Energi Savr Node for 0–10 V­Energi Savr Node with Softswitch

The Energi Savr Node (ESN) family is a group of modular
products for the control of lighting, receptacles, and other loads.
This document describes the following products:

• Energi Savr Node for 0–10 V-
(models QSN-4T20-S, QSN-4T16-S-347)

• Energi Savr Node with Softswitch
(models QSN-4S20-S, QSN-4S16-S-347)

Features

• Rated to switch 20 A receptacles with any output.

• Default configuration requires no commissioning.

• Program using integral interface on the ESN unit.

• Four occupancy sensor inputs for automated control of loads in
4 zones.

• Four daylight sensor inputs automatically adjust light levels based
on the amount of natural light entering through the windows.

• Four IR receiver inputs for personal control.

• Four inputs for IEC PELV / NEC® Class 2 dry-contact switches.

• Includes QS control link for seamless integration of loads, control
stations, and QS sensor modules.

• Patented Softswitch circuit eliminates arcing at mechanical
contacts when loads are switched, prolonging relay life to an
average of 1,000,000 cycles at 16 A.

• Contact Lutron for compatibility with a Quantum system.

0–10 V- Wiring (QSN-4T20-S)

• 20 to 12AWG (0.5 to 4.0mm2)

• Strip length: 1/4in (6mm)

• Torque: 5 in-lb (0.5 N•m)

• 0-10 V- control wires for zones 1-4 can be installed using NECR
Class 1 or Class 2 wiring methods.

• 0–10 V zones 1–4 are not isolated from each other.

• Negative (–) terminals are not internally connected to each other;
both positive (+) and negative (–) connections must be made.

WARNING . Entra pment / Fire Ha zard. To avoid the risk of entrapment, serious injur y, or death, these controls must not be used to control

equipment which is not visible from every control location or which could create hazardous situations such as entrapment if operated accidentally.
Examples of such equipment which must not be operated by these controls include (but are not limited to) motorized gates, industrial doors, space
heaters, etc. It is the installer’s responsibility to ensure that the equipment being controlled is visible from every control location and that only suitable
equipment is connected to these controls. Failure to do so could result in serious injury or death.

• Follow all national and local codes for separation requirements.

• If any pair of 0-10 V- control wires are installed using NECR Class 1
wiring methods, then these wires must be physically separated from
all other Class 2 wiring in the Energi Savr Node in accordance with
NECR guidance on separation of Class 1 and 2 wires.

• If one pair of 0-10 V- control wires are wired using NECR
Class 1 wiring methods, then all pairs of 0-10 V- control wires must
be installed using NECR Class 1 wiring methods.
