D4BS

8

Operation Key

Make sure that the Operation Key can be inserted properly with

a tolerance of

±0.5 mm in the upward, downward, left, or right

direction. Otherwise the D4BS may soon become damaged due to

misalignment.

Observe the specified insertion radius for the Operation Key and

insert it in a direction perpendicular to the key hole. Do not use the

D4BL operation key.

Changes in Head Mounting Direction

By removing the screws on the four corners of the head, the head can

be reset in any of four directions. The head direction can be changed

with or without the Operation Key inserted in the head. Make sure that

no foreign materials enter through the head and that the head is

tightened securely within the proper torque range.

Wiring

Do not connect the lead wires directly to the terminals. Connect the

lead wires through insulation tubes and M3.5 round crimp terminals.

Tighten each terminal screw within the proper torque range.

Wire using the methods shown below so that the crimp terminals are

not caught on the case or cover. Otherwise it may not be possible to

mount the cover completely and malfunctions may occur.

Conduit Opening

• Tighten the connector to a suitable torque.

• Excessive tightening torque may damage the casing.

• When using 1/2-14NPT conduits, apply sealing tape between the

connector and conduit opening to maintain the degree of protection

(IP67) of the Switch.

• If using a Pg13.5 conduit, use an ABS-08 Pg13.5 connector or an

ABS-12 Pg13.5 connector (manufactured by Nippon Flex).

• Use a connector (SC Series, sold separately) suitable for the outer

diameter of the cable.

• When wiring a 3-conduit model, securely tighten the cap screw

provided for unused conduit openings.
