Loosen the Locknut on Cable Coupler.
Rotate the Locknut and tighten.
Pass the Power Cord through the Canopy Rings. Adjust the length of the Power Cord and tighten it on the Canopy with Strain Reliefs.
Mount all Canopies to the Fixture with appropriate Cable length.

CANOPY-TO-SURFACE MOUNTING

Slide Power Cord through the hole on Canopy and tighten with Strain Relief. Slide Power Cord through the hole on Canopy and tighten with Strain Relief. Orient the Fixture so that the Canopy with Power Cord is aligned with supply wire access as shown in Fig. 5.
Connect wires as shown in wiring diagram. Push all wires back into the Junction Box. Be careful not to pinch wires. Mount the Cross Bar on Junction Box.
Place the Canopy on the mounting surface. Push Cable Coupler on the 1/4-20 Stud and tighten the Fixture.
Canopy and Cable without Power Cord can be mounted with a1/4 -20 Stud and hardware appropriate to mounting surface.
Push L ens and Tray Assembly into the Housing Cover. Align Keys into Key Slots and slide to the left to lock the Housing Cover into the Lens and Tray Assembly. Snap on End Caps.

WARNING: To prevent wiring damage or abrasion, do not expose wiring to edges of sharp objects.

CONTINUOUS RUN MOUNTING

Multiple fixtures can be mounted together using TOMO CONNECT (sold separately).

Note: Continuous Run Mounting is not available with LIGHTCLOUD® /LC, /LC/E, /LCB suffix.

For continuous run, remove fixture End Caps (Fig. 6). Pop out Silicone Plugs, push Fixtures together using TOMO CONNECT (ordered separately) between fixtures for quick connect installation (Fig. 7). TOMO CONNECT is provided with (2) Fixing Screws. Install Fixing Screws in Silicone Plug points. Only (1) one Fixture needs to be electrically hard wired from above (Fig. 8).
CAUTION: The maximum number of fixtures allowed to be linked together is indicated in table below (120V through 277V only).

WARNING: To prevent wiring damage or abrasion, do not expose wiring to sharp objects.

Catalog #	Maximum Number of Linked Fixtures
TOMO-2	Up to 28 fixtures
TOMO-4	Up to 14 fixtures
TOMO-8	Up to 7 fixtures

FIELD ADJUSTMENT

Follow instructions below to change the fixture Color Temperature (CCT) and Power (W) from the factory settings.
Factory Settings:
TOMO-2 18W / 4000K
TOMO-4 36W / 4000K
TOMO-8 72W / 4000K

Remove End Caps. Slide Lens Tray Assembly from Housing Cover to release Tray Assembly from Housing Cover by sliding the fixture to the right to unlock from Key Slots as shown in Fig. 3. Pre-installed Tether Cables (2) will prevent Lens and Tray Assembly from separating from Housing Cover as shown in Fig. 1.
Locate the selector switches inside the Lens & Tray Assembly as shown below for TOMO-2, TOMO-4 TOMO-8 (Fig. 9, 10, 11). Note: TOMO-8 is equipped with two (2) Color Temperature (CCT) switches and (2) two Power (W) switches.
Select a Color Temperature (CCT) and Power (W) by sliding the respective switch to the desired value.
After the switch is positioned to the desired setting, push Lens and Tray Assembly into the Housing Cover. Align Keys into Key Slots and slide to the left to lock the Housing Cover into the Lens and Tray Assembly. Snap on End Caps.

WARNING: To prevent wiring damage or abrasion, do not expose wiring to edges of sharp objects.

0-10V DIMMABLE WIRING

Universal voltage driver permits operation at 120V through 277V, 50 or 60 Hz. For 0-10V dimming, follow the wiring directions as shown in Fig. 12.

Connect the black fixture lead to the LINE supply lead.
Connect the white fixture lead to the COMMON supply lead.
Connect the GROUND wire from fixture to supply ground.
Connect the purple fixture lead to the (V+) DIM lead.
Connect the pink fixture lead to the (V-) DIM lead.
Cap the yellow fixture lead, if present. Do NOT connect.

CLEANING & MAINTENANCE

CAUTION: Be sure fixture temperature is cool enough to touch.

Do not clean or maintain while Fixture is energized.

Clean acrylic lens with non-abrasive cleaning solution.
Do not open the fixture to clean the LEDs. Do not touch the LEDs.

TROUBLESHOOTING

Check that the line voltage at the fixture is correct. Refer to wiring directions.
Is the fixture grounded properly?

Note: These instructions do not cover all details or variations in equipment nor do they provide for every possible situation during installation, operation or maintenance.

BATTERY BACKUP MODELS

WIRING

CAUTION: FOR BATTERY BACKUP FIXTURE (TOMO-4/TOMO-8) Voltage could be present in BATTERY. To prevent high voltage from being present on output leads, Inverter Connector must be open. Do not join BATTERY connector until installation is complete and AC power is supplied to the emergency driver (Fig. 13).
NOTE: Make sure that the necessary branch circuit wiring is available. An UNSWITCHED AC source of power is required. The emergency driver must be fed from the same branch circuit as the LED driver.
CAUTION: Do not use any supply voltage other than 120-277V 50/60 HZ.

Connect UNSWITCHED HOT fixture lead to HOT AC supply line.
If using an UNSWITCHED circuit, connect UNSWITCHED and SWITCHED lines together.
If using a SWITCHED circuit, connect SWITCHED HOT AC fixture lead to the external control.
For 0-10V dimming, connect DIM (+) purple lead and DIM (-) pink lead to 0-10V dimmer connections.
Connect GROUND lead from the fixture to the supply ground. Do not connect GROUND to the output leads.
All unused leads must be capped and insulated.
After installation is complete, supply AC power to the fixture and connect the BATTERY (Fig. 13).
When power is on, the fixture should be on and the Charging Indicator Light should illuminate to indicate the battery is charging.
Once the BATTERY has charged for at least one hour, a short duration test may be performed by pressing the test button.
After the battery has charged for 24 hours, a long duration test can be performed by shutting power to the fixture.

OPERATION

When AC power is applied, the charging indicator light is illuminated indicating that the BATTERY is being charged.
When power fails, the standby power automatically switches to backup mode at reduced power resulting in lower illumination. The emergency driver supplies power in standby mode for a minimum of 90 minutes.
When AC power is restored, the emergency driver automatically returns to charging mode.

MAINTENANCE

Although no routine maintenance is required to keep the emergency driver functional, it should be checked periodically to ensure that it is working. The following schedule is recommended:

Visually inspect the charging indicator light monthly. It should be illuminated.
Test the emergency operation of the fixture at 30-day intervals for a minimum of 30 seconds.
Conduct a 90-minute discharge test once a year. Fixture would operate at reduced illumination for a minimum of 90 minutes.

TROUBLESHOOTING

Is the fixture grounded properly?
If the charging indicator light does not illuminate after pressing the Test Button (Fig. 14), check if battery is connected properly.

Note: These instructions do not cover all details or variations in equipment nor do they provide for every possible situation during installation, operation or maintenance.
