5.3.16 Input Power Connection
Use the following procedure to connect the power supply to a single-phase, grounded, 3-
wire, 50 Hz or 60 Hz 200 V to 230 V power source.
WARNING High Voltage Hazard
Ensure all electrical power is off when wiring input power to your DCX
S Power Supply connector block.
To prevent the possibility of an electrical shock, ground the power
supply by securing an 8 gage grounded conductor to the ground
screw located next to the air outlet.
WARNING High Voltage Hazard
If miss-wired, the power supply can present an electrical shock
hazard.
NOTICE
The power supply can be permanently damaged if it is connected to
the incorrect line voltage, or if the connection is mis-wired.
Table 5.12 Input Power Connection
Step Action
1 Detach the connector block on the back of the power supply.
2
Use three properly sized wires (No. 12 gage, 2.5 mm or according to local
standards) to connect the line 1, line 2, and ground to the connector block as
shown on Figure 5.6 DCX S Power Supply Connections (Horizontal Model).
Choose wires according to the current rating as specified in Table 5.2 Input
Current and Circuit Breaker Specifications and on the label located on the
back of the unit. Be sure to use agency approved wiring and use sleeving or
tubing on each wire for double insulation.
3
Use cable ties to secure the wires to the connector block metal piece. This
will help to prevent the line and ground wires from becoming loose and will
also act as a strain relief.
4
Secure an 8 gage grounded conductor to the ground screw located next to
the air outlet.
