What this chapter contains
The appendix describes common features and mechanical installation of the optional
extension modules for the ACS355: MPOW-01 auxiliary power module, MTAC-01
pulse encoder interface module and MREL-01 output relay module.
The appendix also describes specific features and electrical installation for the
MPOW-01; for information on the MTAC-01 and MREL-01, refer to the corresponding
user’s manual.
Extension modules
 Description
Extension modules have similar enclosures and they are mounted between the
control panel and the drive. Therefore only one extension module can be used for a
drive. ACS355 IP66/67 / UL Type 4X drives are not compatible with extension
modules due to space restrictions.
The following optional extension modules are available for the ACS355. The drive
automatically identifies the module, which is ready for use after the installation and
power-up.
• MTAC-01 pulse encoder interface module
• MREL-01 output relay module
• MPOW-01 auxiliary power module.
