Overview
This chapter states the general safety instructions that must be
followed when installing and operating the MTAC-01 Pulse
Encoder Interface module.
The material in this chapter must be studied before attempting any
work on, or with, the unit.
In addition to the safety instructions given below, read the
complete safety instructions of the specific drive you are working
on.
General safety instructions
WARNING! All electrical installation and maintenance work on the
drive should be carried out by qualified electricians.
The drive and adjoining equipment must be properly grounded.
Do not attempt any work on a powered drive. After switching off
the input power, always allow the intermediate circuit capacitors
5 minutes to discharge before working on the drive, the motor or
the motor cable. It is good practice to check (with a voltage
indicating instrument) that the drive is in fact discharged before
beginning work.
The motor cable terminals of the drive are at a dangerously high
voltage when input power is applied, regardless of motor
operation.
There can be dangerous voltages inside the drive from external
control circuits even when the drive input power is shut off.
Exercise appropriate care when working on the unit. Neglecting
these instructions can cause physical injury or death.

Preparing for installation
MTAC-01 module
The MTAC-01 Pulse Encoder Interface module is an interface for
connecting a digital pulse encoder to an ACS350 drive. A pulse
encoder should be used if accurate speed or position (angle)
feedback from the motor shaft is required.
Module layout
Compatibility
The MTAC-01 module is compatible with all ACS350 drives. To
confirm compatibility with a particular pulse encoder, compare the
pulse encoder requirements to Specifications on page 25.

Installation
Installing the module
Delivery check
The MTAC-01 module package contains:
• MTAC-01 module
• grounding stand-off
• panel port adapter
• this manual.
Mounting
WARNING! Follow the safety instructions given in this manual and
in the ACS350 User’s Manual [3AFE68462401 (English)].
To mount the MTAC-01 module:
1. If not already off, disconnect the input power from the drive.
After disconnecting the input power, wait for 5 five minutes
before you start working on the drive.
2. Remove the possible control panel or panel cover from the
drive.
3. Remove the grounding screw in the top left corner of the drive’s
control panel slot and install the grounding stand-off in its place.
4. Ensure that the panel port adapter is attached to either the
panel port of the drive or the mate part of the MTAC-01 module.
5. Gently and firmly install the MTAC-01 module to the drive’s
panel slot directly from the front.
Note: Signal and power connections to the drive are automatically
made through a 6-pin connector.
6. Ground the module by inserting the screw removed from the
drive in the top left corner of the MTAC-01 module. Tighten the
screw.
