1. To protect the operators, the wire connected to the GND terminal
( ) must be connected to the earth. Under no circumstances
shall this DC power supply be operated without an adequate
ground connection.
2. Installation of the power cord must be done by a professional and
compliant with local electrical codes.
1. Be sure to select an appropriate withstand voltage cable based on
the varied input voltage.
2. To ensure the operation safety, follow the input power source during
installation to select the current rated breaker that closes to each
phase and connect it to the input terminal in series.
3. The breaker should be installed inside the building. See Table 2-3
for the rating.
Table 2-1 lists the conductor sectional area for safe use of the input current and anti-pulling
wire diameter.
