How to Handle the Crate When Unpacking

Read these before you touch the shipment — improper handling can damage the LED modules.

Tip #1

Always keep the crate upright. Avoid laying the crate flat on any of the sides.

Tip #2

Take care when unpacking the sign and avoid placing the weight of the sign on the LED Modules.

Understanding Cabinet Section Types

Before assembling, inspect the edges of each cabinet section. There are three configurations — understanding them helps you orient the sign correctly, especially for multi-row signs.

Open tunnel with rubber seal

Center edge. Ensure the rubber seal is in every slot before connecting M8 bolts.

Open tunnel with open-center metal gasket

Center edge — preinstalled. Used where sections meet vertically (multi-row bottom of top row).

Closed tunnel with solid metal gasket

Outside edges only. Sections with closed tunnels on top go in the top row.

For multi-row signs: sections with closed tunnels on top go in the top row. Sections with an open tunnel on top go in the bottom row.

Step-by-Step Assembly Instructions

Align the LED Sign Sections

After unpacking your X Series LED Sign, arrange your sign cabinets in sequence (A1, A2, A3…) so that a clear hole aligns with the threaded hole. For multi-row signs, start with the bottom row first.

Insert the M8 Bolts

Insert the bolt through the clear hole and screw it into the threaded hole to hold the signs in position. Each cabinet has two holes on the side. You need two M8 bolts per cable tunnel — for example, three cable tunnels = six M8 bolts.

Fasten the Bolts

Use the provided socket to fasten the upper and lower bolts on the side of each cabinet. Pay close attention to the front of the sign to ensure the LED bulbs are aligned as best as possible between sections.

Attach the X Clip

Place the X Clip in the center of every four cabinets and screw in the M10 bolts to hold the clip in position. There will be an X-Bracket at the intersection of every four modular cabinets.

Install the Mounting Brackets

Position the brackets on the back of the sign and use the provided bolts to secure the brackets to the sign. Connect brackets as needed for your specific installation method.

Lock Sign Sections Together

Connect multiple sections to assemble the required dimensions. For larger signs with stacked rows, install additional M8 bolts where cable tunnels on the top of the bottom row and the bottom of the top row intersect (two bolts per cable tunnel). Verify a silicone seal is on top of the bottom row and an open-center metal gasket is on the bottom of the top row.

Complete Assembly

Your assembled sign should resemble the illustration. After connecting all sections, install the supporting X-Brackets at each intersection of four modular cabinets.
