          *1 Risk time according to IEC60947-5-3 is 150 ms + 2 ms × (number of units cascaded -1).
          *2 If the OSSD operation is open/close link mode, Detect→ Not detect: 20 ms + 2 ms × (number of units cascaded -1), Not detect → Detect: 30 ms + 25 ms × (number of units cascaded -1)
          *3 430 ms when locked at the same time the actuator is detected.
          *4 Acceptable door operation frequency is 3 Hz if the OSSD operation is open/close link mode. In that case, operation distance is Sao(OFF→ ON) = 3 mm, Sar(OFF→ ON) = 10.5 mm.
          *5 Do not apply excessive torque (0.45 N·m or higher).
          *6 The number of AUX outputs is 1 when the OSSD operation is open/close link mode.
          *7 The number of OSSD operation switching inputs is 1 when the OSSD operation is lock link mode.
          *8 Power consumption temporarily increases (Max. 10.5 W, Approx. 0.2 s) when the lock control input(s) is(are) turned ON. After that, current consumption will be within the specification.
