(2) Installation
Install a fan of 100CFM (2.8m
cooling of at least equivalent capability.
(3) Short circuit rating
This servo amplifier conforms to the circuit whose peak current is limited to 5000A or less. Having
been subjected to the short-circuit tests of the UL in the alternating-current circuit, the servo
amplifier conforms to the above circuit.
(4) Capacitor discharge time
The capacitor discharge time is as listed below. To ensure safety, do not touch the charging section for
15 minutes after power-off.
