SAFETY PRECAUTIONS
The following symbols in this manual signal potentially dangerous conditions to the operator or equipment.
Read this manual carefully. Know when unsafe conditions can exist. Then, take necessary steps to protect
personnel, as well as equipment.
WARNING: TEREX Amida uses this symbol throughout this manual to warn of possible fatal injury.
CAUTION: TEREX Amida uses this symbol to point out potential damage to equipment.
Lamps, fuels, electrical equipment, batteries, exhaust gases, loose fasteners, and moving parts present potential
hazards that could result in serious personal injury. Be diligent in following the procedures recommended
below. Also, observe the many additional general safety rules practiced by trained operation and maintenance
personnel in your company and industry. CAUTION: Always wear a hard hat when operating the light
tower!

Guard Against Electrical Shock
This light tower also has provisions for producing high voltage electricity (up to 480 volts) that can produce
a fatal shock to a person who accidentally places their self in the electrical circuit.
Use every precaution to avoid contact with the high voltage electric circuit.
Beware of a cut or damaged power cord. Replace immediately.
Take extra precautions when troubleshooting electrical problems:
•
When troubleshooting indicates a malfunction in the high voltage AC system, then pass the troubleshooting
task on to a qualified and trained electrician.
•
Disconnect electrical power and turn off engine before removing protective covers on high voltage enclo-
sures.
•
Understand that the electrical circuits in this light tower complete their paths back to the generator within
the equipment. The neutral conductor at the generator is bonded to the equipment frame.
•
Ground wires within the system are also bonded to the equipment frame.
•
Only use a multimeter (or voltmeter) with two well-insulated probes rated for 750 volts.
•
Keep one hand in your pocket when touching the multimeter probe to hot conductors. This will prevent
electricity from passing into one hand and out the other, a path that takes the electricity across the heart.
Always disconnect power from the circuit being measured before connecting test leads to high voltage
points.
•
Do not try to position both probes at once. Instead, clamp the common insulated alligator clip to a neutral
wire and then probe for voltages with the other probe.
•
Never clamp to a hot wire since a severe shock could be received by contact with the other probe.
•
Do not use a multimeter with leads or probes that have damaged insulation.
•
Inspect the ground cable between the generator set and the frame. If damaged, replace immediately.
•
Treat all conductors as potentially hot, especially when troubleshooting malfunctioning equipment. Jewelry
should be removed before working around live conductors.
•
Proceed through the circuitry systematically, operating only one section at a time.
•
Use tools with insulated handles when working within the reach of live conductors.
•
Maintain a good footing. If you slip, or a tool drops, do not grab for it if live conductors are within reach.
•
Concentrate on the task until the danger from high voltage is removed.
