CAUTION<br />
RISK OF DAMAGE TO THE SOFT STARTER<br />
• Only the SH31-.../4 range can be installed inside delta connection.<br />
• Ensure connection exactly as shown on the example.<br />
• Line voltage should not exceed 440 V.<br />
• The parameter dLtA must be set to dLt.<br />
Failure to follow these instructions can result in equipment damage.<br />
