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 :MR-J2S-10A to MR-J2S-22KA
MR-J2S-10A1 to MR-J2S-40A1
Servo motor :HC-KFS
HC-MFS
HC-SFS
HC-RFS
HC-UFS
HA-LFS
HC-LFS
(2) Installation
Install a cooling fan of 100CFM (2.8m3/min) air flow 4 in (10.16 cm) 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-circu it tests of the UL in the alternating-cu rrent 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 no t touch the charging section for
15 minutes after power-off.
Servo amplifier Discharge time

MR-J2S-10A(1) 20A(1) 1
MR-J2S-40A(1) 60A 2
MR-J2S-70A to 350A 3
MR-J2S-500A 700A 5
MR-J2S-11KA 4
MR-J2S-15KA 6
MR-J2S-22KA 8
(5) Options and auxiliary equipment
Use UL/C-UL standard-compliant products.
(6) Attachment of a servo motor
For the flange size of the machine side where the servo motor is installed, refer to “CONFORMANCE
WITH UL/C-UL STANDARD” in the Servo Motor In struction Manual.
