Cautions, Warnings and Instructions
Wiring Warnings for Electrical Practices and Wire Sizes
The Cautions, Warnings, and instructions in this section summarize the
procedures necessary to ensure an inverter installation complies with
Underwriters Laboratories
®
guidelines.
Circuit Breaker and Fuse Sizes
The adjustable frequency drive’s connections to input power must include
UL Listed inverse time circuit breakers with 600 V rating, or UL Listed fuses as
shown in the table below.
Terminal Tightening Torque and Wire Size
The wire size range and tightening torque for field wiring terminals are
presented in the table below.
Wire Connectors
Motor Overload Protection
MMX
adjustable frequency drives provide solid-state motor overload protection,
which depends on the proper setting of the following parameter: P7.2 “current
limit“.
Set the rated current [Amperes] of the motor(s) with the above parameters.
The setting range is 0.2 * rated current to 2 * rated current,

.
Warning!
Use 60/75 °C Cu wire only or equivalent.
Warning!
Open Type Equipment.
Warning!
Suitable for use on a circuit capable of delivering not more than
5,000 rms symmetrical amperes:
• 120 V maximum for MMX11 models.
• 240 V maximum for MMX12 and MMX32 models.
• 480 V maximum for MMX34 models.
Warning!
Field wiring connections must be made by a UL Listed and CSA
Certified ring lug terminal connector sized for the wire gauge being
used. The connector must be fixed using the crimping tool specified
by the connector manufacturer.
Warning!
When two or more motors are connected to the inverter, they cannot
be protected by the electronic overload protection. Install an external
thermal relay on each motor.
