The COMBIVERT R6 must be protected against invalid loading. Components
and covers must not be bent or moved as this may affect insulation distances.
The units contain electrostatic sensitive devices which can be destroyed by
inappropriate handling. For that reason the contact of electronic devices and
contacts is to be avoided. The equipment must not be switched on if it is dam-
aged as it may no longer comply with mandatory standards.
Make sure that during installation there is enough minimum clearance and
enough cooling. Climatic conditions must be observed in accordance with the
instruction manual.
Heat sinks can reach temperatures, which can cause burns when touching. If
in case of structural measures a direct contact cannot be avoided, a warning
notice "hot surface" must be mounted at the machine.
Before any installation and connection work, the system must be switched off
and secured.
After clearing the DC link capacitors are still charged with high voltage for
a short period of time. The unit can be worked on again, after it has been
switched off for 5 minutes.
The terminals of the control terminal strip are securely isolated in accordance
with EN 61800-5-1. With existing or newly wired circuits the person installing
the units or machines must ensure that the EN requirements are met. With
frequency inverters that are not isolated from the supply circuit all control
lines must be included in other protective measures (e.g. double insulation or
shielded, earthed and insulated).
The connection of COMBIVERT R6 is allowed to:
symmetrical mains with a voltage phase (L1, L2, L3) with respect to neutral
conductor/ ground (N/PE) of maximum 305 V.
The COMBIVERT R6 is designed for fixed connection, since discharge cur-
rents of > 3.5 mA occur especially when using together with EMC filters. There-
fore, the requirements or instructions from EN 60204-1 (VDE 0113) and EN
61800-5-1 (IEC 0160-5-1) must be observed.
