App. - 4
(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 MR-JE 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 app. 3.7.1. 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. For SCCR when using a Type E Combination motor controller, refer
to section 11.6.
(c) Overload protection characteristics
The MR-JE 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. 3.3 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
