COM0011 ABB Intelligent spare parts module of control card

Description

COM0011 The two AC/DC input power supplies have 6 terminals for user connection. The connection description is as follows:
AC power connection
Live wire, neutral wire and ground wire from 120VAC power supply or L1, L2 and ground wire from 240VAC power supply pass through
The three terminals on the top of the terminal strip on the front of the power supply are connected to the system.

DC power connectionConnect the+and – wires of 125VDC (theoretical value) power supply to the two terminals on the top of terminal connector COM0011
The connection of the input power supply is not polarity sensitive. (However, only DC input type power supplies are polarity sensitive and will be
Discussed later in this chapter)
Input overvoltage protection device
This information applies to all series 90-30 power supplies except IC693PWR322 and IC693PWR328. This power supply
COM0011 overvoltage protection device of is connected to the 4th pin inside the user terminal strip. This pin is usually connected through the provided jumper
The wire (installed in the factory) is connected to the frame ground (pin 3). If the overvoltage protection is not required or supplied
Reverse current, this feature can be canceled by removing the jumper wire of pin 3 and pin 4.
If you want to use Hi pot to test this power supply, you need to remove the terminal strip jumper to cancel the overvoltage protection during the test
After the test, reinstall the jumper to recover the overvoltage protection.
Input power/current calculation
■ Determine the total output load according to the typical specifications of each module listed in Chapter 2 and Chapter 3
■ Use the above curve to determine the average input power
■ The input power is divided by the working power supply to determine the input current demand
■ Use the lowest input voltage to determine the maximum input current
■ Consider the initial inrush current demand
■ It is allowed to change the affluence (10%~20%)
Use the following procedure to determine the input power demand of the 24 VDC COM0011 high capacity power supply:
■ Determine the total output load according to the typical specifications of each module listed later in this chapter
■ Multiply the output power by 1.5 to determine the input power value
■ Input power divided by working power to determine input current demand
■ Use the lowest input voltage to determine the maximum input current
■ Consider the initial inrush current demand
■ Allowance for changes in affluence (10% to 20%)
Field wiring connection of DC input power only
DC power connection
The+and – wires of the DC power supply are connected to the two terminals on the top of the terminal strip+ The wire should be connected to the top terminal screw
Up, – the line is connected to the second screw (counting from top to bottom). The ground wire is connected to the third screw. Front of power supply
Clearly marked connection diagram.
Isolated 24 VDC power output connections
The two terminals at the bottom of the power terminal strip provide connections to isolated+24 VDC outputs, which can be used externally
The loop provides the power supply (within the power limit of the power supply).
