Installation guide

11
• Tightening the screws with too much force
can damage the LT unit’s plastic case.
• The necessary torque is 0.5N•m.
• Be sure to insert installation fasteners
in the recessed portion of a installation
fasteners hole. If the fasteners are not
correctly attached, the LT unit may shift
or fall out of the panel.
3. Wiring to the DIO Connector
• Be sure to remove the DIO Connector
from the LT unit prior to starting wiring. Fail-
ure to do so may cause an electric shock.
 Items Required to Wire Connectors
Screwdriver
Recommended type: 1891348-1 <Tyco Elec-
tronics AMP.>
If another manufacturer is used, be sure the
part has the following dimensions:
point depth: 1.5mm [0.06in.]
point width: 2.4mm [0.09in.]
Point shape should be DIN5264A, and meet
Security Standard DN EN60900.
Also, the screwdriver’s tip should be flat as
indicated in order to access the narrow hole
of the connector:
 DIO Cable Specifications
 Connecting the DIO Cable
(1) Insert a flatShead screwdriver, at an angle,
into the tool insertion hole (square-shaped
hole) of the connector.
(2) When inserting the flathead screw driver,
be sure that it is perpendicular to the cen-
ter division wall.
• Make the insertion distance of the flathead
screwdriver approximately 4 mm. Inserting
forcefully may break the inside of the con-
nector and will a cause of contact defect.
Also, do not turn the flathead screwdriver
while the tip is inside of the tool insertion
hole (square-shaped hole).
(3) The adjacent wire insertion hole (round-
shaped hole) will be in an open state.
With the flathead screwdriver still
inserted, insert the wire into the wire
insertion hole (round-shaped hole).
(4) Remove the flathead screwdriver from
the tool insertion hole (square-shaped
hole). The wire insertion hole (round-
shaped hole) will close and the wire will
be secured. In the case of wire removal,
remove the desired wire by inserting a
flathead screwdriver into the correspond-
ing tool insertion hole (square-shaped
hole) following procedures (1) and (2).
(5) Insert the wired DIO connector straight
into the DIO I/F of the LT unit.
• Be sure to strip only the amount of
cover required. If too much cover is
removed, the end wires may short
against each other, or against an elec-
trode, which can create an electric
shock. If not enough cover is removed
the wire cannot carry a charge.
