Dimensions-4-Installing the MC-3201
Wall Mounting
The MC-3201 can be installed on a wall by using the wall-mounting kit.
To install the MC-3201 on a wall, do the following:
STEP 1:
Use four screws for each bracket and attach the brackets to theback of the MC-3201.

The screws are included in the wall-mounting kit. If you want tobuy the screws separately, use the following specifications:
Screw-M/FMS M4 x 6mm Ni/90D Nylok
STEP 2:
Use two screws per bracket to attach the MC-3201 to a wall orcabinet.

Note:
Mounting the MC-3201 to a wall requires
four screws. Use the MC-3201 computer,with the wall-mounting brackets
attached, as a guide to mark the correct
locations of the screws on the wall.
The heads of the screws should be atleast 6.0 mm in diameter, the shafts
should be 3.5 mm in diameter with aminimum depth of 10 mm as shown in
the figure on the right. Do not drive thescrews in all the way; leave a space ofabout 2 mm to allow room for sliding thewall-mounting bracket between the walland the screws.

Power Connector
Connect the power connector/terminal block to thepower supply that can provide 9 to 36 VDC (MC3201-TGL1 model) or 24 VDC (MC-3201-TGL7model). Before connecting the device to DC power
inputs, make sure the DC power source voltage isstable. If the power is supplied properly, the PowerLED will light up. The OS is ready when the PowerLED glows solid green.
The input terminal block wiring should be installed
by a skilled person.
• Wire size: 12-28 AWG• Torque value: 0.51 N-m• Only one conductor per clamping point
If you are using a Class I adapter, the power cordshould be connected to an outlet with an earthing
connection.

ATTENTION
The equipment (MC-3201-TGL7-M-S) is intended to be suppliedby the external power source (UL listed/ IEC 60950-1/ IEC62368-1), which output complies with ES1/SELV, output ratingis 24 VDC, 2.7 A min., an ambient temperature 55°C
minimum.

ATTENTION
The equipment (MC-3201-TGL1-S-S) is intended to be suppliedby the external power source (UL listed/ IEC 60950-1/ IEC62368-1), which output complies with ES1/SELV, output rating
is 9 to 36 VDC, 9.5 A min., an ambient temperature 55°C
minimum.
Grounding the MC-3201
Grounding and wire routing help
limit the effects of noise due toelectromagnetic interference (EMI).
Run the ground connection fromthe functional earthing screw (M4)
to the grounding surface prior toconnecting the power as shown in
the illustration on the right.

-6-NOTE

A 4 mm2 conductor must be used when the connection to theexternal grounding screw is utilized. The heat sink is grounded
to the chassis by an internal screw.

Terminal Block
Terminal block (J1)—R/C (XCFR2, XCFR8), socket soldered on to thePWB, DINKLE ENTERPRISE CO., LTD, type 5EHDRM, rated 300 V, 15 A,105°C. The terminal block is suitable for connecting to plug type
5ESDVM rated 300 V, 15 A, 105°C. The plug-half connection is secured
by screws; suitable for 12 to 28 AWG wire size, secured on plug byscrews with a torque value of 0.51 N-m (4.5 lb-in).
