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.
NOTICE
Use 60/75 °C Cu wire only or equivalent.
NOTICE
Open Type Equipment.
NOTICE
Suitable for use on a circuit capable of delivering not more than
5,000 rms (AS) symmetrical amperes has:
– 240 V maximum for DA1-12 and DA1-32 models
– 480 V maximum for DA1-34 models
Circuit Breaker and Fuse Sizes
The variable frequency drives' 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.

NOTICE
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
DA1 variable frequency drives provide solid-state motor overload protection,
which depends on the proper setting of the following parameter:
P1-08 "current limit".
Set the rated current [Amperes] of the motor(s) with the above parameters.
The setting range is 25 % rated current to 100 % rated current,
→ manual MN04020005Z...
NOTICE
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.
