2.3 Residual hazards
Pr
oduct
Observe the warning labels on the product!
Icon Descripon
Electrostac
sensive devices:
Before working on the product, the sta must ensure to be free of electrostac charge!
Dangerous electrical voltage
Be
fore working on the product, check if no voltage is applied to the power terminals!
Aer mains disconnecon, the power terminals carry the hazardous electrical voltage for the me given next to the symbol!
High leakage current:
Carr
y out xed installaon and PE connecon in compliance with EN 61800−5−1 or EN 60204−1!
Hot surface:
Use per
sonal protecve equipment or wait unl the device has cooled down!
Motor
protecon
With some sengs of the inverter, the connected motor can be overheated.
•
E. g. by longer operaon of self-venlated motors at low speed.
•
E. g. by longer operaon of the DC-injecon brake.
Protecon of the machine/system
Drives can reach dangerous overspeeds.
•
E. g. by seng high output frequencies in connecon with motors and machines not suita-
ble for this purpose.
•
The inverters do not provide protecon against such operang condions. For this pur-
pose, use addional components.
Switch contactors in the motor cable only if the controller is inhibited.
•
Switching while the inverter is enabled is only permissible if no monitoring funcons are
acvated.
Motor
If there is a short circuit of two power transistors, a residual movement of up to 180°/number
of pole pairs can occur at the motor! (e. g. 4-pole motor: residual movement max. 180°/2 =
90°).
Degree of protecon - protecon of persons and device protecon
•
Informaon applies to the mounted and ready-for-use state.
•
Informaon does not apply to the wire range of the terminals.
-
Terminals that are not assigned only have a low protecon against contact.
-
Terminals for large cable cross-secons have lower classes of protecon, e. g. from
15 kW IP10 only.
