Altitude Output current must be reduced 1 % for every 100 m over
1000 m. For altitudes over 3000 m, manufacturer must be
consulted.
Pollution degree Pollution degree 2 according to NEMA ICS-1, IEC664 and
UL840

Shock IEC68-2-27
1.3 Normal operation
The inverter goes into the ready-to-run state within one second after the power supply is connected. During running
the inverter follows the operator’s speed reference according to the set acceleration/deceleration ramp. During
direction change the brake is kept open all the time. When drive command is switched off the inverter decelerates
to zero according to the set ramp and closes the mechanical brake.
1.4 Status indication leds (green and red)
The inverter indicates its operating state by two leds. Red led indicates “fault state” (driving is inhibited). Green led
indicates “ok-state”. Blinking of green led indicates that fault state has been active, but it has been recovered.
Normal driving is however possible also when green led is blinking (in other words, blinking of green led does not
indicate “warning-state”).

The programming of the inverter is performed by dip-switches. The state of each switch is either OFF (0) or ON (1).
It is possible to set he following parameters by the switches S1-S6.
S1 = Maximum speed
S2 = Minimimum speed
S3 = Acceleration / deceleration time
