1.5.2.2.1.1.1.1 Warning about using contactors behind the power supply
Attention
Our servo drives are designed for voltages between 24 V and 48 V (60 V Max), they should be run with
an appropriate extra-low voltage supply. Please do not use contactors behind the power supply
since the transient-voltage-suppression diodes could get damaged due to the power-up voltage
increase (Surge). This is likely to happen when the power up occurs fast and can lead to complete
failure of your servo drive.
If contactors behind the power supply are used, it’s necessary to include an uni-directional TVS diode
type 1.5KE62A-E3/54* between Main Power Supply and Ground of the terminal.
* this model has been successfully tested by Synapticon. Other products with the same specifications
may also be appropriate but can’t be recommended.
In case you are running several servo drives behind a contactor, please use an uni-directional TVS diode on
each drive because of the inductances of the wiring.
