CONFORMANCE WITH UL/C-UL STANDARD
(1) Servo amplifiers and servo motor s used
Use the servo amplifiers and servo motors which comply with the standard model.
Servo amplifier series :MR-J2S-10CP to MR-J2S-700CP
MR-J2S-10CP1 to MR-J2S-40CP1
Servo motor series :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 cap ability.
(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-current c ircuit, the servo
amplifier conforms to the above circuit.
(4) Capacitor discharge time
The capacitor discharge time is as lis ted below. To ensure safety, do not touch the charging se ction for
15 minutes after power-off.
Servo amplifier Discharge time [min]
MR-J2S-10CP(1) 20CP(1) 1
MR-J2S-40CP(1) 60CP 2
MR-J2S-70CP to 350CP 3
MR-J2S-500CP 700CP 5
(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 Instr uction Manual.
(7) About wiring protection
For installation in United States, branch circuit protection must be provided, in accordance with the
National Electrical Code and any applicable local codes.
For installation in Canada, branch circuit protection must be provided, in accordance wi th the Canada
Electrical Code and any applicable provinc ial codes.
