Purpose
Wiring enclosure holds PDMs and protects
equipment from physical damage. Enclosures should
be placed in conditioned space as per the
environmental specifications.
Platform base for termination of up to 16 field wires
via RJ45 Ports. LED Driver and Switching modules
plug into 16 Port Sockets.
LED Drivers inserted into PDM Port Sockets provide
constant current power to LED Luminaire fixtures
connected to the SIBs at the far end of the wires.
Typically, one driver is required for each fixture.
Some fixtures below 7W can be run in Series up to 3
per driver (refer to fixture specs). The on/off/dim
state of the driver is controlled by signals received
from a SwitchPuck over the selected PDM Channel.
Constant voltage power is used for some multi-bulb
fixtures and strip lights where the total current
depends on the number of bulbs or the length of the
strip. Control signal is received from the PDM
Channel.
SwitchPucks read dry contact and analog signals from
field switch inputs and produce a PDM Channel
control signal. Up to 96 LED Drivers can listen to that
Channel and be controlled by the switch inputs. This
is how “zones” of lights are grouped to together with
switches. SwitchPucks are also controllable via the
PDM Comm Bus allowing third-party controllers to
set the output level of lights and read the status of
light levels.
Provides 12V DC regulated power to SwitchPucks.
This power is also shared with the 16 PDM Ports
allowing smart devices connected to the SIB
Accessory Power pins to remain powered regardless
of the LED Power state.
A simple interface for connecting LED Power Output,
12V Accessory Power Output, and Switch signal input
to a PDM Port and Port Socket. Some lights and
Switches have the SIB component built-in and
require no additional connections beyond the Cat5
field wire. The L-SIB-K contains a screw terminal for
LED Power output and an optional wire harness for
connecting Accessory Power and Switch Input.
L-SIB-SE is a multi-purpose SIB simplifying connection
of Constant Current LEDs and/or Switch Inputs. It
also makes Series connections easy when 2-3 share a
single PDM Port. See fixture specs when this is
allowed.

LibRE System Installation Guide
Lights
Constant Current LED Luminaries contain no driver
circuits. A SIB connects the LED array to the Driver
inserted in the PDM Port Socket via the Cat5 wire
attached to the PDM Port.
Switch Inputs
Provide signals to SwitchPucks inserted in PDM Port
Sockets indicating what channel output level is
desired. Momentary contact switches provide the
most flexibility but simple on/off switches are
acceptable. Only a tiny control voltage passes
through the switch inputs. DO NOT connect AC
Power or AC Dimmers to LumenCache.
Occupancy detectors produce a 7.5kOhm resistance
across the C and S pins on the SIB when occupancy is
detected. Modes 3-6 detect the change from
Unoccupied to Occupied and from Occupied to
Unoccupied. Modes 1 & 2 use the occupancy
detector as a simple switch. Some have ambient
light detection features.
Breakers protect PDMs from enclosure wiring faults
between the battery and the PDM input block.
Occupancy Sensor Inputs
DC Breakers
Batteries
Chargers & Power Supplies
Batteries provide backup power, primary power, and
power smoothing. Constant Current LED drivers are
unaffected by fluctuations in their supply voltage
that cause flicker, winks, and ripples in traditional AC
lighting.
Provide charging and maintenance of the batteries.
Chargers must be sized to provide sufficient current
for full load from the lights and a little extra to
recharge the batteries in the event they are
depleted.
3 Power Requirements and Field Wiring
3.1 PDM Supply Power Requirements
Each PDM requires 11.0-13.8V DC power at up to 15A. They are connected to the battery via a DC Breaker on
the POSITIVE terminal only.
NEVER CONNECT AC POWER DIRECTLY TO ANY LUMENCACHE COMPONENT.
All Negative power input terminals must be connected together with no circuit interrupters or disconnects in
between.
The Battery must be capable of supporting the total current draw of a fully loaded enclosure. With 6 PDMs in
an enclosure, this is 90A at 12V.
0000000 rev 0.1
Page |5
LibRE System Installation Guide
The main Power Supply may be a solar, wind or other renewable charger, or an AC/DC battery charger.
AC Mains-connected Chargers and Power Supplies must provide sufficient Isolation from AC Mains.
Acceptable power supplies must be certified to meet UL1564 or UL60950-1 safety standards and
environmental conditions of the room where the enclosure is located.
3.2 Field Device Cabling Requirements
3.2.1
General Wire Requirements
Each SIB can be connected to the PDM Port using standard Category Wire (Cat5e, Cat 6). It may be shielded or
unshielded.
All field wires must be UL Listed and meet NEC 725/800 codes suitable for their installed environment. For
example: CL2 or CM rated. Plenum rating is required if routed through plenums.
Field wire lengths should be kept below 300’ but Constant Current drivers can easily operate over 1000’ and
automatically compensate for varying wire lengths.
PDM Power Input wires should be limited to 15’ to avoid requiring a larger AWG wire.
Confirm the PDM Power Input Wires and Battery to Charger wires have sufficient Amperage
carrying capacity.
Each PDM Power Input requires #12 AWG THHN wire. Up to 6 PDMs can share a #4 AWG wire.
To reduce the risk of fire, connect only to a circuit provided with a maximum branch-circuit overcurrent
protection rating not to exceed the PDM current rating of 15A each, and in accordance with the National
Electrical Code, ANSI/NFPA 70.
3.2.2

