SG-9500 Hardware Guide
This equipment should be located in the same immediate area (such as
adjacent cabinets) as any other equipment that has a connection
between the earthed conductor of the same DC supply circuit and the
earthing conductor, and also the point of earthing of the DC system. The
DC system should be earthed elsewhere.
The DC supply source is to be located within the same premises as the
equipment.
Switching or disconnecting devices should not be in the earthed circuit
conductor between the DC source and the point of connection of the
earthing electrode conductor.
To connect a DC power cable to a DC power source:
1.
Cut the DC power cord ends no shorter than 150 cm (59.06 in).
2.
If the power source requires ring tongues, use a crimping tool to install the
ring tongues on the power cord wires.
IMPORTANT The ring terminals must be UL approved and accommodate 10 gauge
wires.
IMPORTANT The minimum nominal thread diameter of a pillar or stud type terminal
must be3.5 mm (0.138 in); the diameter of a screw type terminal must be
4.0 mm (0.157 in).
3.
Stack each same-colored pair of wires and then attach them to the same
power source. The power cord consists of three wires (black, red, and
green).
