One thermostatically controlled cooling fan (18, Fig 6.1c) has been provided for forced air
showing AC output V, A, Hz, W, VA and Power factor. It also has LED indications similar to

The unit can be switched oN/off from a remote location using external, wired oN/off When the unit is switched ON, all the circuitry inside the inverter becomes alive and the
control arrangements as shown in fig 8.2(a), (b) and (c). Details are given below: AC output is made available. In this condition, even when no load is being supplied (or, if a
load is connected but has been switched OFF), the inverter draws a small amount of current

When the inverter is switched OFF using the optional external Remote Control
RC-300, there will be a very minor current drain of up to 3mA for the 12V ver-
sion of the inverter and up to 5mA for the 24V version of the inverter. There will
be NO drain from the battery when the inverter is switched OFF as follows:
