(3) USA/Canada compliance
This servo amplifier is designed in compliance with UL 508C and CSA C22.2 No. 14.
(a) Installation
The minimum cabinet size is 150% of each MR-J4 servo amplifier's volume. Also, design the cabinet
so that the ambient temperature in the cabinet is 55 °C or less. The servo amplifier must be installed
in the metal cabinet. Additionally, mount the servo amplifier on a cabinet that the protective earth
based on the standard of IEC/EN 60204-1 is correctly connected. For environment, the units should
be used in open type (UL 50) and overvoltage category shown in table in section app. 4.8.1. The
servo amplifier needs to be installed at or below pollution degree 2. For connection, use copper
wires.
(b) Short-circuit current rating (SCCR)
Suitable For Use On A Circuit Capable Of Delivering Not More Than 100 kA rms Symmetrical
Amperes, 500 Volts Maximum (Not More Than 5 kA rms Symmetrical Amperes, 48 Volts Maximum
for MR-J4-03A6 and MR-J4W2-0303B6). For SCCR when using a Type E Combination motor
controller, refer to section 11.6.
(c) Overload protection characteristics
The MR-J4 servo amplifiers have solid-state servo motor overload protection. (It is set on the basis
(full load current) of 120% rated current of the servo amplifier.)
(d) Over-temperature protection for motor
Motor Over temperature sensing is not provided by the drive.
Integral thermal protection(s) is necessary for motor and refer to app. 4.4 for the proper connection.
(e) Branch circuit 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 with the
Canada Electrical Code and any applicable provincial codes.
(4) South Korea compliance
This product complies with the Radio Wave Law (KC mark). Please note the following to use the
product.
