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
®
Class 2/PELV wiring. Follow
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).

#9461.
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 ) supplies power to QS de-
vices sharing that connection.
– Ensure that QS devices powered from terminal 2 of the Energi
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.

Each low-voltage
NEC
Class 2/PELV terminal can accept only
two 18 AWG (1.0 mm

) conduc-
tors will not fit. Connect as shown below using appropriate wire
connectors.
