Installing Fuses on the Input Side

Always install input fuses to the input side of the as a protective measure against damage
caused by a short circuit.
Refer to Factory Recommended Drive Branch Circuit Protection on page 251
on input fuse selection.
u

Attachment for External Heatsink

An external attachment can be used to project the heatsink outside of an enclosure to ensure
that there is sufficient air circulation around the heatsink. This installation method still requires
a certain amount of airflow over the drive case.

Noise Filter Installation

This drive has undergone testing in conformance with IEC61800-5-1: 2007 and is in
compliance with low voltage directives.

Installing a Motor Thermal Overload (oL) Relay on the Drive
Output
Motor thermal overload relays protect the motor by disconnecting power lines to the motor
due to a motor overload condition.
Install a motor thermal overload relay between the drive and motor:
• When operating multiple motors on a single AC drive.
• When using a power line bypass to operate the motor directly from the power line.
It is not necessary to install a motor thermal overload relay when operating a single motor
from a single AC drive. The AC drive has UL recognized electronic motor overload protection
built into the drive software.
Note: Disable the motor protection function (L1-0 1 = "0") when using an external motor thermal overload
relay. The relay should shut off main power on the input side of the main circuit when triggered.
n General Precautions when Using Thermal Overload Relays
The following application precautions should be considered when using motor thermal
overload relays on the output of AC drives in order to prevent nuisance trips or overheat of
the motor at low speeds:
• Low speed motor operation
• Use of multiple motors on a single AC drive
