When using the MR-RB5H-4, always forcibly cool with a
cooling fan (approx. 1.0m
3
/min, M92). The cooling fan
must be ordered by user.
Create a sequence that turns off the magnetic contactor
(MC) when abnormal overheating occurs.

2.
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.
Always use twisted wires for the optional regeneration unit, and keep the length as short as possible (5m (16.4ft) or less).
