Technical Reference

Facility requirements

Check that the following requirements are met:
Environment
The drive must be protected from direct sunlight and rainfall.
Altitude
Maximum altitude for non de-rated operation is 1000 m (3281 ft).
De-rating above 1000 m (3281 ft) is 1% per 100 m (32.8 ft) of maximum nominal power.
Maximum altitude with UL approval is 2000 m (6562 ft).
Maximum altitude without UL approval is 4000 m (13 123 ft).
Ambient temperature
Activity
Operation
Operation in temperatures above 40°C (104°F) requires the SRC311
to have the output current de-rated with:
• 1.5% per 1°C (1.8°F) for IP55
• 2.5% per 1°C (1.8°F) for IP66
Storage
Humidity requirements
The relative humidity must not exceed 95% (non-condensing)
Air requirements
The air surrounding the unit must be free from:
• Excessive dust
• Acids
• Corrosive gas
• Salt

Input voltage

Depending upon the model and power rating, the drives are designed for direct
connection to the following supplies
Model Number
SRC311-X-X-XXXXX-XX
All SRC 311 monitor phase imbalance. A phase imbalance of > 3% results in SRC 311
tripping. For input supplies which have a supply imbalance greater than 3%, an input line
reactor is recommended. Alternatively, SRC 311 can be operated as a single-phase supply
drive with 50% de-rating.
