5. EMC COMPLIANT ELECTRICAL CABINET WIRING RULES
P A N E L S A N D C A B I N E T S
Mounting panel and cabinet (including the doors) have to be grounded, with a direct connection to the ground
bus, using star washers if possible.
REMOVAL OF THE PAINT FROM THE SUPPORT AREAS
The paint should be removed from the choke, mounting panel and chassis, support areas.
The anodized aluminium does not conduct.
G R O U N D O F T H E
The inverters of AV-300 series are provided with two ground terminals: one must be connected to the ground
bus and the other to the filter.
G R O U N D T E R M I N A L S O F T H E C O N V E R T E R
DV-300 converters and RS300 line regen converters are provided only with one ground terminal which should
be connected directly to ground bus.
G R O U N D O F T H E C H O K E
The ground terminal of the choke must be connected to the
The ground terminal of the autotransformer, in case of RS300 converters must be connected to the ground bus.
SHIELD OF CABLES FOR ANALOG SIGNALS
The cables of analog signals must be shielded (each signal must be contained in the shield connected to the zero
volt terminal), the same is valid for the constant references (E.g.. For AV-300 inverters and DV-300
converters the shield must be ground connected at 360” using the omega connectors available on the support
panel of the regulation board, in front of the terminals strip on the bar above the board.
Note: cable shields are grounded at one end only.
GROUND CONNECTION OF THE ANALOG ZERO VOLT AND V REFERENCE POTENTIAL
The analog zero volt (power supply common) and the reference potential must be grounded. For devices
like AV-300, DV-300 and RS300 series the following connection on the terminal strip are needed:
terminal 11 (analog 0 V) with terminal 10 (PE)
terminal 18 V reference potential) with terminal 20 (PE)
When many devices zero volt (terminals 11 and 18) connected together, the PE connection must
be done with a 10 2 capacitor.
