Important
The power cables must be twisted for EMC reasons.
Attention
No reverse polarity protection! Always ensure that the power cables are connected correctly,
otherwise the Drive may be damaged beyond repair!
Note
SOMANET servo drives are densely packed with high-performance components. Even at idle/torque
off, several components such as power supplies, cause the servo drive to get warm, especially when
it’s not connected to any heat conducting structure. The servo drives’ power stages and control
algorithms were optimized for efficiency at high power output and actually make them one of the
most efficient servo drives available. The heat generation is not linear, which makes it actually more
noticable at idle or low power. Please ensure by design of your mounting situation that the heat
interface is connected to sufficient structure to appropriately dissipate generated heat.
Note
Use a protected extra-low voltage (PELV) power supply.
1.1.1.1.1 Warning about using contactors behind the power supply
Attention
Our servo drives are designed for voltages between 24 V and 48 V (55 V ; Max,cont 60 V
Max,peak), 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.
1.1.1.1.1.1 Functional Earth
Functional Earth (FE) and the Ground (GND) of the electronic boards are electrically isolated.
The blank bottom side of the heatsink has a flat conductive surface and can be used as a connection for
Functional Earth (FE).
For a better EMI shielding around the electronic boards, it is necessary to electrically connect the
conductive surfaces (marked blue in the following picture) to the chassis of the motor or the robot.
Important
Please ensure that the chassis is properly grounded.
