Rated current for light load
Application for LIFTS - INTERMITTENT duty (*)
Maximum starting current
Ambient temperature 0 ÷ 50°C . Degree of protection IP20
(*) Duty is considered intermittent where the motor drive starts for a duration below or equal to 60" each 120".
*Consider the real currents of the system, sometimes the real currents are higher than the ones on the data plate.
If the motor data is available, consider the imax (starting current with full load on ascent with cold oil).
In order to protect the power component (SCR) and to avoid dangerous conditions
in the event of a short circuit, you are advised to install, upstream of the power line
(L1-L2-L3), 3 fuses with an I²t the the one is supported by the SCR.
The fuses shown in the Table ensure Type 2 protection.

isolations and maximum temperatures allowed by the cables.
The Table shows the minimum cross sections, where FS17 type cables are used.
Power terminals L1-L2-L3-U-V-W
Command terminals 1-2-3-4-5
SMS-Hstart can be connected either on the line that powers the motor (Fig. 1), or inside the delta
of the motor (Fig. 2), if you are using a motor with the windings connected in delta when powered
by mains voltage (i.e. 400/690 motor with 400V mains power or 230/400 motor with 230V mains
power).
When SMS-Hstart is connected to the delta, the current passing through it (IF) is 1.6 times lower
than the line current (IL). It can therefore be used for motors with a rated current 1.6 times greater
rated current.
