INSTALLATION
OJ-AIR2-HMI-35T can be installed in two ways: either in a wall box/
panel front or directly on a flat surface.
Installation on flat surface
The back cover of the HMI is equipped with a keyhole-shaped opening which can be used to hang
the unit on a flat surface (see Fig. 1). Use a screw that is max. 3.5 mm in diameter with a head no
larger than 9 mm.
Installation in wall box/panel front
If OJ-AIR2-HMI-35T is to be installed in a wall box or panel front, the back cover must be removed.
Firstly, the front cover must be detached by gently releasing the catch on the bottom of the unit
with a flat screwdriver and then tipping the cover outwards (see Fig. 2).
Once the front cover has been detached, the two screws holding the back cover in place can be
removed (see fig. 3). The back cover can now be detached and the front cover refitted. The baseplate
is equipped with several screw holes. The dimensioned drawing (see fig. 4) can be used as a drilling
template. The baseplate should be secured with at least two screws tightened to a torque of max.
0.8 Nm. Installation depth is 20 mm.
MODBUS CONNECTION
OJ-AIR2-HMI-35T is connected to the OJ-Air2 Master by means of a Modbus cable. The Modbus ca -
ble can be connected to the OJAIR2- HMI-35T by means of the RJ12 6P4C port or four single-wire
screw terminals. Whether the RJ12 6P4C port or screw terminals are used does not influence the
available functions or operation.
Modbus RJ12 6P4C
Connect the Modbus cable to the Modbus port for a hand terminal on the OJ-Air2 Master and to
the RJ12 6P4C port on the OJ-AIR2- HMI-35T (see fig. 5).
Modbus screw terminals
Connect the Modbus cable to the Modbus port for a hand terminal on the OJ-Air2 Master and to
the corresponding screw terminals on the OJ-AIR2-HMI-35T (see fig. 6).
