App. 4.3 Installation direction and clearances
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.
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.
