3.5.9 Taping Battery Wires Together To Reduce Inductance
Do not keep the battery wires far apart. Keep them taped together to reduce their inductance.
Reduced inductance of the battery wires helps to reduce induced voltages. This reduces ripple in the
battery wires and improves performance and efficiency. For details, refer to Limiting Electro-Magnetic
Interference" at Section 1.3.4.
3.6 AC INPUT AND OUTPUT - LAYOUT AND CONNECTION ARRANGEMENT
3.6.1 AC Input and Output Connections for EVO-1212F and EVO-1224F
3.6.1.1 AC Input Connection: Grid AC input is fed through 20A AC Inlet Plug Connector –
IEC60320 C-20 (9, Fig 3.9.1). Use NEMA 20A-125 VAC detachable Power Cord [NEMA5-20
Plug for connecting to the 120VAC Outlet and IEC60320 C-19 Socket Connector on the other
end for connection to the Inlet Plug Connector (9, Fig 3.9.1)].
For convenience, IEC60320
C-19 socket connector has been provided. (See Section 2.6 - Contents of Package).

3.6.1.2 AC Output Connection Through Ground Fault Circuit Interrupter (GFCI)
An un-intentional electric path between a source of current and a grounded surface is referred
to as a “Ground Fault”. Ground faults occur when current is leaking somewhere. In effect,
electricity is escaping to the ground. How it leaks is very important. If your body provides a path
to the ground for this leakage (dry human body has a low resistance of only around 1 K Ohm),
you could be injured, burned, severely shocked or electrocuted. A Ground Fault Circuit Inter-
rupter (GFCI) protects people from electric shock by detecting leakage and cutting off the AC
source. The leakage detection circuit compares the current sent to the load and returned back
from the load. If the returned current is less by 5 to 6 mA due to leakage, the GFCI trips. The
GFCI also trips if it sees Neutral to Ground bond on the load side of the GFCI.
The AC output of EVO-1212F and EVO-1224F is available through a NEMA5-15R GFCI Duplex
Receptacle (10 in Figs 2.1 and 3.9.1). The Neutral slot of this receptacle (longer rectangular slot)
is internally bonded to the metal chassis of the inverter.
Self Monitoring GFCI: The GFCI is “Self Monitoring Type” as per UL Standard Ul-943. As soon
as the Inverter is switched ON and 120 VAC is available on the internal Line Side of the GFCI,
Red LED marked “Life End Alarm” (10c in Figs 2.1 and 3.9.1) will flash once and then will
remain OFF. The Green LED (10d in Figs 2.1 and 3.9.1) will switch ON indicating that AC power
is available at the Load Side outlets.
