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.
The proper lead wire is AWG20 to AWG14 (0.5 to 2.5 mm
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.
