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
Warning!
"Use 60/75 °C Cu wire only" or equivalent.
Warning!
"Suitable for use on a circuit capable of delivering not more
than 5,000 rms symmetrical amperes, 240 V maximum."
For DF5-322 and DF5-320 models.
Circuit Breaker and Fuse Sizes
The inverter'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
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.

Motor Overload Protection
Moeller DF5/DV5 inverters provide solid state motor overload
protection, which depends on the proper setting of the following
parameters:
• B012 "electronic overload protection"
• B212 "electronic overload protection, 2
Set the rated current [Amperes] of the motor(s) with the above
parameters. The setting range is 0.2 * rated current to 1.2 * rated
current.
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.
