Wiring The Terminals
Caution
This section describes wiring for the NI PS-12/13 power supply. Table 1
provides a list of basic requirements for wiring.
Consider the following when wiring the NI PS-12/13.
•
Use appropriate copper cables that are designed for an operating temperature of:
–
60 °C for ambient up to 45 °C.
–
75 °C for ambient up to 60 °C minimum.
•
Follow national installation codes and installation regulations.
•
Up to two stranded wires with the same cross section are permitted in one connection point
(except PE wire).
•
Do not use the unit without the PE connection being wired.
Complete the following steps to connect wires to the input and output terminals.
1.
Ensure that none of the wires are connected to live power.
2.
Strip the ends of the wires according to the recommendations in Table 1.
3.
Insert the end of the wire into the screw terminal until the exposed portion of the wire is
completely inside of the terminal connection. If you are using stranded wire, ensure that all
strands of the wire enter the terminal connection.
4.
Tighten the screw terminal.
5.
Repeat steps 3-4 for each of the other terminals.
6.
Ensure that all wires are properly seated and not loose.
7.
