GENERAL
The MU5D is a plug-in type universal temperature converter that is connected to an IEC/JIS-standard thermocouple, converts the tem­perature signals into isolated DC current or DC voltage signals.

1. MOUNTING METHOD
NOTE
Plug/disconnect the main unit into/from the socket vertically to the socket face. Otherwise the terminals may bend and it may cause bad contact.
1.1 Wall Mounting
Unfasten the upper and lower stoppers of the converter to disconnect the main unit from the socket. Next, anchor the socket onto the wall with two M4 screws. Then, plug the main unit into the socket and se­cure the main unit with the upper and lower stoppers.

1.2 DIN Rail Mounting
Locate the converter so that the DIN rail fits into the upper part of the DIN-rail groove at the rear of the socket, and fasten the socket using the slide lock at the lower part of the socket.

1.3 Using Ducts
When using a wiring duct, install the duct at leaset 30 mm away from the top and bottom faces of the main unit.
Unit: mm
Note:
When mounting the units close together, leave a space of at least 5 mm between them.
(85)
Use the supplied spacer to keep a space of 5 mm for DIN rail mounting.

2. INSTALLATION LOCATIONS
Avoid the following environments for installation locations: Areas with vibration, corrosive gases, dust, water, oil, solvents, di­rect sunlight, radiation, a strong electric field, and/or a strong magnetic field Installation altitude: 2000 m or less above sea level.
If there is any risk of a surge being induced into the power line and/or signal lines due to lightning or other factors, a dedicated lightning arrester should be used as protection for both this con­verter and a field-installed device.
Operating temperature/humidity range: 0 to 50C/5 to 90%RH (no condensation)
3. EXTERNAL WIRING
WARNING
To avoid the risk of an electric shock, turn off the power supply and use a tester or similar device to ensure that no power is supplied to a cable to be connected, before carring out wiring work.
Wires are connected to the terminals of the converters socket. M3.5 screw terminals are provided for the connection of external signals. At­tach a crimp-on lug to each wire for connection to the terminals.
Recommended cables: A nominal cross-sectional area of 0.5 mm or thicker for signal cables, and that of 1.25 mm2 or thicker for power cables.

* Attach the RJC sensor correctly as shown in the figure above
only for thermocouple input.
IMPORTANT
The power line and input/output signal lines should be installed away from noise-generating sources. Other wise accuracy cannot be guaranteed.
The grounding resistance must be 100 Ω (JIS Class D grounding). The length and thickness of the grounding cable should be as short and thick as possible. Directly connect the lead from the ground terminal (terminal no.
9) of the product to the ground. Do not carry out daisy­chained inter-ground terminal wiring.
Use of the product ignoring the specifications may cause overheating or damage. Before turning on the power, en­sure the following:
(a)Power supply voltage and input signal value applied to the
product should meet the required specifications.
(b)The external wiring to the terminals and wiring to ground
are as specifications.
Do not operate the product in the presence of flammable or explosive gases or vapors. To do so is highly danger­ous.
The product is sensitive to static electricity; exercise care in operating it. Before you operate the product, touch a nearby metal part to discharge static electricity.
The RJC sensor may be damaged if an excessive force is applied. When attaching the RJC sensor, be sure not to pull it or not to bend the crimp-on terminal lugs.
