Installing the MC-1200

DIN-rail Mounting

The MC-1200 comes with a DIN-rail mounting kit. To install the DIN-rail mounting kit, do the following:

STEP 1: Use the 4 screws included with the kit to attach the DIN-rail mounting bracket to the MC-1200’s rear panel and tighten the screws to secure the bracket to the MC-1200.
STEP 2:
Insert the top of the DIN rail into the slot just below the upper hook of the DIN-rail mounting kit.
STEP 3: Press the MC-1200 towards the DIN rail until it snaps into place.
Removal:
STEP 1:
Pull down the latch on the mounting kit with a screwdriver.
STEP 2 & 3: Slightly pull the MC-1200 forward and lift it up to remove it from the DIN rail.

For the specifications of the DIN-rail mounting screws, refer to the illustration on the right and adhere to these values to secure the DIN-rail bracket to the rear panel of the computer.

Wall Mounting

The MC-1200 can be installed on a wall by using the optional wall-mounting kit. The wall-mounting kit must be purchased separately.

STEP 1:
Use three screws for each bracket and attach the brackets to the rear of the MC-1200.

Refer to the figure on the right for the specifications of the screws used to attach the mounting brackets.
STEP 2:
Use two screws per bracket to attach the MC-1200 to a wall or cabinet.

Note:
Mounting the MC-1200 to a wall requires four screws. Use the MC-1200 computer, with the optional 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 less than 6.0 mm in diameter, and the shafts should be less than 3.5 mm in diameter as shown in the figure on the right. Do not drive the screws in all the way; leave a space of about 2 mm to allow room for sliding the wall-mounting bracket between the wall and the screws.

Connector Description

Power Connector

Use an LPS (9-36 VDC) or Class 2 power cord to connect to the MC-1200’s terminal block to power jack converter and then turn on the power. If the power is supplied properly, the Power LED will light up. The OS is ready when the Power LED glows a solid green.

ATTENTION
This product is intended to be supplied by a Listed Power Supply with output marked LPS and rated to deliver 9 to 36 VDC at a minimum of 8 A.

Grounding the MC-1200
Grounding and wire routing help limit the effects of noise due to electromagnetic interference (EMI). Run the ground connection from the grounding screw (M4) to the grounding surface prior to connecting the power as shown in the illustration on the right.

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

Terminal Block
Terminal block (JP1)—R/C (XCFR2, XCFR8), socket soldered on to the PWB, DINKLE ENTERPRISE CO., LTD, type 2EHDRM, rated 300 V, 15 A, 105°C. Mating with plug type 2RSDAM, 2ESDPM, 2ESDPLM or 2ESDVM, rated 300 V, 15 A, 105°C. The plug-half connection is secured by screws; suitable for 12 to 24 AWG wire size, secured on plug by screws with a torque value of 0.5 N-m (4.4253 lb-in).

Ethernet Ports
