3.18 MOBILE INSTALLATION - GENERAL INFORMATION
3.18.1 GFCI Protection for Vehicle Application
When EVO-1212F-HW / EVO-1224F-HW is installed in vehicles, it is to be ensured that Ground
Fault Circuit Interrupter(s) [GFCI] are installed in the vehicle wiring system to protect all branch
circuits. EVO-1212F and EVO-1224F come with Duplex GFCI, NEMA5-15 outlet.
WARNING!
Please ensure that when using hard-wired versions EVO-1212F-HW, Ground Fault Circuit
Interrupter(s) [GFCI] are installed in the vehicle wiring system to protect all branch circuits.
GFCIs listed in Table 1.5 have been tested to operate satisfactorily and are acceptable.
MISE EN GARDE!
Veuillez vous assurer que lors de l'utilisation de versions câblées EVO-1212F-HW, Disjoncteur(s) [FUITE] sont
installés dans le système de câblage du véhicule pour protéger tous les circuits de dérivation.
Des disjoncteurs de terre ci-dessous ont été testé. Leur fonctionnement est acceptable, Table 1.5.
3.18.2 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).
An RV / 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 specied 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
RV for powering the EVO
TM
(Deep cycle, auxiliary battery is shown in Figs 3.14 and 3.15).
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 Figs 3.14
and 3.15). The capacity of the Battery Isolator should be as follows:
• For EVO-1212F / EVO-1212F-HW: The maximum continuous DC current required is 152A.
The capacity of the Battery Isolator should be more than 152A or more than the capacity of
the alternator, whichever is higher.
