Wiring Applications
The L35 Series is able to receive up to 120 programmable inputs, each requiring
home-runs to the L35 Series. To avoid multiple home-runs of standard switches
TRIATEK Lighting recommends installing DDN Series Digital Switches. Refer to the
Digital Override Switches data sheet on the website. Instructions for installing the
DDN Module can be found under “Upgrading the L35 Series” in this manual.
The L35 Series can be installed as a stand-alone lighting control system, or it can
be upgraded to integrate with TRIATEK Lighting’s BASnet® LightView™ for web-
based control or a Building Automation System (BAS). Once the L35 Series system
is connected to BASnet LightView or a BAS, multiple L35 Series panels can be
linked together for greater control. These examples are illustrated below.

Mounting the L35 Series Enclosure
1. Knockout Holes for high and low voltage conduit connections. Figure 2
illustrates areas in the L35 Series enclosure where conduit holes for high and low
voltage wiring can be made.
a. Remove the interior. If the panel was shipped with electronics installed, remove
the interior with electronics until all holes for conduit are punched and all metal
shavings are removed. Metal shavings from drilling could lodge in the electronic
components and cause damage.
The interior is held to the enclosure by four flange nuts. See Figure 3 below. Re-
move the interior and place it away from any work area before drilling holes for
conduit.
2. Mount the enclosure with anchors and screws according to Figure 3.
Figure 3 illustrates the location of the panel mounting holes. The top two mount-
ing holes of the panel enclosure are keyhole shaped so you can slide the unit over
mounting screws, avoiding the need to hold the unit while trying to secure the
mounting screws. Use wall anchors capable of supporting more than 80 pounds
(60 relay unit).

If flush mounting, secure the enclosure between the wall studs. Be sure to allow
for the thickness of the drywall and 7/8” for the overhang of the cover so that the
panel’s cover will mount flush on the finished wall and away from adjacent panels.
Connecting the Power Supply
The L35 Series can be powered by either 120 or 277VAC. A fuse and dual primary
transformer are utilized to offer maximum flexibility during installation. This factory
mounted transformer powers the L35 Series controller and associated low voltage
coils on the contactors (relays).
1. If connected, remove the power harness from the L35 Series controller. See
Figure 4 for location of the harness on the controller. Remove the harness by lifting
on the terminal block of the harness.
2. Connect main power to the transformer and fuse assembly. Locate the
Common (white) wire and the hot (black) wire for connection to main power. Each of
these wires contains a “quick connect” connector. To connect a power wire to this
connector, pinch the end of the connector to open it for wire insertion. Release the
end of the connector with the wire inserted to allow the connector to hold. Figure 4
shows the connectors on the white and black wires.
3. Locate wire with correct voltage and connect to fuse. Refer to Figure 5.
Power is connected by choosing the proper voltage wire stemming from the trans-
former and connecting that wire to the fuse holder. Each wire is labeled either 120V
or 277V. The 120V wire should be black, and the 277V wire should be brown. If
this is not the case contact the factory immediately. Each wire is terminated with a
spade connector that inserts over a contact on the fuse holder.

Connecting Branch Circuit Wires
The L35 Series panel is equipped with contactors capable of switching up to 20
amperes at 277 VAC (Canadian versions, 347VAC). Each contactor can be easily
assigned to any of the unit’s zones. Refer to the “LP Controller User’s Guide” on
our website. Figures 7 and 8 are typical wiring diagrams. Be sure not to exceed
20 amperes per contactor. If the high voltage wiring requires both 120V and 277V,
TRIATEK Lighting’s LDIV High Voltage Divider will be required. Contact TRIATEK
Lighting for details.
1. Pull branch circuit wires through high voltage conduit. Note: All wiring should
be in accordance with local regulations and the National Electric Code. Control sig-
nal wiring to the low voltage side of the unit should not be run in the same conduit
as line voltage wiring or other conductors that supply highly inductive loads such as
generators, motors, or high voltage circuits located on the high voltage side of the
unit.
If 120V and 277V branch wires must be connected to relays on the same side of
the panel do not run these wire through the same conduit. See Figure 2 for high
(load) and low (24V) voltage areas of the panel.
2. Install each branch circuit in one contactor as shown in Figure 6. Each
branch circuit can be installed in a contactor as shown in Figure 6 below.

Connecting Switch Inputs
The L35 Series Controller comes standard with 24 programmable switch input ca-
pacity. The 24 termination points are divided into three sections of eight, with each
section containing one ground point ( all three grounds are common ). All points are
numbered, and ground points are labeled “G”. Do not apply AC voltage to any of
the terminals. Switch inputs location and labeling on the L35 Series Controller are
shown below.
The inputs can be momentary on, momentary off, momentary on/off, maintained,
linked, or state change. Each section has an accompanying jumper that sets
whether its associated eight inputs will be up to 24 VDC or dry (0 VDC). Table 1 lists
the switch inputs and associated jumpers.

