Requirements for electrical installation
Notice: The following electrical installation requirements must be followed or the sign warranty will be voided. Electrical installation
must only be attempted by a qualified electrician. Electrical connection must comply with all applicable national and local
codes.
The electrical installation of signs varies greatly. The following bullet points are requirements. It is the installer’s responsibility to
ensure that the installation complies with all national and local codes.
• All power wiring must be from circuit breaker-protected lines.
• DO NOT connect the sign to a GFI-protected circuit.
• A disconnect device must be installed in the building wiring for the branch circuit(s) supplying the sign. For the power requirements
for each sign, refer to the sign rating label located on front, back and interior of the sign.
• The sign must be properly grounded according to the applicable national and local electrical codes (for example, NEC Article 250
and 600, and IEEE 1100-1999).
• All electrical conduit connections must be watertight.
• Torque terminals to a minimum of 13 in/lbs (1.5 N/m) and a maximum of 16 in/lbs (1.8 N/m).
• Use minimum 80° C copper wire only.
• DO NOT drill additional holes in the sign.
• DO NOT route power and communication wires out of the door and around the side of the sign; the wires will be damaged when
the door is closed.
• Separate conduits must be used for signal wires (for example, Ethernet) and for power wires. However, fiber optic wire may be
run in the same conduit with power wires.
Power requirements
Adequate power must be run to the sign in accordance with the “Technical Specifications” on page A-1.
• Standard configuration is 120VAC. The sign may be configured as 240VAC as a custom order.
• The sign must be run on it’s own dedicated circuit to ensure proper operation. This is particularly important when the sign is
installed in a structure containing ballasts for fluorescent lamps. They must have their own circuit. Not complying with this
requirement can lead to intermittent sign operation or malfunction.
•
Do NOT run power to the sign and the ballasts off the same circuit.
• When ballasts are used in the same vicinity of the Adaptive sign, it is recommended that they be of the electronic low
harmonic type to further reduce the risk of any interference with the sign.
• Wire gauge and breakers must be sized or verified in accordance with Adaptive’s input power specifications, the National
Electric Code, and applicable local codes. Under-sizing the wire gauge or breaker size can lead to intermittent sign
operation or malfunction .
DANGER
Hazardous voltage. Contact with high voltage will cause death or serious injury. The power switches on the circuit
breaker DO NOT turn off power to all lines in a sign. Remove power at the source.
Is it necessary to run
two
conduits to a sign?
It is not always necessary. Two conduits are only necessary when communication wire, like CAT-5 wire, is run to a sign from a computer or from
another sign. In these cases, one conduit would contain the sign’s power wires and the other conduit the communication wires.
If power and communication wires are put in the same conduit, there is a chance the communication wires might pick up electrical interference from
the power wires. For example, when a live power cord is placed next to a stereo speaker wire, the interference from this cord may cause the speaker
to hum. In the case of a sign, this same effect could disrupt messages sent to the display.
On the other hand, fiber optic cable and power wires can share the same conduit because fiber optic cable is immune to electrical interference.
