FAQ

Q: Can this unit operate in parallel with another 1606-XL480EP?
A: Yes, it supports parallel operation for redundancy or additional load capacity.

Q: Is it suitable for outdoor installations?
A: The unit requires an enclosed control panel. It is rated for -25°C to +60°C ambient temperatures.

Q: What distinguishes the XL480EP from newer 1606-XLE or XLS series?
A: The XL480EP has a wider footprint and slightly lower efficiency. Newer models are more compact and offer enhanced thermal management.