Each jumper set has 3 pins, one of which is labeled “N”. The “N” jumper is for set-
ting the switch inputs for dry contact. The “up to 24” pin of the jumper pin is not
labeled. Figure 10 shows how to place jumpers properly.
The jumper must be set before wiring. If one switch input is dry, the entire section
of eight switch inputs must also be dry contacts, and the associated jumper must
be in the “dry” position. If one switch input is externally powered up to 24 VDC, the
entire section of eight switch inputs must also be up to 24 VDC, and the associated
jumper must be in the “up to 24” position.
1. Remove power to the controller. Refer to Figure 4. Remove the yellow/blue
power harness by lifting on its terminator block.
2. Set jumpers. See explanations and Figures 9-10 and Table 1 above.
3. Connect the switches to the controller. Connect one end of the switch or
contact to terminal “G” and the other to terminal “1-24”. Momentary switches which
have both an ON and Off contact will require two switch inputs on the controller.
See Figure 11 for sample wiring diagrams for each input type. Switch input terminal
blocks are screw type. Land wires by unscrewing, inserting the stripped wire, and
tightening the screw.
3. Reconnect power to the controller.
CAUTION: Before handling any components on the circuit board, the
installer should be grounded to prevent damaging the board.

Lighting recommends installing the ribbon cables by running them underneath the
electronic boards between the plate and the board. This keeps ribbon cables out
of the way when installing switch wires. Figure 23 shows ribbon cable connection
locations at the LEXP modules and at the LMB. Take care not to drive the mounting
plate screws through the ribbon cable.
When running the ribbon cable to the LMB, run the cable down behind the hinged
plate the LMB is mounted to. Then run the cable over the front of the plate and un-
der the LMB. Bring it out from in between the LMB and its plate and connect it into
its socket labeled, “EXPANSION INPUTS”.
The LEXP board does not need a separate power source. It receives power through
the ribbon cable.

Connecting Expansion Board Switch Inputs
The expansion module contains 32 programmable switch inputs that are controlled
in sections of eight as with the 24 switch inputs of the controller. Each section of
eight switch inputs is set to either dry contact or up to 24 VDC with jumpers as well.
On the expansion module the jumpers are labeled by the numbered range of switch
inputs they control instead of by jumper number. For example, the jumper that sets
switch inputs 1-8 is labeled “1-8.” Dry and up to 24 jumper positions are labeled
“N” and “R”. Refer to Figure 24a for jumper details. The illustration below (Figure 25)
indicates jumper location and labeling.
Figure 25 above also shows one more set of jumpers: jumpers labeled J5 (with
positions A and B) and J6 (positions C and D). The L35 Series can accept up to
120 programmable switch inputs, comprised of 24 from the controller and 3 X 32
from expansion boards. If more than one expansion card is used for additional
switch inputs, the controller must be able to distinguish expansion boards. There-
fore, A, B, C, D refer to board identification settings. If the expansion module will
interface with inputs 25-56, the jumper should be set to A. The board that inter-
faces 57-88 should be set to B, and so on. The installer should note that there is
not a D module. The maximum number of expansion boards possible is three. Do
not attempt to install a fourth expansion board and set its jumper to D; the L35
Series controller will not recognize the inputs. Use Figure 24b to properly set the
identification jumper.
1. Remove power to the controller. Remove the yellow/blue power harness by
lifting on its terminator block.
2. Set jumpers. See explanations and Figures 24 and 25 above.
3. Connect the switches to the expansion board. Refer to Step 3 instructions
under “Connecting Switch Inputs” in this manual.
3. Reconnect power to the controller.
CAUTION: Before handling any components on the circuit board, the
installer should be grounded.

Installing the DDN Module
The DDN Module for the L35 Series (Cat# DDN-L35) mounts to the back side the
hinged plate upon which the LMB is mounted. See Figure 29 for its location. The
DDN module communicates with the LMB through a ribbon cable, and it receives
its power from the LMB through a 2-wire connection. The DDN Module comes with
four mounting screws, one ribbon cable, and two power wires. See Figure 26 for
displayed parts.
1. Disconnect power. Refer to Figure 4 on page 7 for power connection location.
Remove power by lifting the terminal block from the power terminals.
2. Remove LMB. Remove the LMB by removing the six screws shown in Figure 27.
3. Open hinged backplate to locate the mounting position for the DDN. Open
the hinged backplate by unscrewing the two thumb screws. They are located just
above the LMB.
4. Mount the DDN on the four mounting standoffs of the backplate. See Figure
28.
5. Connect ribbon cable to DDN. Close the hinged backplate to view the DDN
socket for the ribbon cable through square opening of the backplate. Connect the
cable, and then fold the ribbon cable to fit between LMB and its plate as shown in
Figure 30.

6. Remount the LMB.
7. Plug the ribbon cable into its socket on the LMB. Figure 31 demonstrates the
location and labeling of this socket. The socket is labeled ‘LCD DISPLAY’ or ‘DDN’.
8. Connect the power wires for the DDN to the LMB. Figure 32 gives the loca-
tion for power source for the DDN module. The power terminal on the LMB and
DDN has “P” and “G” labels for hot and ground connections respectively. Connect
the black wire to “G” on the LMB and the red wire to “P” on the LMB.
9. Run both wires together between the LMB and the hinged backplate and
then pull the wires between the two bottom screws of the LMB. Example run
is shown in Figure 32. If power is run to the DDN across the side of the backplate,
when the backplate is closed, the wires will get pinched.
10. Open the hinged plate and pull the wires to the DDN module. Terminate the
wires at the provided power terminal block. See Figure 33.
11. Reconnect power to the LMB. Refer to Figure 4 on page 7 for power termina-
tion location. Figure 32 also gives the location.
