Electrical Installation

Only a qualified individual should terminate power and signal cable within this
Daktronics sign
.

The Daktronics engineering staff must approve any changes made to the sign. Before altering
the sign, submit detailed drawings for the proposed modifications to the Daktronics
engineering staff for evaluation and approval, or the warranty will be rendered null and void.

3.1 Common Connectors in the Sign

The power and signal connections in the signs use many different types of
connectors. Take special care when disengaging any connector so as not to damage
the connector, the cable or the circuit board.

When pulling a connector plug from a jack, do not pull on the wire or cable; pull on
the jack itself. Pulling on the wires may damage the cable and connector.

The following information presents some common connectors encountered during
sign installation and maintenance:

1. Ribbon Cable Connectors:

Figure 10 on the right illustrates a typical ribbon
connector. To disconnect the ribbon cable, push the plastic
clips on the sides of the jack to unlock and remove the
cable.

Cable Connector


Before replacing a ribbon cable connector, spray it with
DeoxIT

contact cleaner to remove any foreign matter that

may cause signal problems. In addition, apply a generous
amount of CaiLube

protector paste to the plug before

inserting it into the jack. This paste will protect both the
plug and the jack from corrosion.

2. Termination

Blocks:

Termination blocks are usually used to connect internal
power and signal wires to wires of the same type coming
into the sign from an external source. Power wires need to
have one-half inch of insulation stripped from the end of
the wire prior to termination. Tighten all screws firmly to
ensure a good electrical connection. Refer to Figure 11 on
the right.
