Safety Precautions for Installation

Warning

The wall mount is designed specifically for mounting a projector to a wall. If anything other than a projector is mounted, the weight may result in damage.

If the wall mount falls, it could cause personal injury or property damage.

The installation work (wall mounting and attachment of the interactive module to the projector) should be performed by specialists who have technical knowledge and ability. Incomplete or incorrect installation could cause the wall mount, projector, or interactive module to fall and cause personal injury or property damage.

Follow the instructions in this guide when installing the wall mount and interactive module.

If the instructions are not followed, the wall mount or interactive module may fall, resulting in personal injury or property damage.

Handle the power cord and USB cable carefully.

Incorrect handling may cause fire or electric shock. Observe the following precautions when handling:

•Do not handle the power plug or USB cable with wet hands.

•Do not use a power cord or USB cable that is damaged or modified.

•Do not pull the power cord or USB cable with too much force when routing them through the wall mount.

Do not install the wall mount in a place where it might be subjected to vibration or shock.

Vibration or shock could cause damage to the projector or mounting surface. It could also cause the wall mount or projector to fall and cause personal injury or property damage.

Install the wall mount so that it can sufficiently support the weight of the projector and wall mount, and resist any horizontal vibration. Use M8 nuts and bolts.

Nuts and bolts smaller than M8 could cause the wall mount to fall. Epson accepts no responsibility for any damage or injury caused by lack of wall strength or inadequate installation.

	Warning
	The installation work should be performed by at least two qualified service personnel. If you need to	English
	loosen any screws during installation, be careful not to drop the wall mount.
	If the wall mount or projector falls, it could cause personal injury or property damage.
	When you mount the projector on the wall with the wall mount, the wall requires enough strength to hold
	the projector, the interactive module, and the wall mount.
	This wall mount should be installed on a concrete wall. Confirm the weight of the projector, the interactive
	module, and the wall mount before installation, and maintain the strength of the wall. If the wall is not
	strong enough, reinforce the wall before installation.

Inspect the wall mount on a regular basis to ensure there are no broken parts or loose screws.

If there are any broken parts, stop using the wall mount immediately. If the wall mount or projector falls, it could cause personal injury or property damage.

Never modify the wall mount.

Never open the interactive module cover, except as specifically explained in this guide. Never attempt to disassemble or modify the interactive module. Keep liquids and foreign objects away from the interactive module. Refer all repairs to qualified service personnel.

Electrical voltages inside the interactive module can cause severe injury. Water infiltration or deterioration and breakage of the interactive module cover may result in electric shock.

Do not hang on the wall mount or hang a heavy object on the wall mount.

If the projector or wall mount falls, it could cause personal injury or property damage.

Do not apply excessive force to the interactive module when adjusting the projector.

The interactive module may break, resulting in personal injury.

Do not use adhesives, lubricants, or oils to install or adjust the wall mount.

If you use adhesives to prevent the screws from loosening or things such as lubricants or oils on the part of the projector attached to the slide plate, the case may crack and cause the projector to fall, resulting in personal injury or property damage.

Tighten all screws firmly after adjustment.

Otherwise, the projector or wall mount may fall and cause personal injury or property damage.

Never loosen the bolts and nuts after installation.

Confirm that the screws have not become loose on a regular basis. If you find any loose screws, tighten them firmly. Otherwise, the projector or wall mount may fall and cause personal injury or property damage.

When performing wiring, make sure the cable does not come into contact with any screws or bolts.

Handling the cable incorrectly may cause fire or electric shock.

Disconnect the interactive module’s USB cable and refer all repairs to qualified service personnel under the following conditions:

•Smoke, strange odors or strange noises come from the interactive module.

•Liquid or foreign objects get inside the interactive module.

•The interactive module has been dropped or the cover has been damaged.

Continuing to use the interactive module under these conditions may result in fire or electric shock.

Caution

Do not install the wall mount in a location where the operating temperature for your projector model may be exceeded. Such an environment may damage the projector.

Install the wall mount in a place free from excessive dust and humidity to prevent the lens or optical components from becoming dirty.

Do not use excessive force when adjusting the wall mount.

The wall mount may break, resulting in personal injury.

Caution

Because the interactive module uses infrared communication, it could interfere with infrared communication from other products. If this happens, move the other product(s) out of the detection area.

Location

•Determine where you will install the wall mount and prepare the location in advance. Also, make sure there is a gap of 16 to 26 inches (410 to 660 mm) from the top of the image projected onto the white board to the ceiling. See “Positioning the Projector” on page 14 for more details.

•Do not install the projector in a location where it might be subjected to vibration or shock. Vibration or shock could cause damage to the projector or mounting surface. It could also cause the wall mount or projector to fall, resulting in serious injury or death.

•Before installing the projector, verify the power supply wiring for the installation location.

•Install the projector away from other electric devices such as fluorescent lights or air conditioners. Some kinds of fluorescent lights could interfere with the remote control of the projector.

•Install the projector away from direct sunlight and other bright light sources.

•It is recommended to keep VGA computer cable length less than 66 ft (20 meters) to reduce external noise.

	3	Connecting Devices	English
	Make sure you have the power cord, computer VGA cable, and other parts at the location where the wall
	mount is to be installed.
	Make sure you also have all necessary cables for devices, such as a document camera or microphone, that you
	will connect to the projector. This includes cables for any optional equipment that may be connected in the
	future. For details, refer to the User's Guide on the projector CD or at epson.com/support/
	brightlinkdownloads (U.S.) or epson.ca/support/brightlinkdownloads (Canada).

Be sure to consult with the school’s technical coordinator or IT director (or with the q classroom teacher) on what equipment to use and which connections they prefer

for various devices.

