The figures in winding capacity and minimum fall load are obtained with the use of 8B drum.

"a/b" in speed and full-load current are measured under the 50Hz ; "a" and 60Hz ; "b" power respectively.

Use environment : Ambient temperature ; -10℃ to +40℃ (subject to no freezing ・ dew condensation). Ambient humidity less than 85%RH

Time rating is the value measured at +20℃. If the temperature exceeds this value, the time rating gets shorter.

Shutter shall be surely equipped with the emergency limit switch.

Durability : 10,000 opening and closing

It is available to produce the operator with different operating voltage except.
