3.16.1 rCD Protection For Motorhome / Caravan / Vehicle Application
wArning!
1. When this unit is installed in a motorhome / caravan please ensure that appropriate residual Cur-
rent Devices (rCD) are installed as recommended in the typical installation diagram at fig 3.14.
2. Installation shown in fig 3.14 is based on Section 721 of british Standard bS 7671 : 2008.
3. Please Ensure that your installation complies with the national / local Electrical Codes.
Attention!
1. Lorsque l'appareil est installé dans un camping-car / caravane s'il vous plaît assurer que les dispositifs appropriés
résiduels ACTUELLES ( RCD ) sont installés ainsi comme recommandé dans le schéma d'installation typique à la
figure 3,14.
2. L'installation de la figure 3,14 est basée sur l'article 721 de la norme britannique BS 7671 : 2008.
3. S'il vous plaît assurez-vous que votre installation se conforme aux codes électriques nationaux / locaux.
3.16.2 requirement of Deep Cycle, Auxiliary battery And battery isolator For
Powering inverters in Mobile installations
basic information on Lead Acid batteries is given in Section 1.4 under "general
information - Lead Acid batteries".
For details, read on-line white Paper titled "batteries, Chargers & Alternator" at:
www.samlexamerica.com (home > Support > white Papers).
A motorhome / caravan / vehicle has Starter, Lighting and Ignition (SLI) battery. As explained in
White Paper titled "batteries, Chargers and Alternators", SLI batteries are designed to produce
high power in short bursts for cranking.
SLI batteries use lots of thin plates to maximize the surface area of the plates for providing very
large bursts of current (also specified as Cranking Amps). This allows very high starting current but
causes the plates to warp when the battery is cycled. Vehicle starting typically discharges 1%–3%
of a healthy SLI battery's capacity. The automotive SLI battery is not designed for repeated deep
discharge where up to 80% of the battery capacity is discharged and then recharged. If an SLI
battery is used for this type of deep discharge application, its useful service life will be drastically
reduced. Hence, this type of battery is not recommended for the storage of energy for inverter
applications. A second deep cycle auxiliary battery must be installed in the motorhome / caravan /
vehicle for powering the EVO
When the second auxiliary deep cycle battery is used, a battery Isolator is required that will al-
low parallel connection of the two batteries for charging when the alternator is ON and discon-
necting the parallel connection when the alternator is stopped (Isolator is shown in fig. 3.14).
The capacity of the battery Isolator should be as follows:
— For eVo-2012e: 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
— For eVo-2224e: The maximum continuous DC current required is 133A. The capacity of
the battery Isolator should be more than 133A or more than the capacity of the alternator,
whichever is higher
