Transport, storage and installation
The storage of the COMBIVERT must be done in the original packing. It is to be protected against humidity
and excessive cooling and thermal effect. A long-distance transport must be carried out in the original packing.

packing the COMBIVERT must be set down on a stable base.
Protect
Against
Accidental
Contact
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 electro-
static sensitive devices which can be destroyed by inappropriate handling. For that reason
the contact of electronic components and contacts is to be avoided. The equipment must
not be switched on if it is damaged 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.
Hot Surface
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.
Electrical connection
Note Capacitor
Discharge Time
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.
Secure
Isolation
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 iso-
lated from the supply circuit all control lines must be included in other protective measures
(e.g. double insulation or shielded, earthed and insulated).
Voltage With Re-
spect To Ground
Connection of the COMBIVERT R6 is only permissible on symmetrical networks with a
maximum line voltage (L1, L2, L3) with respect to ground (N/PE) of 317V. An isolating
transformer must be used for supply networks which exceed this value! The units may be
damaged if this is not observed.
Earthed Ex-
ternal
Conductor
The COMBIVERT R6 can be connected to power systems with earthed external conductors
(e.g.deltapowersystems)ifthefollowingexceptionsapply:
the control system is no longer regarded as “securely isolated circuit”, further protection •
measures are required therefore
with this type of power system, the max. • voltage phase / earth must not exceed 550 V
absolute
external DC fuses at the DC connections are necessary for the 400 V class. Use the •
COMBIVERT R6-S without internal DC fuses.
