3.1.4 Parallel Connection With Copper Bars
AC distribution cabinet and rectifier cabinet are connected by cables, while parallel connections between rectifier
cabinets, between rectifier cabinet and DC distribution cabinet and between DC distribution cabinets are all achieved
by means of parallel connection copper bars. The AC/DC integrated distribution cabinet and rectifier cabinet are
connected by both cables and copper bars.
Take parallel connections between a rectifier cabinet and a DC distribution cabinet for example, the connection
procedures are as follows:
1. Remove the upper side doors between the rectifier cabinet and the DC distribution cabinet.
2. Connect the positive bars and negative bars inside the cabinet respectively by copper bars and screws, as shown
in Figure 3-6.
If users need to parallel connect the rectifier cabinets or the DC distribution cabinets, they need to contact Vertiv for
technical support.
