UL 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.
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:
• 240 V maximum for DH1-32 models
• 500 V maximum for DH1-34 models
• 600 V maximum for DH1-35 models
Circuit breaker and fuse sizes
The adjustable frequency drive’s connections to input power must
include UL listed inverse time circuit breakers with 600V rating, or
UL listed fuses.
Terminal tightening torque and wire size
The wire size range and tightening torque for field wiring terminals
are presented.
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
DH1 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,
