Installation
PROCEDURE FOR CONNECTING CABLE
The following procedure is recommended so that the D4BL can be
wired or connected to the Indicator Units with ease.
Recommended connecting cable:
AWB20 to AWG18 with seven conductors
A UL2464-style cable is recommended.
Apply sealing tape to the cable and conduit opening so that the
D4BL can conform to IP67. Tighten the connector to a torque of 1.8
to 2.2 Nm (15.93 to 19.47 in lbs).
Connect the Indicator Units to the D4BL after connecting the 7-con-
ductor cable to the D4BL.

connected in sequence beginning with the terminal nearest to
the conduit opening.

The wire leads must be wrapped around the screws clockwise.
Tighten each screw to a torque of 0.5 to 0.7 Nm (4.43 to 6.20 in lbs).
2. The external insulation sheath of the 7-conductor cable must
contact with side A or B as shown in the above D4BL
illustration.

Precautions
MOUNTING
Be sure to install a stopper as shown in the following illustration
when mounting the Safety-door Lock Switch. The range of space “a”
must be determined according to the available set zone 4 mm (0.16

HEAD DIRECTIONS
The head can be mounted in four directions. To remove the head,
turn the head by 45°as shown in figures A and B below.
To change the direction of the head, make sure that the protruding
part of the rotating lever engages with the groove of the plunger.
Then turn the head clockwise or counterclockwise to the desired
direction. At that time, make sure that the groove of the plunger is
located under the rotating lever. If the direction of the head is not set
when the plunger is rotated by 45°, the groove of the plunger pres-
ses the rotating lever. The head, plunger, or the built-in switch may
be damaged as a result.

Be sure to check the mechanical lock and solenoid release func-
tions when mounting the D4BL.
If the head direction is changed, recheck the tightening torque of
each of screw. Make sure that no foreign materials will penetrate
through the key hole on the head.
DEDICATED RELEASE KEY
The dedicated release key, which is provided with the D4BL, is used
to unlock the protective door in case of emergency or power failure.
To open the protective door, insert the dedicated release key and set
the key lock to UNLOCK.
Release key
UNLOCK
LOCK
If the key lock is set to UNLOCK, when the protective door is closed
and people are doing preparation work on the machine inside, the
protective door will not be locked and the machine will not start
operating.
Use the release key to set the key lock to LOCK.
Do not use the release key to start or stop the machine.
This key lock must be normally set to LOCK and sealed with a rub-
ber cap in order to conform to IP67 requirements.
The dedicated release key should be kept only by the person in
charge.
If necessary, to prevent easy access to the dedicated release key,
seal the key lock using a suitable sealing wax. Be careful not to dam-
age the key lock when breaking the seal between the rubber cap
and the key lock.
A cover can be attached to the D4BL. Before attaching the cover,
make sure that the key lock is set to LOCK.
OPERATION KEY
The D4BL is provided with a shock absorptive damper when
shipped attached to the D4BL in order to prevent the D4BL from be-
ing damaged if it is dropped accidentally. Be sure to remove the
shock absorptive damper after the D4BL is mounted.
Do not impose excessive force to the Operation Key in the switch or
drop the Operation Key, or the Operation Key may be deformed or
damaged.
Dropping
Do not operate the Safety-door Lock Switch with a tool other than
OMRON’s special Operation Key for the Safety-door Lock Switch,
otherwise the Safety-door Lock Switch may be damaged or the
safety of the system will not be assured.

OTHERS
When connecting lead wires with crimp-style terminals to the built-in
switch terminals, do not impose excessive force on the crimp-style
terminals.
Each crimp-style terminal must be connected in the direction as
shown in the following illustrations and the crimp-style terminal must
not be on the case or cover.
