regulations at the site and comply with the following description:
The input power cords of the power supply must match the maximum input current and
maximum charging current shown in the table below, including the power rating of the
power supply and the AC input voltage.
Output and bypass cables must be matched to the rated output currents given in the
table, including the power rating of the power supply and the AC output voltage.
Battery cables must be matched to the discharge current of the battery at the voltage at
the end of discharge indicated in the table, taking into account the power rating of the
power supply.
The terminal block is equipped with screw connections. Select the appropriate cable

Warning
The power supply needs to be connected to the PE protective conductor. Incorrect
connection of the protective conductor may cause malfunction of EMI filters and result in
electric shock or fire.
The terminal strip for connecting power / receiving cables is located on the front for the
HS 205 housing and on the back of the power supply unit for HS 305 and HS 505.
