Safety Precautions
SYSDRIVE MX2 Series USER'S MANUAL (3G3MX2-Axxxx)
Do not connect resistors to the terminals (+1, P/+2, N/−) directly.
Doing so might result in a small-scale fire, heat generation or damage to the unit.
Install a stop motion device to ensure safety. Not doing so might result in a minor injury. (A holding 
brake is not a stop motion device designed to ensure safety.)
Be sure to use a specified type of braking resistor/regenerative braking unit. In case of a braking 
resistor, install a thermal relay that monitors the temperature of the resistor. Not doing so might result 
in a moderate burn due to the heat generated in the braking resistor/regenerative braking unit. 
Configure a sequence that enables the Inverter power to turn off when unusual overheating is 
detected in the braking resistor/regenerative braking unit.
The Inverter has high voltage parts inside which, if short-circuited, might cause damage to itself or 
other property. Place covers on the openings or take other precautions to make sure that no metal 
objects such as cutting bits or lead wire scraps go inside when installing and wiring.
Take safety precautions such as setting up a molded-case circuit breaker (MCCB) that matches the 
Inverter capacity on the power supply side. Not doing so might result in damage to property due to 
the short circuit of the load.
Do not dismantle, repair or modify this product.
Doing so may result in an injury.
