CONFORMANCE WITH UL/C-UL STANDARD

(1) Servo amplifiers and servo motors used

Use the servo amplifiers and servo motors which comply with the standard model.

Servo amplifier :MR-J3-10B to MR-J3-22KB

MR-J3-10B1 to MR-J3-40B1

MR-J3-11KB4 to MR-J3-22KB4

Servo motor :HF-MP

HF-KP

HF-SP

HC-RP

HC-UP

HC-LP

HA-LP

(2) Installation

Install a fan of 100CFM (2.8m

/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-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.
