Step 6: QS link wiring
WARNING! Danger of Shock. May result in serious
injury or death.
DO NOT WIRE WHEN LIVE! Switch off
power to all power feeds via circuit breaker or isolator
before wiring or servicing the
EcoSystem Energi Savr
Node
unit.
Buttons and LEDs in the unit are used for troubleshooting.
If wiring is exposed when accessing buttons and LEDs, the
unit must be accessed by a certified electrician, following
local codes.
QS link communication uses NEC
®
Class 2/PELV wiring. Follow
all local and national electrical codes when installing
NEC
Class 2/PELV wiring with line voltage wiring.
The total length of the QS link wiring must not exceed 2000 ft
(610 m).
QS Link Wiring
Length
Wire Gauge
Available from
Lutron in one cable:
Less than
500 ft (153 m)
Power (terminals 1 and 2):
1 pair 18 AWG (1.0 mm

)
GRX-CBL-346S
Data (terminals 3 and 4):
1 pair 22 AWG (0.5 mm
2
),
twisted and shielded*
500 ft (153 m) to
2000 ft (610 m)
Power (terminals 1 and 2):
1 pair 12 AWG (4.0 mm
2
)
GRX-CBL-46L
Data (terminals 3 and 4):
1 pair 22 AWG (0.5 mm
2
),
twisted and shielded*
* Alternate Data-only cable: Use approved data link cable
(22 AWG (0.5 mm
2
) twisted/shielded) from Belden, model
#9461.
Check for compatibility in your area.
A QS system can have up to 100 zones, 100 areas, and 100 QS
devices. The
EcoSystem Energi Savr Node
unit
counts as 1 QS
device and 1-100 zones.
See diagram on the right for QS link wiring.
1. Connect terminals 1, 3 and 4 to all
EcoSystem Energi Savr Node
units.
2. Each
EcoSystem Energi Savr Node
unit
has its own built-in
power supply.
3. Terminate the terminal 2 connection (24 V
) so that each
EcoSystem Energi Savr Node
unit supplies power up to 30
Power Draw Units (PDUs). Each QS device should receive power
from only one
EcoSystem Energi Savr Node
unit.
NOTE:
To connect extra QS devices, use a separate power
supply (24 V
), and only connect COM, MUX, and MUX to the
devices connected to the
EcoSystem Energi Savr Node
unit.
4. Wiring may be daisy chained or t-tapped.
Power draw calculations are not needed for wireless inputs or
inputs connected directly to the
EcoSystem Energi Savr Node
units or
EcoSystem
ballasts.
