When using bare ferrules or bare blade terminals, make sure that an
insulation sheath is applied.
• If stranded wires are connected without ferrules or blade terminals,
make sure that wires are not separated.
• When tightening the terminal screw while holding the terminal block
in the hands, be careful not to injure your fingers with the tip of the
screwdriver.

BY9Z-SQV jumper is exclusive for BY1S standard terminal blocks and
cannot be used for ground terminal blocks.
Connecting and removing wires
1. 2. Insert an applicable screwdriver to the square hole 1 in an angle
all the way to the end to open the spring inside the terminal block.
Make sure to use an applicable screwdriver and insert it to the
square hole 1 where the wire needs to be connected.
Do not add excessive force to the spring when inserting the
screwdriver. The spring may be deformed.
3. With the screwdriver inserted, insert an applicable wire (stranded,
solid) with the insulation removed to the standard length, or a wire
crimped with ferrule or blade terminal, all the way to the end in
round hole 2 . Note that only a single wire, ferrule, or blade terminal
can be connected to a single round hole 2 .
4. Pull out the screwdriver. Make sure that wiring is properly connected
by pulling the wires lightly.
• To remove a wire, insert an applicable screwdriver to square hole 1
all the way to the end to open the spring. After removing the wire,
ferrule, or blade terminal, remove the screwdriver.
Do not add excessive force to the spring. The spring may be de-
formed.
• If two wires are connected to a single round hole 2 make sure to
use a recommended ferrule or blade terminal that allow two wires to
be inserted.
Make sure to use an applicable wire with insulation removed at the
standard length, ferrule, or blade terminal for wire connection. Use of
inappropriate wires, ferrules, or blade terminals may cause heating
and fire.

![Installing and Removing Accessories
1) Installing and removing end stops
BY9Z-KEW35/2, BY9Z-KEW35/1
• The applicable rail is a 35mm-wide DIN rail (BAA1000, BAP1000).
• With the mounting screw at the center of the end stop loosened,
install the end stop by hooking the mounting hook to the DIN rail and
pushing down the other hook from the top.
• The end stop will be secured by tightening the mounting screw on the
center.
Make sure to tighten the mounting screw at the recommended
tightening torque.
Recommended tightening torque
BY9Z-KEW35/2: 0.5 to 0.7 N·m
BY9Z-KEW35/1: 0.8 to 1.15 N·m

Failure to remove power may cause electrical shock, fire, or malfunction. • For wiring, use wires of proper size to meet voltage and current requirements. • Make sure that terminal blocks and wires are connected securely. Otherwise, abnormal heat may be generated and cause fire. • Make sure that cut wire ends and chipping from drilling do not enter into the inside of the product at the time of installation and wiring. Cut wire ends and chipping inside the product may cause fires, failures, and poor conductivity. • Make sure to use under the voltage and electric current suitable for terminal blocks. Using under incorrect voltage and electric current may cause fires and failures. • Do not apply excessive load or shock to the terminal block. Other- wise damages may occur. • Do not apply excessive shock to the connected wires. Otherwise, terminal blocks may be damaged and cause conduction failure. • Do not use in places where the terminal blocks are subject to salt contaminated water, oil, and chemicals. DIN Rail Mounting • Use 35mm-wide DIN rail (BAA1000 or BAP1000) when mounting BY1K or BY1S standard terminal blocks. • When the BY1K and BY1S ground terminal blocks are mounted on the 35mm-wide DIN rail, the conductive metal inside the terminal blocks will come in direct contact with the DIN rail, enabling easy ground connection. Therefore, make sure that the DIN rail is made of steel (BAP1000). Mounting on alumite coated DIN rail (BAA1000) may cause poor conductivity. Contact part Contact part Conductive metal DIN rail (steel) • BY1K and BY1S ground terminal blocks can be used as a protective conductor (PE function) by connecting to a 35mm-wide steel DIN rail (BAP1000) but cannot be used as a PEN function conductor. • See page 2 for BY1K internal connection diagram. See page 6 for BY1S internal connection diagram. Installation BY1K and BY1S Standard Terminal Blocks BY1S Ground Terminal Block • Install the end stop on one side of the DIN rail. • Install the terminal block to the DIN rail, ensuring there is no gap. To install the terminal block, attach the fixing hook to the side of the DIN rail and push the other side (removing hook side) to mount on the DIN rail. Make sure that excessive force is not applied to the terminal block. Note that the front and back sides of the terminal block are correctly mounted so that the metal parts visible from the open side of the terminal block do not contact each other. • Be sure to install an end plate when using a terminal block with an open side that has metal parts. Push Fixing hook Removing hook DIN rail Attach the fixing hook side of the terminal block to the rail. • If the terminal block requires an end plate, install the end plate and secure with a end stop. If the terminal block does not require an end plate, simply install an end stop. • If terminal blocks of different sizes are mounted on a single rail, install an end plate on the open side of the terminal block to hide the internal metal parts. • To remove the terminal block, insert a screwdriver between the removing hook and push up. Note that using a screwdriver with anti-slip coating on the tip will make the terminal block easier to remove. Make sure that excessive force is not applied when removing the terminal block. Removing the terminal block with excessive force applied on the top may cause deformation or damage to the removing hook. • Installation and removal of terminal blocks to and from DIN rails should take place in an environment of 0˚C or higher. Installation and removal in low temperatures (below 0˚C) may cause damage to the removing hook.

To mount, loosen the mounting screw at the center of the ground terminal block and mount on the DIN rail. Check that the joint of the ground terminal block is securely attached to the DIN rail. Make sure that the ground terminal block is correctly mounted on the DIN rail. Otherwise, heating or fire may occur. DIN rail (steel) DIN rail (steel) Tighten the mounting screw. Make sure that the terminal block is secured to the DIN rail. Mount the terminal block on the DIN rail. • Tighten the center mounting screw of the ground terminal block using the applicable tool mentioned in table 1. Tighten at the recommended tightening torque. If the tightening torque is insufficient, heating or fires may occur. • To remove, loosen the center mounting screw of the ground terminal block. Make sure that the mounting screw is fully loosened before removing. Removing forcibly may cause deformation or damage to the terminal block. Wiring BY1K Screw Clamp Terminal Blocks • Stranded wires, solid wires, and stranded wires with ferrules or blade terminals can be connected to BY1K screw clamp terminal blocks. • Tighten the terminal screw to the recommended tightening torque using the applicable tool mentioned in table 2. • Use commercially available ferrules and crimping tools. When using ferrules or blade terminals, see table 3 for dimensions for recommended ferrules or blade terminals. 13 BY Series Terminal Blocks (Instructions)
