Th CSX400-DC requires either a 48 Vdc or 60 Vdc (48/60 Vdc), 3.5 A (maximum), external power
source supplied by three 18 AWG (American Wire Gauge) copper wires. These wires must be
terminated to the dc input power strip shown in Figure 20 with either ring or spade terminals. The
dc power supply in the CSX400-DC has its own on/off switch and is rated at 100 watts. To connect
the CSX400-DC to a 48/60 Vdc power source, face the back panel, then refer to Figure 20 and
proceed as follows:
ONLY QUALIFIED PERSONEL SHOULD PERFORM THESE INSTALLATION
PROCEDURES.
