Mounting the Amplifier and Wiring
■ Mounting the amplifier
● DIN rail mounting type (Main unit)
This section describes how to mount the DIN rail mounting type: GT-
71A/71AP (Main unit).
1
Fit the tab of the lower part of the
main unit to the DIN rail. While
inserting the main unit in the
direction of Arrow (1), push the body
down in the direction of Arrow (2).
2
To detach the amplifier, while
pushing the main unit in the
direction of Arrow (1), pull the body
up in the direction of Arrow (3).
When using a fixture (OP-76877), mount as shown below.
● DIN rail mounting type (Expansion unit)
This section describes how to mount the DIN rail mounting type: GT-
72A/72AP (Expansion unit).
The expansion unit can only be used in addition to the main unit.
Up to nine expansion units can be added to one main unit.
• When adding an expansion unit(s), be sure to use a
24 VDC power supply.
• An expansion unit of different output type cannot be
added (for example, an expansion unit of NPN output
cannot be added to a main unit of PNP output).
• An expansion unit of the DIN rail mounting type cannot
be added to a main unit of the panel mounting type.
1
Detach the expansion cover of the main unit.
2
Mount the expansion unit to be added to the DIN rail.
Refer to page 2, "DIN rail mounting type (Main unit)", for details
about how to mount.
3
Push and fix the expansion unit to the connector of the main
unit until it clicks.
4
Mount the end units (OP-26751: a set of two pieces) on both
sides of the amplifiers (the main unit and the expansion unit),
then fix the end units with screws on the upper part of each
end unit (2 points x 2 units).
The mounting method of the end unit is the same as that of the
amplifier.
● Panel mounting type (Main unit)
This section describes how to mount the panel mounting type: GT-
75A/GT-75AP (Main unit).
1
Create a panel opening for mounting referring to the
dimensions below.
2
Insert the main unit, back end first, into the opening of the
panel.

CAUTION
• When adding an amplifier (expansion unit), be
sure the power of both main and expansion
units is OFF before operation. Mounting when
the power is ON may damage the equipment.
• Be sure to completely contact an expansion unit
to a main unit. Oblique or improper connections
may damage the equipment.
