DANGER
The following maintenance and troubleshooting suggestions should
only performed by qualified electricians with working knowledge of
airfield lighting series circuit power.
Dangerous/lethal voltage may be present in the electronics enclosure.
A clear plastic box container of adequate L × W × H should be placed
over the electronics enclosure and temporarily held in place during
troubleshooting to prevent accidental human contact with live
electrical components. The box container should also be of adequate
size to install/remove a current clamp when sign power is
locked out
allowing any leads connecting to a meter to run under one of the box
container edges with it duct taped over the coverless electronic
enclosure. Note: LED strips/leads inside the sign body have less than
60 VDC present. Components inside the electronics enclosure and
power cable may have 6.6 amperes and/or 24 VAC.
