(1) Attach the hooks of the power cord retainer clip into the holes on the two sides
of the AC-input power receptacle.Skip this step if the power cord retainer clip is
installed on the power supply. 将电源线防脱卡钩的两头分别插入交流电源输入
插口左侧的上下插孔中。若电源模块发货时已安装卡钩，请忽略此步。
(2) Pull the power cord retainer clip leftward. 将电源线防脱卡钩扳向左边。
(3) Connect one end of the AC power cord to the AC-input power receptacle. 将交
流电源线带插孔的一端插到电源模块的交流输入插口上。
(4) Pull the power cord retainer clip rightward to secure the power cord connector
in place. 将电源线防脱卡钩向右扳，卡住交流电源线。
(5) Connect the other end of the AC power cord to the external AC power supply
system. 将交流电源线的另一端插到外置交流供电系统的插座上。

negative terminal (–) and the positive wire (+ or M/N) to the positive
terminal (+).
将PSR180-12D-B 电源线的另一端与-48V 直流供电系统相连，用负极线
（-或L）连接负极端子（-），用正极线（+或M/N）连接正极端子（+）。
