Make sure each power cord has a separate circuit breaker.
请保证电源线有独立的输入断路器。
Turn off the circuit breaker before connecting the power cord.
连接电源线前，请将需要连接电源线的输入端断路器置于断开状态。
For a PSR450-12D power module, the power cord connector and the receptacle form a disorientation
rejection structure. If you cannot insert the connector into the receptacle, the orientation might be
wrong. Re-orient the connector rather than use excessive force to push it in.

电源模块的电源线时，将电源线带插孔的一
端插到电源模块的输入插口上，再用可拆卸式扎带将电源线固定到电源模块的拉手处，以防电源线脱落。
For a PSR450-12AHD power module, slide the cable clamp onto the tie mount, connect the female
connector of the power cord to the power receptacle on the power module, and then close the cable
clamp and slide it forward until it is flush against the edge of the female connector.

breaker.
将电源线的另一端插到外置交流或直流供电系统的插座上，并连通电源输入端的断路器。
③
Examine the LED on the power module. If the LED is steady green, the power cord is connected
correctly. If the LED is off or red, examine the installation and troubleshoot the problems until the LED
becomes steady green.
查看电源模块的状态指示灯，如果指示灯的状态为绿色常亮，说明电源线连接成
功。如果指示灯不亮或为红色，请仔细检查安装情况，排除各种故障后，再次尝试，直到电源模块状态指
示灯正常为止。

电源模块的电源线时，先用一字螺丝刀逆时针旋松直流电源连接器保护盖两侧的固定
螺钉，并取下连接器的保护盖，再将电源线插头插入到电源模块的直流输入插口上，用一字螺丝刀顺时
针方向拧紧直流电源线插头两侧自带的螺钉，使电源线插头固定在电源模块直流输入插口上。
To prevent the power cord from falling off, use a removable cable tie to secure the power cord to the
power module handle. For the securing method, see "PSR450-12A/PSR450-12A1 power module."
