DANGER!
The AC input voltage must be compatible with the Soft-Starter SSW-06
rated voltage.
DANGER!
Provide power supply disconnecting switch. This disconnecting switch
must disconnect the AC input voltage from the Soft-Starter SSW-06,
always when required (for instance during maintenance services).
DANGER!
If a disconnect switch or a contactor is inserted in the motor supply
line, DO NOT operate these devices with running motor or when
Soft-Starter SSW-06 is enabled.
ATTENTION!
Control of overvoltage in the line that supplies the Soft-Starter must be
made using surge protection with a voltage of 680 Vac (phase to phase
connection) and energy absorption capacity of 40 joules (for models
from 85A to 205A) or 80 joules (for models from 255A to 1400A).
NOTE!
Use wire sizing and fuses as recommended in Table 3.6, 3.7 and 3.9.
The connector tightening torque is as indicated in Table 3.5. Use 70ºC
(158ºF) copper wires only.
