Installation direction and clearances
To adapt your machine using MR-J4-03A6 or MR-J4W2-0303B6 to IEC/EN 60950-1, either supply the amplifier with a power
supply complying with the requirement of 2.5 stated in IEC/EN 60950-1 (Limited Power Source), or cover the amplifier and
motors connected to the outputs with a fire enclosure.
*1 For 11 kW to 22 kW servo amplifiers, the clearance between the bottom and ground will be 120 mm or more.
*2 When mounting MR-J4-500_, maintain a minimum clearance of 25 mm on the left side.
Electrical Installation and configuration diagram
CAUTION
• The devices must be installed in the specified direction. Not doing so may cause a malfunction.
• Mount the servo amplifier on a cabinet which meets IP54 in the correct direction to maintain pollution degree 2.
• The regenerative resistor supplied with 11 kW to 22 kW servo amplifiers does not have a protective cover. Touching the resistor (including wiring/screw hole
area) may cause a burn injury and electric shock. Even if the power was shut-off, be careful until the bus voltage discharged and the temperature decreased
because of the following reasons.

It may cause a burn injury due to very high temperature without cooling.

It may cause an electric shock due to charged capacitor of the servo amplifier.
WARNING
• Turn off the molded-case circuit breaker (MCCB) to avoid electrical shocks or damages to the product before starting the installation or wiring.
CAUTION
• The installation complies with IEC/EN 60204-1. The voltage supply to machines must be 20 ms or more of tolerance against instantaneous power failure as
specified in IEC/EN 60204-1.
• Connecting a servo motor for different axis to U, V, W, or CN2_ of the servo amplifier may cause a malfunction.
• Securely connect the cables in the specified method and tighten them with the specified torque. Otherwise, the servo motor may operate unexpectedly.