Connecting Computers

You can use any of the following ports to connect computers to the projector:

•Computer1 or Computer2 (VGA connections)

•HDMI

•USB TypeB (USB display, not recommended because of reduced interactive performance)

•Video (composite video)

•LAN (RJ-45)

USB connection required (in addition to other connections) for full interactivity and dual pen support

HDMI connection			VGA connections

Video connection

LAN connection

If you connect VGA cables to both the Computer1 and Computer2 ports, make sure you label the cables. The teacher or other user needs to know which port is being used so that the correct source for full interactivity can be selected in the Easy Interactive Function menu screen.

For computer interactive pen support (using Easy Interactive Tools or other 3rd party annotation software), you need to connect a USB cable from the computer to the projector.

Connecting Through a Network

If both the projector and computer are connected to the same network by an Ethernet® cable, users can project through the network. You must install the EasyMP® Network Projection software on the computer. This software is available on the Epson Projector Software CD that came with the projector or at epson.com/ support/brightlinkdownloads (U.S.) or epson.ca/support/brightlinkdownloads (Canada).

For full computer interactivity (using Easy Interactive Tools software), you also need to connect a USB cable from the computer to the projector and select LAN as the source (see the User’s Guide for more information on selecting the source for interactivity).

10

	If your network includes a wireless router, users can connect to the projector wirelessly from computers (using
	EasyMP Network Projection software). A USB cable must still be connected from the computer to the projector
	for annotating from a computer interactive application. Users can also connect wirelessly from an iPad,
	iPhone, or iPod touch using the optional Epson iProjection™ app. When the projector is connected to these	English
	devices, only the built-in toolbar is available (single pen support).

Wireless router or access point

Wireless network connection with interactivity using the built-in toolbar

If the projector is not connected to a network (or the network does not include a wireless router), you can purchase the optional wireless LAN module for the projector. This will allow wireless projection directly from a computer to the projector and use of the built-in interactive toolbar.

You can purchase the optional wireless LAN module (part number V12H418P12) from an Epson authorized reseller. To find the nearest reseller, call 800-GO-EPSON (800-463-7766). Or you can purchase online at www.epsonstore.com (U.S. sales) or www.epson.ca (Canadian sales).

Connecting Document Cameras

Document cameras have several different types of ports for connecting to the projector.

For cameras that have USB ports, such as the Epson DC-11 and Epson DC-06, the best way to connect is directly to the computer’s USB port, as shown below. This will enable full interactivity and dual pen support (using Easy Interactive Tools software) on the document camera image.

To projector

Although you can connect the Epson DC-06 directly to the projector’s TypeA port using a USB cable, this will provide only limited interactivity (using the built-in interactive toolbar).

For document cameras that do not have a USB port, you can connect to the projector’s VGA (Computer2) or HDMI port. This will allow use of the projector’s built-in interactive toolbar on the camera image.

If the document camera has USB and VGA connectors, you can connect a USB cable from the camera to the computer and a VGA cable directly to the projector. This will provide two ways of connecting. The USB

11

connection can be used when the computer is on, and the VGA connection can be used when the teacher wants to work with the document camera without turning on the computer.

On the Epson DC-11, when the USB cable is connected from the camera to the computer, the VGA display port becomes disabled.

Using a Switch Box

You can use a switch box or control box to connect various video inputs to the projector. However, the primary computer should always be connected directly to the projector with a USB cable for interactivity and another cable for video output (VGA, HDMI, or Ethernet). This allows maximum interactivity and dual pen support (using Easy Interactive Tools software) for the computer. The projector’s built-in toolbar will be available for images from equipment connected through the switch box.

Connecting Video Equipment

You can connect various video devices, such as DVD players, satellite/cable systems, VCRs, or game systems.

Depending on the connectors available on the equipment, you can use any of the projector ports in the following list. The projector ports are listed in order from highest to lowest quality; if your equipment has multiple connectors, choose the one that provides the best quality image.

•HDMI

•Computer2 (with component to VGA video cable or adapter)

•S-Video

•Video (composite video)

HDMI connection			S-Video		Component to VGA
			connection		connection

Composite video connection

Connecting Audio

A variety of audio connections are available:

•You can connect a dynamic microphone to the Mic port and output the sound through the projector.

•You can also output computer audio. If you connected the computer using a VGA cable, you need to connect an optional 3.5 mm stereo mini-jack audio cable for sound. If you are using more than one audio connection, label the cables Audio1 or Audio2.

•If you connected the computer using an HDMI or Ethernet cable, you can output both video and audio through the cable.

•To enhance the sound from your presentation, you can connect the projector to external speakers with built-in amplifiers. The volume can be controlled using the projector’s remote control.

12

	If you want to output audio from the external speakers (or use the microphone) when the projector is turned
	off, you need to adjust the Standby Setup settings in the projector’s Extended menu. In Standby mode, you
	can output only Computer1 or Computer2 audio or composite audio (red and white RCA connectors).			English

4 Positioning the Projector

BrightLink 425Wi/435Wi/436Wi and PowerLite 425W/435W can project up to 113 inches diagonally for a WXGA image or 100 inches diagonally for an XGA image. BrightLink 421i/430i and PowerLite 420/430 can project up to 106 inches diagonally for an XGA image. You can project onto a pre-installed whiteboard or directly onto a plain wall. The height of the included wall mount determines how high the image appears on the wall or whiteboard. The distance of the projector from the wall (once it is mounted on the adjustable arm of the wall mount) also affects image size and position.

If you are planning to project on a whiteboard, the image may not fill the entire board, depending on the aspect ratio. If you match the image height to the board’s height, gaps may appear on the sides of the board.

Refer to the tables on the following pages and install the mount and projector to project images at the appropriate size. The values are only a guide. The recommended projection distance is 27.6 to 46.9 inches (70 to 119 cm).
