Requirements for UL Compliance

Solid-State Motor Overload Protection

These devices provide Class 10 motor overload protection. The maximum internal overload
protection level (current limit) is 150% for 60 seconds in Heavy Duty mode, and 110% for 60s
in Normal Duty mode. Refer to the Software Product Manual, Chapter 1: Programming Your
Application - CURRENT LIMIT for user current limit adjustment information.
An external motor overload protective device must be provided by the installer where the motor
has a full-load ampere rating of less than 50% of the drive output rating; or when the DISABLE
STALL trip (
480 seconds (refer to the 650G Software Manual, Chapter 1 : STALL TRIP.
Motor over temperature sensing is required. Motors used in conjunction with the drive
controller shall be protected with PTC sensor(s) or relays suitable for use with the variable
speed drive. Technical details can be found in Chapter 3 Installing the Drive.

Short Circuit Rating

The following drives are suitable for use on a circuit capable of delivering not more than:
220-240V products 1 single phase 10,000 RMS Symmetrical Amperes, 230/460/500V
maximum
Frame 2: 10,000 RMS Symmetrical Amperes, 460/500V maximum
Frame 3: 10,000 RMS Symmetrical Amperes, 460/500V maximum
Frame C: 10,000 RMS Symmetrical Amperes, 230/460/500V maximum
Frame D: 10,000 RMS Symmetrical Amperes, 230/460/500V maximum
Frame E: 18,000 RMS Symmetrical Amperes, 230/460/500V maximum
Frame F: 18,000 RMS Symmetrical Amperes, 230/460/500V maximum

Solid-State Short-Circuit Protection

These devices are provided with Solid-State Short-Circuit (output) Protection. Branch circuit
protection requirements must be in accordance with the latest edition of the National Electrical
Code NEC/NFPA-70.

Recommended Branch Circuit Protection

It is recommended that UL Listed (JDDZ) non-renewable cartridge fuses, Class K5 or H; or UL
Listed (JDRX) renewable cartridge fuses, Class H, are installed upstream of the drive. Refer to
Chapter 9: "Technical Specifications" - Power Details for recommended fuse ratings.

Motor Base Frequency

The motor base frequency rating is 480Hz maximum.

Field Wiring Temperature Rating

Use 75°C Copper conductors only.

Field Wiring Terminal Markings

For correct field wiring connections that are to be made to each terminal refer to Chapter 3:
"Installing the Drive" - Power Wiring Connections, and Control Wiring Connections.

Terminal Tightening Torques

Refer to Chapter 3: "Installing the Drive" - Terminal Tightening Torques.
