OHM™ LIGHT USER MANUAL

Warnings and Cautions

Read, keep, and heed all warnings and cautions.

This product is protected by Patents and pending Patent applications.

SYMBOL MEANING

Risk of Electric shock / Risk of Fire

Do not open. To reduce the risk of electric shock, do not remove cover (or back). No user-
serviceable parts inside. Refer servicing to qualified service personnel.

Burning Injuries

Be aware of high case temperatures of 60-90°C while and after use of OHM. Don't touch the 
metal cases, frames, LEDs to avoid burning injuries.

Flammable Materials

Keep flammable materials away from the installation (such as curtains). A lot of energy is 
transferred into heat. The installation should be such that the amount of air flow required for 
safe operation of the equipment is not compromised. Proper ventilation must be provided.

ESD and LED's

LED components used in OHM are ESD (Electro-Static Discharge) sensitive. To prevent the 
possibility of destroying LED components do not touch either in operation or while switched 
off. DO NOT remove the clear protective cover in front of the LEDs or optics.

Light Output

Due to high light-output intensity do not look directly into the bare LED. Use diffusers when 
exposing the light to human eyes.

Disconnect Device

When the appliance inlets of the individual OHMs are not accessible, the socket outlets 
supplying the rack shall be installed near the equipment and be easily accessible, or a readily 
accessible general disconnect device shall be incorporated in the fixed wiring. Disconnect 
device should state 3mm separation in both poles and should include reference to national 
wiring rules.

This equipment MUST be earthed

In order to protect against risk of electric shock, the installation should be properly grounded. 
Defeating the purpose of the grounding type plug will expose you to the risk of electric shock.

Mains Cords

Use only a Neutrik PowerCon NAC3FCA Connector. The user is responsible for ensuring 
power cables are of adequate condition for each application. If the power cords are damaged, 
replace them only with new ones. Never try to repair a power cord.

Environmental: Disposal of Old Electrical & Electronic Equipment

This symbol on the product or on its packaging indicates that this product shall not be treated 
as household waste.
