2.5 Start-up and during operation
Caution!
•
During commissioning, unexpected and hazardous conditions can arise in the entire installation due
to defective adjustments, defective components or incorrect electrical connections. Remove all
persons and objects from the hazardous area.
•
During operation, the device must be closed or installed in a control cabinet. Fuses may only be
replaced by new ones and must not be repaired or bypassed. The data for the maximum line fuse
are to be considered absolutely (see Technical data). Use only fuses specified in schematic
diagrams.
•
Any faults detected in the electric system/modules/operating equipment must be corrected
immediately. If these faults are not corrected, the device/system is potentially very dangerous. The
device/system must therefore not be operated when it is faulty.
•
Pay attention to smooth, low vibration running of the motor/fan, the appropriate instructions in the
drive documentation must be observed!
2.6 Working on device / Hazards through “residual voltage”
Information
Mounting, electrical connection, and start-up operation may only be carried out by an electrical
specialist in accordance with electrotechnical regulations (e.g. EN 50110, EN 60204, NFPA79)!
USA siehe NEC (National Electrical Code), CANADA siehe CEC (Canadian Electrical Code).
Danger due to electric current
•
It is generally forbidden to carry out work on electrical live parts. Protection class of the device when
open is IP00! It is possible to touch hazardous voltages directly.
•
The safe isolation from the supply must be checked using a two-pole voltage detector.
•
Even after disconnecting the mains voltage, life-threatening charges can appear between the
protective ground “PE” and the mains connection.
•
The protective earth is conducting high discharge currents (dependent on the switching frequency,
current-source voltage and motor capacity). Earthing in compliance with EN specifications shall
therefore be observed even for testing and trial conditions (EN 50 178, Art. 5.2.11). Without
earthing, dangerous voltages can be present on the motor housing.
•
Never remove the device from the motor when connected to line voltage!
Waiting period at least 5 minutes!
•
Through use of capacitors, danger of death exists even after switching off the device through
directly touching the energized parts or due to parts that have become energized due to faults.
•
It is only permitted to remove the housing cover after waiting for 5 minutes once the line supply
cable has been shut down. Should measurement or adjustment work be unavoidable on the
opened unit while still powered, then this may only be performed by qualified personnel acquainted
with the thereby associated hazards.
Caution!
Automatically restart after a power failure or mains disconnection!
2.7 Modifications / interventions in the device
Caution!
For reasons of safety, no unauthorized interventions or modifications may be made on the device. All
planned modifications must be authorized by the manufacturer in writing.
Use only genuine spare parts / genuine wearing parts / genuine accessories from ZIEHL-ABEGG.Th-
ese parts were specifically designed for the device. There is no guarantee that parts from non-original
sources are designed and manufactured in correspondence with load and safety requirements.
Parts and optional equipment not supplied by ZIEHL-ABEGG are not approved by ZIEHL-ABEGG for
use.
