ABB 5SHY5045L0020 SCR control unit module
What this chapter containsThis chapter describes the construction and operating principle of the drive in short.
ACS800-04/U4 product overview
The ACS800-04/U4 is an IP00 drive module for controlling AC motors. It is to be
installed into a cabinet by the customer with base or wall fastening. The input cable
terminals are located at the top of the unit whereas the motor cable terminals are
located at the left- or right-hand side of the unit. The unit is delivered pre-assembled
with mounting pedestal and output busbars.
The ACS800-04M is delivered as non-pre-assembled kits, which provide more
alternatives in assembling the units than the basic ACS800-04.
Example configurations
Motor and brake busbars on the
right-hand long side of the module
and DC busbars on the left-hand side
Output busbars on the short
side of the module
Motor and brake busbars on the
left-hand long side of the module
and DC busbars on the right-hand side
Frame size R8
Output busbars on the short
side of the module
Frame size R7
Frame size R7 with bottom exit
(optional top entry busbar
shroud and bottom exit shroud
included). Output busbars are
located at the base of the
module.

The type designation label includes an IEC and NEMA rating, C-UL US, and CSA
markings, a type code and a serial number, which allow individual recognition of
each unit. The first digit of the serial number refers to the manufacturing plant. The
next four digits refer to the unit’s manufacturing year and week respectively. The
remaining digits complete the serial number so that there are no two units with the
same serial number.
The type designation label is located on the front cover and the serial number label
inside the unit. Example labels are shown below.
The type code contains information on the specifications and configuration of the
drive. The first digits from left express the basic configuration (for example,
ACS800-04-0170-5). The optional selections are given thereafter, separated by plus
signs (for example, +E202). The main selections are described below. Not all
selections are available for all types. For more information, refer to ACS800
Ordering Information (3AFY64556568, available on request).