LCbus™ Wire
LCbus™ is 16 AWG 2 conductor wire and 2 UTP 24AGW wire pairs in a single jacket. The 16AWG wires allows
up to 4A (refer to UL Listed Rating for the wire). The PDM Ports do not support this power level but signal
Amplifiers can be used to repeat Switched Voltage power from L-SV1 regulators. This is effective for powering
large LED strip lights and multi-bulb fixtures such as chandeliers.
Proper fusing and protection must be used on the wires leaving the Amplifiers to avoid exceeding the wire
current capacity. Terminations at the fixture must meet the current carrying requirements. Consult your local
AHJ for requirements when using this configuration.

2. Install Channel Selection Jumpers as per system plan.
3. Install SwitchPuck modules and all LED driver modules.
4. Confirm all lights are ON.
5. Install L-PDM-PS Modules.
6. Configure SwitchPuck Modes and IDs.
7. Test grouping of Lights and Switching/Dimming.
8. Configure advanced SwitchPuck parameters.
4.3.1
Turn on power to PDMs by closing breakers to each PDM.
Confirm polarity of power into the PDM and that voltage is between 11.0-13.8VDC.
4.3.2
Install Channel Selection Jumpers as per system plan.
Channels group SwitchPuck command signals to 1-96 LED driver modules.
SwitchPucks may not share a channel. Each SwitchPuck must be on its own unique channel.
Channels can be expanded to the next PDM using a Channel jumper cable. Each group of PDMs connected by
Channel jumper cables can support 16 SwitchPucks, one for each channel.
4.3.3
Install SwitchPuck modules and all LED driver modules
SwitchPucks read inputs from switches connected to the C & S pins of SIBs in the field. SIBs are connected to
the far end of Cat5 wires connected to the PDM Ports.
0000000 rev 0.1

LibRE System Installation Guide
LED driver modules turn ON by default. This allows many control and safety benefits. A SwitchPuck on the
same channel as a driver can dim and turn off a driver.
4.3.4
Confirm all lights are ON.
Without an L-PDM-PS module, the SwitchPucks are not powered. Without a powered SwitchPuck, the LED
Drivers will default to ON 100%. This removes the complexity of the switching matrix from the commissioning
process.
Confirm all lights are ON.
4.3.5
Install L-PDM-PS Modules.
Install an L-PDM-PSx module into each PDM which contains SwitchPucks. The green power indicator should
glow and the green indicator lights on SwitchPucks should be solid or blink their mode in 1-7 blinks.
4.3.6
Configure SwitchPuck Modes and IDs
Set the Mode for each SwitchPuck by tapping their Set button. Each tap of the button increments the mode
from 1-7 blinks then back to 0 (solid).

Motion sensors work in Modes 3-6, and only turn lights on (to the Restore level) when the lights are completely
OFF. When motion is no longer detected, the lights always turn OFF.
4.3.7
Configure SwitchPuck IDs
Set the unique ID of each SwitchPuck by holding the Set button for 3 seconds. Tap the ID number into the
SwitchPuck tapping the ID number of times. Wait 5 seconds to exit ID setting and the Mode pattern should
return.
One SwitchPuck in your system must be ID #1. IDs can be from 1-128.
4.3.8
Test grouping of Lights and Switching/Dimming.
See Troubleshooting section if any lights do not control as expected.
4.3.9
Configure advanced SwitchPuck parameters.
For simple on/off configurations, no adjustments are needed in the Advanced Configuration of the
SwitchPucks. Adjusting these parameters will optimize the system efficiency and produce an outstanding
customer experience.
When dimming is used, the Minimum LED ON Level parameter must match the LED light characteristics. This
ensures 0% is OFF, 1% is the lowest ON level, and 100% is the maximum light output. When the Minimum LED
ON Level is not set to the first visible output from the light, the system may indicate that the level is above
Zero, but the LED has not yet reached light-emitting levels.
The Minimum LED ON Level should be found in the Driver section of the Luminaire documentation.
