4.5 On-Site Inverter Installation
After both switch cabinet units have been installed next to each other, the transport locks of the
sinusoidal filter have to be removed, the seals have to be inserted and the individual cabinets have to
be mechanically and electrically connected for the final mounting in the operating room. All necessary
materials required for connecting the switch cabinets are included in the delivery.
4.5.1 Mechanical Coupling
The mechanical connection of the two cabinets is done using baying clamps. They consist of terminal
clamps and brackets with which the cabinets can be screwed together in several places. In order to
do this, both cabinets have to be at the same level.
NOTICE!
Moisture ingress due to lack of sealing!
• Before the two cabinets can be mechanically joined together, the seals provided must
be glued into the appropriate recesses in the cabinets, if this has not already been
done by default.
NOTICE!
Damage due to impurities!
• Do not carry out any machining work on or in the inverter.
• Remove impurities from the Sunny Central.
• Seal openings.
Observe the installation guide of the switch cabinet manufacturer.
The installation of the seals and baying clamps is described in the installation guide from
the Rittal company annexed to this document.
