Notes: 1.
2.
When using the MR-RB50, always forcibly cool with
the cooling fan (approx. 1.0m
3
/min, M92).
Create a sequence that turns off the magnetic
contactor (MC) when abnormal overheating occurs.

● Junction terminal block (MR-TB50)
All signals can be recieved with this junction terminal block without a connection to CN1.
Notes: 1. The optional regeneration unit will heat up to approx. 100°C (212°F), so do not directly mount it on a wall susceptible to heat. Use nonflammable wires or provide flame resistant
treatment (use silicon tubes, etc.), and wire so that the wires do not contact the optional regeneration unit.
2. Always use twisted wires for the optional regeneration unit, and keep the length as short as possible (5m (16.4 ft) or less).
3. Always use twisted wires for a temperature detector, and make sure that the detector does not fail to work properly due to inducted noise.
