Ac Wiring - Latronics LS-2012 Instruction Manual

INSTALLATION

AC Wiring

●
Make sure the inverter is switched OFF before working on the mains wiring. Turn the circuit
breaker switch into OFF position.
●
Ensure that the a.c. wiring is separated from the d.c. wiring to reduce the occurrence of noise
in the installation.
●
In standard Latronics inverters the active and neutral of the 240V a.c. output are electrically
isolated from the battery negative, battery positive, and earth connections.
●
The inverter a.c. output is connected directly to the transformer output winding.
● Standard Latronics inverters have the a.c. output (active and neutral) floating with respect to
the d.c. and earth. The earth connection is connected to the case only. This configuration
provides the highest level of safety and most flexibility for installation wiring.
●
The protective earthing connection should be attached to the earth terminal of the a.c.
output junction box.
●
When using an inverter with a transfer switch ensure that no highly inductive or capacitive
loads are present such as pumps, compressors or similar. The reason for this is that transfer
from an unsynchronised source can produce large spikes that can feed back onto the
inverter and damage it.
●
Ensure that power will never be fed into the inverter a.c. output junction box from
the mains or generator. This would result in the destruction of the unit and will not be
covered by warranty.
●
Latronics inverters are suitable for use with type A and type B RCD's.
●
Latronics inverters are suitable for MEN connection.
●
The earth is connected internally to the inverter case.

WARNING
The inverter output is just as lethal as normal mains electricity.
It is important that all wiring complies with the requirements of the
relevant wiring standards. Any electrical work carried out on a.c./mains
wiring and d.c. wiring is to be performed by suitably qualified electrical
worker.
Systems with solar panels, when exposed to light, supply d.c. voltage.
