safety Instructions
Use of external Fuse in Dc input circuit
Use UL Class T (As per UL Standard UL 248-15 / Type "HRC" as per BS88-2 or as per IEC
60269-2) or equivalent fuse of appropriate capacity within 7" of the battery Positive ter-
minal. This fuse is required to protect DC input cable run from damage due to short circuit
along the length of the cable. Please read instructions under Section 8.4.5 - Installation.
Hard Wiring of Ac output to Ac Panelboards in RVs / Motor Homes / trailers /campers
WARninG!
RiSK oF eLectRic SHocK
When this unit is installed in RV / Motor Homes / Trailers / Campers and hard-
wiring connection is used to feed the AC output of the inverter to the AC
Distribution Panelboard / Load Center in the vehicle, it is to be ensured that
the AC output is fed to the Panel board through appropriate residual Current
Detector (RCD) or Ground fault Circuit Interrupter [GfCI].

General Information
2.1. DeFinitionS
The following definitions are used in this manual for explaining various electrical
concepts, specifications and operations:
Peak Value: It is the maximum value of electrical parameter like voltage / current.
RMS (Root Mean Square) Value: It is a statistical average value of a quantity that varies
in value with respect to time. for example, a pure sine wave that alternates between
peak values of Positive 329.22V and Negative 329.22V has an RMS value of 230 VAC.
Also, for a pure sine wave, the RMS value = Peak value ÷ 1.414.
Voltage (V), Volts: It is denoted by “V” and the unit is “Volts”. It is the electrical force
that drives electrical current (I) when connected to a load. It can be DC (Direct Current
– flow in one direction only) or AC (Alternating Current – direction of flow changes peri-
odically). The AC value shown in the specifications is the RMS (Root Mean Square) value.
current (i), Amps, A: It is denoted by “I” and the unit is Amperes – shown as “A”. It is
the flow of electrons through a conductor when a voltage (V) is applied across it.
Frequency (F), Hz: It is a measure of the number of occurrences of a repeating event per
unit time. for example, cycles per second (or Hertz) in a sinusoidal voltage.
efficiency, (
η
): This is the ratio of Active Power Output in Watts ÷ Active Power Input
in Watts.
