3.5.1 Preventing DC Input Over Voltage
It is to be ensured that the DC input voltage of this unit does not exceed 17 VDC for the 12V battery version
EVO-1212F / EVO-1212F-HW, and 34 VDC for the 24V battery versions EVO-1224F and EVO-1224F-HW to
prevent permanent damage to the unit.
3.5.2 Preventing Reverse Polarity On The Input Side
!
CAUTION!
When making battery connections on the input side, make sure that the polarity of bat-
tery connections is correct (Connect the Positive of the battery to the Positive terminal
of the unit and the Negative of the battery to the Negative terminal of the unit). If the
input is connected in reverse polarity, external DC fuse in the input side will blow and
may also cause permanent damage to the inverter.
Damage caused by reverse polarity is not covered by warranty.
!
ATTENTION!
Quand vous faites des connexions à la batterie du côté d’entrée, veuillez assurer que les polarités sont mise
du bon côté (Lié le positif de la batterie à la borne positive de l’appareil et le négatif de la batterie à la borne
négative de l’appareil. Si les polarité de l’entrée sont mise à l’envers, le fusible CC externe du côté d’entrée va
s’exploser et peut causer des dégâts permanent à l’onduleur.
Des dégats causés par un renversement des polarités n’est pas couverts par la garantie.
3.5.3 Connection From Batteries / External Charge Controller To The DC Input
Side – Sizing of Cables And Fuses
WARNING!
The input section of the inverter has large value capacitors connected across the
input terminals. As soon as the DC input connection loop (Battery (+) terminal

Battery (–) terminal) is completed, these capacitors will start charging and the
unit will momentarily draw very heavy current that will produce sparking on the
last contact in the input loop even when the unit is in powered down condition.
Ensure that the fuse is inserted only after all the connections in the loop have
been completed so that sparking is limited to the fuse area.
Flow of electric current in a conductor is opposed by the resistance of the conductor.
The resistance of the conductor is directly proportional to the length of the conductor
and inversely proportional to its cross-section (thickness). The resistance in the
conductor produces undesirable effects of voltage drop and heating. The size (thickness
/ cross-section) of the conductors is designated by AWG (American Wire Gauge).
Conductors thicker than AWG #4/0 are sized in MCM/kcmil.
Conductors are protected with insulating material rated for specific temperature e.g.
90˚C/194˚F. As current flow produces heat that affects insulation, there is a maximum
permissible value of current (called “Ampacity”) for each size of conductor based on
