DYNAVERT L
SAFETY INSTRUCTIONS
5
Version: 11.10.02
4Bs0503en/002
Please help preclude any faults and thus avoid injury of persons and property damage.
The person responsible for the system must guarantee that
−
safety notes and operating instructions are available and observed;
−
operating conditions and technical data are observed in accordance with the order;
−
protective devices are used;
−
prescribed maintenance is performed;
−
service staff is immediately called or the system is immediately shut down, if there are higher
−
temperatures, noise, vibrations, etc. as compared to nominal operation;
The operating instructions contain all the information an expert needs for using the electrical system in industrial
plants. Additional information and hints for unqualified persons, for application of the system in a non-industrial field,
and for possible drive variants are not contained in this manual.
The manufacturer's guarantee is only valid, if the respective applicable operating instructions have been observed
and adhered to.
Device specific General remarks referring security
−
The output side of DYNAVERT L inverters is stable at no load, short-circuit-proof, and earth-fault -proof.
−
The earthing cable of the electronic section is electrically connected to PE.
−
All the operation and signal inputs (terminal strip) are isolated from the electronic section earth by means of opto-
couplers. Therefore best prerequisites are set to guarantee electromagnetic compatibility.
−
All the conductive connections are still energized after the mains voltage has been switched off, until the link
capacitor has discharged (approx. 5 min.).
−
Before starting to work check the residual voltage after the discharging time period.
−
Connections at the terminal strip may only be performed, if the inverter is de-energized.
−
Withdraw plug connections and electronic boards only, if the inverter is de-energized.
−
In order to protect the power transistors of the input rectifier off explosion (in case of breakdown of all protection
systems) there are semiconductor fuses installed at the mains side.
−
As a matter of principle only PCB-free and beryllium-oxide-free components are used. When the DYNAVERT L is
put out of service it must be appropriately disposed of.
