CONNECTION TO POWER SOURCE & EARTHING
Caution:
U
Even though the inverter is powered from a battery, it still produces Dangerous High Voltage
AC power and has the potential to fatally injure if incorrectly installed or used.
U
Before making any connections ensure inverter is switched off and has no AC appliances
plugged into the AC output sockets.
U
Ensure vehicle / system is a negative earthed or negative ground system only.
U
Double check battery negative and positive posts before making any connection, a wrong
connection (Reverse polarity) will cause the fuse/s to blow and may damage the inverter.
U
when the inverter has not been used for some time. This spark is caused by the inverter’s large
capacitors charging quickly. To minimise this, make the last connection quickly and completely.
U
U
Batteries can be dangerous, follow all battery manufacturer’s instructions and warnings.
U
Projecta inverters are designed FOR INDEPENDENT USE ONLY. That is, they cannot be
connected to household wiring whether the building is connected to the electricity grid or not.
U
Never operate the inverter without the DC negative input connected direct to the battery and
never install a fuse, circuit breaker or battery switch in the negative supply line
(IM150 excepted).
P/No. IM150
Making the DC connection on the IM150 is easy with the supplied lead and accessory
(cigarette) plug:
U Insert the accessory plug into your vehicle’s 12 Volt accessory (cigarette) socket.
You may need to turn the ignition key to the “Accessory” position to energise the socket and
provide power to the inverter.
U The IM150 does not need any external earthing, however an external earth connection
(Chassis GND) has been provided on the rear panel, this connection can be used to help reduce
radio / TV interference, see the section on external earthing.
P/No. IM300, IM600, IM1000 & IM2000
These inverters can be connected to a power source on a temporary basis with the supplied
DC leads (see the section Temporary Connection) or hard wired for a permanent installation
with suitably sized cable and hardware for your application (see the section Hard Wired
Connection). Regardless of which connection method is used it may be advantageous to earth
the inverter case, see the section on External Earthing for more details.
