General
The Redwood® Engine 3 Model 4834 powers and communicates with Redwood gateways, sensors, and wall
switches to provide intelligent lighting control and building intelligence. The engine provides a sophisticated level of
control w h i c h significantly reduces energy consumption. Multiple engines can be linked together to power and
control hundreds or thousands of fixtures.
The engine provides communications and control for all types of lighting including LED, fluorescent, CFL and HID.
In the case of LED lighting, the engine also provides centralized AC to DC power conversion. It takes high voltage
200–250 VAC or 277 VAC input power, converts it to low-voltage DC, and distributes the power to all fixtures via
Redwood LED sensors and gateways using Class 2, low-voltage cabling. The engine can be located on a rack or
wall mounted in an electrical or telecom closet.

Important Notes and Recommendations
For installations in Canada, no un-insulated live parts in the output from the
Redwood
engine shall be
readily accessible, as defined by the Canadian Electrical Code (CES). Accessibility shall be determined
using the risk of shock accessibility criteria such as use of the finger probe from the CSA standard(s)
cited for the category associated with the c-UL Mark.
Access to such parts should also be considered when removing panels that do not require the use of
tools when removed. Insulated parts, such as wire or cabling with outer insulation or jacket that are
certified and carry a sufficient voltage rating (>60V) are permitted to be accessible to contact.
If a fixture requires more than one channel for power, use additional wiring (see each fixture’s
specification for requirements). Note that all additional channels for a 2- or 3-channel fixture must be
connected to the same engine. Wiring for an individual fixture cannot be spread across multiple engines.
It is recommended that the fixtures in a single space be interleaved across engines. This provides
another level of redundancy — in the event of an electrical failure affecting an engine, only a portion of
the lights in a room would turn off.
18 AWG (1mm) cable installations will be wired as with category cable, except that each 18AWG cable
pair will be terminated with a Redwood RJ45-18AWG terminator. These terminators will allow the
18AWG pair to be connected to the RJ45 jack with no other modifications required. Multi-pair 18AWG
can be used with multiple Redwood RJ45-18AWG terminators attached.
The Redwood engine, director, sensors, gateways and wall switches are designed for commercial use
only and are not for residential use.

Preparation
1. Determine location for all fixtures and Redwood dimmers.
2. Determine location for all Redwood engines. The engine is a 1.5U rack mountable system and can be
installed in a standard server rack using supplied rack-mounting L brackets, or to the wall with a Redwood
wall mount kit.
3. Run low-voltage cable from engine location to each fixture location.
4. Run low-voltage cable from the engine location to each Redwood dimmer location.
5. Options for connector preparation:
If using the RJ45 connector, it can be wired as T568A (straight through) or T568B (crossover).
If using 18 AWG (1mm) wiring to connect to the engine, use a Redwood RJ45 terminator on the 18
AWG wire.
6. Install third-party light fixtures according to vendor’s installation instructions.
Installation
Rack Mount Instructions
1. Attach the two rack mount brackets to
each side of the engine using 3
screws provided on each side as
shown.
2. With power disconnected, install
engine in a standard server rack,
using mounting brackets (included).
Ensure that air vents are not blocked
and that the conditions support the
ambient operation temperature of
32°F to 122°F (0°C to 50°C).
3. Connect the cables.
