strip and fasten with another end plate.
5. Install the end clip (BDL11) on the other end of the terminal
End Clip block
6. Cover the terminal block with the dust cover.

Installing Surface Mount Terminal Blocks

To install surface mount terminal blocks, use four screws and
tighten four corners of the terminal blocks to a torque of 1.0 N·m
maximum.
For screw types and tightening torque, see the table below. See
Installing and Removing the Marking Strip page 49 for mounting hole dimensions.

Notes on Wiring Washer Width Terminal Metal Part

Crimping Terminals
• When using crimping terminals, be sure to use insulated terminals to prevent electric shocks.
Without Crimping Terminals
Wire
• Insert the wire until the insulation comes into contact with the terminal metal part. Insulation
• Strip the insulation so that the wire is longer than the width of the wire clamp.
• When connecting two wires, use wires of the same size.
