The method how to connect SIG1000 DC power supply line in the SIG9280E and SIG100

Publication Date:  2012-10-19 Views:  185 Downloads:  0

Issue Description

An office site, equipment room is DC power supply, rack not deploy unified power supply, power supply cable is 35 square millimeter from the cabinet, SIG1000 DC power module interface is special interface, can't direct connect 35 square cable, the SIG1000 supporting power cable is very thin, can not directly connect and 35 square able bare wire.

Alarm Information


Handling Process

According to the basic knowledge of parallel connection, the the power supply of power cabinet is 32A, would guarantee the power supply circuit current not less than 32A. According to the following steps:
1, connect SIG delivery-attached power line to the empty end, replace the OT end;

2, connect the power cable and SIG9280E power supply circuit together;

As below:

Root Cause

  The delivery-attached power cable is very thin, 35 square cable is thick, forced connect, will have the following problems:
1, 35 square cable power supply current is 32A, cable is thick, and the resistance is small, and SIG1000 delivery-attached power cord is very thin, resistance is big will become a "heating wire", cause potential safety problems;
2,thick and thin line forced connection, the connection place will be loose, it is easy to cause the resistance changing constantly, power supply instability, cause equipment aging.


This kind of connection to solve two problems:
1,thick and thin cable direct connection;
2, power supply thin wire resistance is too large and high fever.
