Power Supply
Wiring
Gateway - LTE or Ethernet
The Zurn Z-PWRSUP-W1 provides screw terminals for the
purpose of connecting to both the upstream 120VAC branch
circuit and the downstream low-voltage DC (Class II) circuit. To
protect these live contacts, the power supply should be installed
in an appropriate enclosure including all recommended cable
clamps, conduit connectors, etc. in accordance with applicable
local electric code.
The supply will t diagonally into a standard 4-11/16” square
metal junction box. A 6” square metal junction box is sucient to
house two supplies side-by-side if necessary. Ensure the supply
is securely mounted within its enclosure so that shifting cannot
occur.
Dimensions: 2 1/8” W x 4 3/8” L x 1 5/16” H
Important: The Z-PWRSUP-W1 power supply is not for
residential or consumer use. Please install junction box and
power supply in dry locations only.
Each Zurn Smart Occupancy Light consumes a maximum of 150mA; a run of 40 lights, for example, would consume a maximum of
6A. Zurn recommends wiring the downstream low-voltage DC circuit (from power supply to light) using plenum-rated 2-conductor cable
sized according to the overall distance and maximum current load in accordance with applicable local electric code. Voltage drop in
the overall run must not exceed 1V at max load. Do not exceed 6A (40 lights) of total load per supply. If using stranded wire, Zurn
recommends using appropriately sized crimp-on ferrules at all terminations to ensure connection integrity and to prevent accidental
short-circuit conditions.
Power
Connect the ZGW-WRP-W1-LTE or ZGW-WRP-W1-ETH
gateway to a standard wall socket using the included power
supply as shown on the right.
Placement
LTE Gateway: The ZGW-WRP-W1-LTE wireless gateway uses
a cellular wide-area-network connection. To improve quality,
place the gateway away from large metallic structures or sources
of signicant electrical interference like large transformers,
motors, or orescent lighting ballasts.
Ethernet Gateway: The ZGW-WRP-W1-ETH gateway requires
connection to an Ethernet cable. Ethernet port is adjacent to the
power connection on the gateway.
Zurn Smart Occupancy Lights: The Zurn Smart Occupancy Light system uses wireless mesh communication. Zurn Smart
Occupancy Lights will communicate wirelessly with the gateway; if necessary, they will use another Zurn Smart Occupancy Light as
a relay. The gateway should be located no more than 60ft away from the nearest Zurn Smart Occupancy Light, and no Zurn Smart
Occupancy Light should be located more than 60ft away from either a gateway or another Zurn Smart Occupancy Light relayed to the
gateway via wireless mesh network.
Setup
On connection to power, the gateway will attempt to connect rst to the cellular or Ethernet network, then to the cloud.

Install Your Zurn Smart Occupancy Lights
Step 1
First, nd the center of the doorway in the relation to the ceiling
that you intend on mounting the light to. Once you have located
the center of the doorway you will need to measure out from the
center line by approximately 6 inches to the inside of the stall,
from the center point of the doorway. See image on the right.
Drill a 1/2” hole in the ceiling surface to allow for the power
cables to run though.

Step 2
When installing the ceiling mount bracket, it is very
important to ensure that the arrow is pointing toward the
inside of the stall, perpendicular to the stall door. In most
cases, the arrow should be pointing directly towards the
water closet. In some dierent stall congurations, such as
handicapped/ADA stalls, the arrow may not point directly
towards the water closet.
Once you have the arrow pointing towards the inside of the stall,
secure the ceiling mount bracket in-place with 4 x #8 screws or 4
x M4 screws. Be careful not to over-tighten the screws to mitigate
any ceiling or mount damage.

Step 3
It is crucial that the cables you install are longer than the
extension tube that is being used. Ideally the length of the wires
should be 4 inches longer than the extension tube to make the
installation easier when connecting to the power block.
Step 4 - If Using Zurn Smart Occupancy Light Mount / Extension Pole
The ceiling mount bracket is now installed and it’s time to assemble the unit.
If using a Zurn Smart Occupancy Light Mount - Extension Pole, feed the power cables though the extension tube until you see them
visibly protruding out of the bottom extension cone.
Orient the extension pole mount (arrow located in the bottom of the extension cone) to an 11 o’clock position with the ceiling mount
bracket arrow already installed at a 12 o’clock position on the ceiling. Twist the extension tube onto the ceiling mount until the arrow
points towards the inside of the stall.
The arrow on the exposed end of the extension pole can be lined up with the WC sticker by rotating the tube when attached.

Step 5
Connect the power block to the cables.
The power block is located inside the top of the Zurn Smart
Occupancy Light. Both connections are linked so either side can
be used for a single light or both sides when daisy chaining the
lights o a single power supply.
Note: When daisy chaining multiple lights o one power supply,
each light must be installed to maintain electrical connection
for the entire network of lights. If a light needs to be replaced, it
is best to remove the old light when a new one is available for
replacement. You may alternately install multiple lights using a
hub and spoke method.

Trouble Shooting
Problem Possible Cause Corrective Action
One or more lights in a
chain do not turn on when
power is applied
Incorrect Wiring Polarity Devices wired incorrectly will not be damaged, but will not power on.
Daisy-chained devices downstream of the polarity inversion may also
not function.
Verify wiring polarity matches markings on power input terminals.
Short Circuit Power supply Z-PWRSUP-W1 is protected against short circuit
conditions and will automatically disable power output when such a
condition is detected. If this is the case, no devices attached to the
short-circuited supply will function.
Beginning with the power supply and working down the chain of lights,
inspect power terminals for stray wires or other material causing
a short circuit. Zurn recommends use of crimp-on ferrules for all
connections when using stranded wire.
Light appears unexpectedly
dim and/or light appears

expected
Low Voltage Measure input voltage at xture and ensure voltage is between 11.4 V
and 12.6V.
If voltage measured is out of range, measure voltage at power supply
and ensure output is within range stated above.
If supply voltage is within range, ensure wiring used is sucient to
carry max current (150mA * total # of lights) per local code (excessive
voltage drop may be caused by insucient wire gauge).
If voltage at supply is low, disconnect lights from output terminals at
power supply and measure open-circuit voltage.
If open-circuit voltage is normal, inspect downstream wiring and
connections for possible short-circuit conditions.
If open-circuit voltage is low, replace power supply.
One light in a chain does
not turn on when power is
applied
Damaged Device Measure voltage at device power input terminals. If voltage is nominal
and device does not power on, replace device.
