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 (16.4ft) or less).

Notes: 1. The tolerable regenerative power in the table differs from the regenerative resistor’s rated wattage.
2. For the values given in parentheses, install cooling fans (approx. 1.0m
3
/min, M92✕2 units), and change the parameter No. 0 (for MR-J2S-A type) or No. 2 (for MR-J2S-B type).
