Chapter 1 Safety Information and Precautions
1.1 Safety Definition
Danger: A Danger contains information which is critical for avoiding safety hazard.
Warning: A Warning contains information which is essential for avoiding a risk of damage to
products or other equipments.
Note: A Note contains information which helps to ensure correct operation of the product.
1.2 About Motor and Load
Compared to the industrial frequency operation
The MONT72 series controllers are voltage-type controllers and their output is PWM wave with certain
harmonic wave. Therefore, the temperature, noise and vibration of the motor will be a little higher than
that at industrial frequency running.
Thermal protection of motor
When choose the adaptive motor, MONT72 can effectively implement the motor thermal protection.
Otherwise it must adjust the motor protection parameters or other protection measures to ensure that
the motor is at a safe and reliable running.
Lubrication of mechanical devices
At long time low-speed running, provide periodical lubrication maintenance for the mechanical
devices such as gear box and geared motor etc. to make sure the drive results meet the site need.
Start and stop MONT72
User should use the control terminal to start and stop MONT72. It is strictly forbidden to use contactor
or other switches on the input side of MONT72 to start and stop directly, or it will damage the device.
Check the insulation of the motor
For the first time using the motor or after long time storage, it needs check the insulation of the motor.
Worse insulation can cause damage to MONT72.
Note:
Use a 500V Mega-Ohm-Meter to test and the insulation resistance must be higher than 5Mohm.
Requirement for leakage current protector RCD
Since the device generates high leakage current which goes through the protective grounding
conductor, please install B type leakage current protector RCD on one side of the power supply.
For the selection of RCD, users need to consider the possible problems of ground leakage current in
both transient status and steady status at start and during running. It is recommended to choose
either special RCD that can suppress the higher harmonics, or general RCD that has more aftercurrent.
