Terminate Earthing electrodes
Important
•
For EMC compliance, it is important that a local Earthing electrode is used to bond the chassis of the IPU
directly to ground. This may be in the form of an earth stake, or if available, can be bonded to pre-existing
buried earth structures.
•
Prior to installation of the unit, a professional review of local lightning protection requirements must be
performed to ensure that laws and regulations are adhered to. As a result, it may be necessary to install
additional earthing electrodes for outdoor installations.
Terminate the bandeizen/earth electrodes to the IPU earth busbar as shown in section
Terminate the integrated power unit DC link
. If metal foundation plates are used, terminate to
each IPU chassis or earth busbar.
