Lenze i750 User Manual

Residual hazards
Even if notes given are taken into c
onsideraon and protecve measures are implemented,
the occurrence of residual risks cannot be fully prevented.
The user must take the residual hazards menoned into consideraon in the risk assessment
for his/her machine/system.
If the above is disregarded, this can lead to severe injuries to persons and damage to
property!
Product
Observe the warning labels on the product!
Dangerous electrical voltage:
Be
fore working on the product, make sure there is no voltage applied to the power terminals!
Aer mains disconnecon, the power terminals will sll carry the hazardous electrical voltage
for the me given next to the symbol!
Electrostac sensiv
e devices:
Before working on the product, the sta must ensure to be free of electrostac charge!
High leakage current:
Carr
y out xed installaon and PE connecon in compliance with:
EN 61800‑5‑1 / EN 60204‑1
Hot surface:
Use per
sonal protecve equipment or wait unl the device has cooled down!
Degree of pr
otecon - protecon of persons and device protecon
•
In
formaon applies to the mounted and ready-for-use state.
•
Informaon does not apply to the wire range of the terminals.
-
Terminals that are not wired have low protecon against physical contact.
-
Terminals for large cable cross-secons have lower classes of protecon, e. g. from
15 kW IP10 only.
Protecon of per
sons
Before working on the inverter, check if no voltage is applied to the power terminals.
•
Depending on the device, the power terminals X105 remain live for up to 20 minutes.
•
The power terminals X100 and X105 remain live even when the motor is stopped.
Device protecon
•
The ma
ximum test voltage for insulaon tests between a control potenal of 24 V and PE
must not exceed 110 V DC (EN 61800‑5‑1).
Motor pr
otecon
With some sengs of the inverter, the connected motor can be overheated.
•
E. g. by longer operaon of self-venlated motors at low speed.
•
E. g. by longer operaon of DC-injecon braking.
Protecon of the machine/system
Drives can reach dangerous overspeeds.
•
E. g. by seng high output frequencies in connecon with motors and machines not
suitable for this purpose.
•
The inverters do not provide protecon against such operang condions. For this
purpose, use addional 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 funcons are
acvated.
