Connecting the Battery and Load
4.3.2
The
battery and load connection will be made with two cables, POSITIVE and
NEGATIVE.
Take especially careful to observe the correct polarity of the cables.
I and – of the batteries will be connected to the corresponding intakes of
the
ZGR SWIT NG.
The battery serial connection is explained in the “battery series” section.
The final battery connection test consists of measuring the offset voltage, in order to check whether during
assembly the polarity of any of the elements has been inverted accidentally.
The Load provides an additional output. The output voltage and current corresponding to each of the models are
shown below:

Table 4-1 Voltage and current of each of model
The
ZGR SWIT NG allows the use of this load output while the battery is being charged (terminals on side). To do
this you must remember that
the maximum current provided by the ZGR SWIT NG must not be exceeded (see
table above). The higher the consumption current in the load terminals, the lower the battery charge (this current
may be virtually "0" if the load consumption is the maximum permitted).
Ground
4.3.3
It is obligatory to connect the unit to ground and this is done directly to the screw or terminal indicated inside the
cabinet or box.
If you have only ordered the
ZGR SWIT NG (without batteries or cabinet/box), the ground connection will go to
the input terminal as explained above 4.2.3.
WARNING
The battery terminals carry dangerous voltages, even when the
ZGR SWIT NG is not in operation. Access to
the batteries must be restricted to trained personnel. To avoid any possible damage, please follow the
instructions set out in this manual.
IMPORTANT
Pay attention to the polarity of the connection. Inversion of the + and – poles may cause serious damage to the
equipment connected.
The cable section must be correct for the maximum load current.
