Wiring
After attaching the MBD-D to the panel, wire the device to the MBS-C. Use the MBD and
MBS-C connection cable (MBD-HS30) to connect POWER and ANALOG OUT in the I/O of the
MBS-C. In this case, wiring of the RELAY shown in the dotted lines is to be done by the
customer. The MBD-D receives the K(CA) signal from the MBS-C and display the first-stage
temperature. Connect the K thermocouple cable between K(CA) connector of MBS-C and K
thermo connector of MBD-D.
If you use other types of connection cables, refer to the MBS-C Instruction Manual Table 1-2 or
Appendix 2 “Attachments and Option Cables”.
<Notes>
1. Maximum length of our optional MBD and MBS-C connection cable (MBD-HS30) is 20 meters.
2. The dotted lines are to be wired by customers.

When routing cables;
In order to prevent mutual interference during operation, signal lines, control lines, and AC
power lines should be placed in separate conduits. Especially, do not route MBS analog
lines in a way such as to place together with AC power lines or control lines of other
equipments in a same conduit, or to bundle them together. It may cause interference to
MBS-C operation.
If separated conduits are not possible, keep enough distance between the lines (300mm
or more) to avoid the interference.
