Connection To The Battery; General Precautions When Working With Batteries; Connecting The Load - Victron energy Phoenix 12/180 Manuel

The inverter shuts down when the battery voltage is below 0.88xVnom or above
1.3xVnom.
Shut down and restart voltages: see technical data.

1.3 Connection to the battery

The inverters are equipped with two wires with a length of 1.5 meters. If it is
unavoidable to extend these wires, use a wire gauge of at least 1.5 times larger than
the ones supplied with the inverter. Maximum recommended battery wire length is
approx. 3 meters.

1.3.1 General precautions when working with batteries

1. Working in vicinity of a lead acid battery is dangerous. Batteries can
generate explosive gases during operation. Never smoke or allow a spark
or flame in the vicinity of a battery. Provide sufficient ventilation around the
battery.
2. Wear eye and clothing protection. Avoid touching eyes while working near
batteries. Wash your hands when done.
3. If battery acid contacts skin or clothing, wash immediately with soap and
water. If acid enters eye, immediately flood eye with running cold water for
at least 15 minutes and get medical attention immediately.
4. Be careful when using metal tools in vicinity of batteries. Dropping a metal
tool onto a battery might cause a short-circuit battery and, possibly an
explosion.
5. Remove personal metal items such as rings, bracelets, necklaces, and
watches when working with a battery. A battery can produce a short-circuit
current high enough to melt a ring or the like to metal, causing severe
burns.
CAUTION

1.4 Connecting the load

Before you connect your appliance(s) to the inverter, always check it's maximum
power consumption. Do not connect appliances to the inverter needing more than the
nominal power rating of the inverter continuously. Some appliances like motors or
pumps, draw large inrush currents in a start-up situation. In such circumstances, it is
possible that the start-up current exceeds the over current trip level of the inverter. In
this case the output voltage will quickly decrease to limit the output current of the
inverter. If the over current trip level is continuously exceeded, the inverter will shut
down and restart within 18 seconds. In this case it is advisable to disconnect the
appliance from the inverter, since it requires too much power to be driven by this
The red wire must be connected to the positive
(+) terminal and the black wire to the negative (-)
terminal of the battery.
Reverse polarity connection of the battery wires can
damage the inverter!
Damage caused by reversed polarity is not covered
by the warranty. Make sure the power switch is in the
OFF '0' position before connecting the battery.
