Energi Savr Node
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 before wiring
or servicing the Energi Savr Node unit.
Buttons and LEDs in the unit are used for programming
and troubleshooting. If line voltage shield is removed, the
unit must be accessed by a certified electrician, following
local codes.
QS link communication uses NEC
all local and national electrical codes when installing NEC Class
2/PELV wiring with line voltage wiring.
The total distance of the QS link wiring must not exceed
2000 ft (610 m).

Check for compatibility in your area.
A QS system can have up to 100 zones and 100 devices. The
Energi Savr Node unit counts as 1 device and up to 4 zones.
See diagram on the right for QS link wiring.
1. Connect terminals 1, 3 and 4 to all Energi Savr Node units.
2. Each Energi Savr Node unit has its own built-in power supply.
3. The terminal 2 connection (24 V
devices sharing that connection.
– Ensure that QS devices powered from terminal 2 of the En-
ergi Savr Node unit do not consume a combined total of more
than 14 Power Draw Units (PDUs).
– Refer to the documentation for each QS device to determine
that device's PDU consumption.
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 Energi Savr Node unit.
4. Wiring may be daisy chained or t-tapped.
Power draw calculations are not needed for wireless sensors or
sensors connected directly to the Energi Savr Node units.

NEC Class 2/PELV Terminal Connections
Each low-voltage NEC Class 2/PELV terminal can accept only
two 18 AWG (1.0 mm 2 ) wires. Two 12 AWG (4.0 mm
tors will not fit. Connect as shown below using appropriate wire
connectors.
