CAution!
As per American boat and Yacht Council (AbYC) Safety Standard E-11 for the AC and DC
Electrical Systems on boats, the size of DC side grounding wire shall not be smaller than one
size under that required for current carrying conductors supplying the device. Hence, for ap-
plication on EVO

the same or one size smaller than the size of battery cable specified in Table 3.1.

Attention!
Conformément « American Boat et Yacht Council » ( ABYC ) la norme de sécurité E - 11 , la taille du fil de mise a terre du côté
CC ne doit pas être inférieure à un format sous celle requise pour les conducteurs tenant le courant pour alimenter l'appareil.
Par conséquent, pour l'application EVO
même ou strictement une taille plus petite que la taille du câble de batterie indiqué dans le tableau 3.1.
As described at Section 3.13, the metal frame / chassis of the EVO
the Main Earthing Terminal "ME" for AC side grounding. It may be argued that if the metal frame
/ chassis of EVO
is it necessary to provide an additional DC side grounding wiring? (Wiring that bonds DC Ground-
ing Terminals "GE", "PE-b" and "ME" in fig 3.1). If separate thicker grounding wire of the same
size as the battery cable was not provided for the DC side grounding and there was a ground fault
in the battery circuit, very large DC fault current from battery+ would flow through the smaller
size AC grounding wires to the battery Negative through the Main Earthing Terminal "ME". These
smaller size AC side grounding wires would be damaged due to very high DC side fault current
(150A to 400A depending on the Model of the EVO
DC Side grounding Arrangement for typical Shore based installations using Protective
Multiple earthing (PMe) or "tn-C-S" earthing System (Please refer to Fig. 3.12)
A DC Side Grounding Connector (G2) (5 in the DC side layout in fig. 2.1) is provided in the
EVO . This connector is internally bonded to the metal frame/chassis of the EVO
