SMS -start SSV040 Manual De Uso página 9

Please read the manual before using and installing the device.
Read carefully the following paragraphs and pay attention to the instructions. Our warranty does
not cover any damage resulting from failure to follow instructions contained therein.
SMS-start is a three-phase asynchronous motor starter, designed to reduce starting current.
In hydraulic lift systems (1-second starting time), the starting current is reduced to less than
half of the direct starting current. In traditional rope lift systems (3-second acceleration time), a
starting current of approximately 0.7 times the direct starting current can be obtained.
SMS-start has two sizes with the same mechanical outfit but different electrical properties (see
pag. 10). Both include an internal Bypass function for the soft starter SCRs during runtime.
Please read this manual carefully before proceeding with installation or maintenance.
The safety warnings do not cover all causes of device failure, but do identify the most common causes.
The following symbols appear in this document or on the equipment to warn of potential hazards,
and they require special attention.
RISK OF ELECTRIC SHOCK
If the device is visibly damaged or missing components, or if the size of the device is not suitable
for the motor, DO NOT proceed with installation.
When the device is connected to the mains it is subject to hazardous voltages.Installation,
inspection and maintenance of the device must be performed by authorised and appropriately
trained personnel, and should be performed only when it is disconnected from the electric network.
Incorrect installation can cause equipment malfunction, injury or even death. Carefully follow the
safety regulations in force..
The device must be connected to GROUND and the circuits adequately protected, in accordance
with current standards.
To ensure correct device operation and in order to avoid the risk of fire, use cables with a suitable
cross section, depending on the current and the length of the connection.
Ensure that no type of external object enters the device, as it can lead to failure of the product or
hazardous conditions, when connecting to the electric network. Make sure that there is no voltage
on the device control terminals which could link to the electric network.The control and power
conductors must be correctly isolated from each other.
Any static power factor correction unit must be connected upstream of the device (Terminals L1-
L2-L3) and never downstream (Terminals U, V, W). Incorrect connection may cause hazardous
conditions and/or device breakage.
The examples and diagrams in this manual are included solely for demonstration purposes.
The content of this manual is subject to change without notice.
In no event shall liability be accepted for damage, indirect or consequential, resulting from the use
or application of the device.
