CONFORMANCE WITH UL/C-UL STANDARD
(1) Servo amplifiers and servo motor s used
Use the servo amplifiers and servo motors wh ich comply with the standard model.
Servo amplifier series :MR-J2S-10A(1) to MR-J2S-350A(1)
Servo motor series :HC-KFS
HC-MFS
HC-SFS
HC-RFS
HC-UFS
(2) Installation
Install a fan of 100CFM air flow 10.16 cm (4 in) above the servo amplifier or provide 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-circ uit tests of the UL in the alternating-curre nt circuit, the servo
amplifier conforms to the above circuit.
(4) Capacitor discharge time
The capacitor discharge time is as listed below . To ensu re safe ty, d o no t tou ch the ch arg ing sec tio n fo r
10 minutes after power-off.
