For eVo-3012e:
The maximum continuous DC current required is 373A. The capacity of
the battery Isolator should be more than 373A or more than the capacity of the alternator,
whichever is higher
For eVo-4024e:
The maximum continuous DC current required is 266A. The capacity of
the battery Isolator should be more than 266A or more than the capacity of the alternator,
whichever is higher
3.16.3 requirement to keep the neutral Conductor of Shore Power isolated
From the Chassis ground of the Motorhome / Caravan / Vehicle
As per Section 721 of british Standard bS 7671 : 2008 the neutral conductor in electrical
installations in motorhomes / caravans / vehicles is not bonded to the "chassis
" of
the motorhome / caravan / vehicle.
The Neutral is floating with respect to the "chassis
".
This is necessary for safety because if the Neutral was bonded to the chassis of the rV and if
the Neutral and the Hot got reversed by mistake, the chassis of the rV will be at 230 VAC with
respect to the Earth Ground. If a person standing on the Earth Ground touches the chassis of the
rV, he will be fed with 230 VAC and will receive electrical shock!
3.16.4 typical Mobile installation
fig. 3.14 illustrates a typical installation on motorhome / caravan / vehicle using 230VAC, 16A
Service Inlet for 16A motorhome / caravan / vehicle Power Supply Cord. The installation is based
on Section 721 of british Standard bS 7671 : 2008. Please check that your installation complies
with the national and local Electrical Codes.
Auxiliary battery is connected to the DC input connections through an appropriate fuse
to protect the DC input cables against short circuit
Auxiliary battery will be charged by the alternator through the battery Isolator
battery Temperature Sensor Model bTS-EVO is installed on the Positive or Negative post
of the auxiliary battery and connected to the port for the Temperature Sensor
Supplementary battery charging is being carried out through a solar array and a
Charge Controller connected to the DC input provided for external battery charger
AC input to the EVO
TM
is fed from typical 230VAC, 16A Power Inet (through suit-
able double pole breaker and rCD (residual Current Device) and from the generator
(through suitable breaker and rCD)
AC output from the EVO
TM
is fed to the double pole Distribution Panel board for loads
backed up by EVO
TM
Automatic Generator start/stop is possible as follows (Please see fig 3.14):
- Start operation is initiated by closure of "No" and "Common" contacts of the Status
relay (14, fig 2.1) when the battery voltage drops to the programmed value of the
Low Voltage Alarm. Stop sequence is initiated by opening of above contacts when the
battery voltage rises to the programmed “restart Value”. Please refer to programming
of "relay function"on page 29, Section 4.8 of EVO-rC Manual at Appendix A.
- Contact closure/opening signal is fed to the optional Generator Auto Start/Stop
Module which in turn feeds required start stop signals to the generator (the
generator should be capable of remote start/stop function).
When using generator, please ensure the following (please see fig 3.14):
-
Neutral of the generator is bonded to the chassis of the generator either internally
or externally through the Earthing Terminal "EG" and the chassis of the generator
is bonded to Main Earthing Terminal "M" on the motorhome / caravan / vehicle.
