Terminal Installation
Terminal Placement
The recommended height for the terminal's platen is between 40 and 48 inches (102 - 122 cm) from the finished floor. This height conforms to the Americans with Disabilities Act (ADA) standards (40 inches is recommended for ADA standards). All terminals within a site should be placed at the same height.
The terminal should be out of the path of pedestrian and vehicular traffic.
40” - 48” (102 - 122 cm)
Make sure that the terminal is not exposed to excessive airborne dust, direct sunlight, water or chemicals.

GT-400 Terminal User’s Guide
Removing the Terminal from the Box
-
1 Remove any accessories from the box.
-
2 Remove the packing materials from the
top of the terminal.
-
3 Lift the terminal from the box. Do not touch the underside of the terminal face.
GT-400 Terminal User’s Guide Terminal Installation: Wall Preparation
These directions and provided hardware are for installation on a hollow wall only. For installation on a solid wall, other means should be used.
1 Measure and mark a point 49 inches (124.5 cm) from the surface of the finished floor.
This point is used by the leveling hole where the top-center point of the terminal should be mounted.
At 49 inches, the unit’s platen will be 40 inches from the floor.

2 Drive a small nail into the wall at the mark.
For a solid wall, pre-drill a 1/8” hole. Insert nail into the hole.

-
3 Hang the wall plate from the leveling hole located near the top of the wall plate.
-
4 Use a bubble level to ensure that the wall plate is level.
5 Mark the locations of the two upper mounting holes and the two lower mounting holes.
For a concealed wiring connection through the wall, mark the rear cable entry hole on the wall plate.

Terminal Installation: Wall Preparation
-
6 Remove the wall plate and nail.
-
7 Drill upper and lower mounting holes.
For a concealed wiring connection, drill a 1⁄2” hole in the center of the outlined rear cable entry hole.
Additional holes may be drilled to enlarge hole for concealed wiring connection if necessary.
For a surface conduit wiring connection, ensure the conduit is routed securely to the desired conduit entry point.
-
8 Clear all dust and debris away from the terminal mounting location.

Attaching the Wall Plate
These directions and provided hardware are for installation on a hollow wall only. For installation on a solid wall, other means should be used.
1 Pull all wires through holes in wall (if necessary) and make sure wires are clear of wall plate.
2 Install the four auger-style fasteners that have been provided into the mounting hole locations. Then use the four provided screws to attach the plate to the wall.

Hang Terminal and Run Wires
1 If the side covers are attached to the terminal, they must be removed before hanging the terminal on the wall plate. See “Removing/Installing Side Covers” on page 22 for more information.
2 Slide slots in terminal over hooks on wall plate. Allow terminal to rest against the wall while performing the following steps.

3 There are several options for running the wiring to the terminal.
-
a Run wiring through hole in wall plate.
-
b Run wiring through slot in terminal.
-
c Run wiring through battery cover
(material removal required).
If using option c, locate indentation in battery cover, drill 1⁄4" hole in battery cover indentation and use utility knife to remove excess material.
Remove shaded material if using option c.
4 Tuck wires under tabs on terminal to minimize risk of crimping wires.
Tabs
5 Follow all local electrical codes when routing wire and making the terminal connections.
For concealed wiring, pull the terminal wiring through the 1⁄2” cable entry hole.
Ensure there is at least twelve inches of extra cable beyond what is needed to make the required connections to the back board.
For conduit wiring, pull an extra twelve inches of cable through the conduit beyond what is needed to make the required connections to the back board.
You may need to run the cable and then attach the connectors in order to fit cables through necessary holes and/or slots.
GT-400 Terminal User’s Guide Terminal Installation: Making Back Board Connections
Making Back Board Connections
Use caution when making connections to the back board to avoid damage. Be aware of possible damage due to electrostatic discharge (ESD). ESD is of particular concern when working on carpeted surfaces and in dry environments. Use a ground strap to minimize ESD concerns.
DO NOT apply power until you are ready to configure the terminal!
DO NOT connect backup battery (if using) until after main power has been supplied!
-
1 Connect the earth ground. The earth ground connection is made to the ground pin on the terminal. Bundle all ground connections into one crimp lug and attach the lug to the ground pin with a 8-32 nut.
-
2 Connect the ethernet cable to the ethernet connection socket inside the terminal casing.
-
3 DO NOT apply power until you are ready to configure the terminal! Connect the P1 plug to the
twisted pair per the following: Pin 1: Ground, Pin 2: Power.
See “Important Information” on page 7 for further instructions.
-
4 If using the optional backup battery, locate the backup battery relay, but DO NOT connect backup battery until after the main power has been connected.
-
5 Make other back board connections as necessary. Use the diagram below as a reference.

Attaching the Ferrite Clip
The ferrite clip must be attached to the terminal’s power cord in order to be FCC compliant.
-
1 Make a loop in the power cord
approximately six (6) inches from the power supply.
The loop will keep the clip from sliding on the power cord.
-
2 Clamp the ferrite clip over the loop. Make sure the tabs fully engage.
