MODERN BURNER UNIT (MBU)
OPERATION UNDER USUAL CONDITIONS
CONNECTING CABLES TO THE MBU PRIOR TO OPERATION
Depending on the field feeding system in use, ensure that either 110 V AC commercial or generator
power is available and properly connected to the power converter, or a vehicle supplying 28 V DC power
through the NATO adapter is properly connected to a 24V DC cable extension/ branch cable, or the
battery pack. Alternatively, a fully charged battery pack may be used to start and operate up to three
MBU's for 2 to 3 hours, depending an ambient temperatures as described in WP 0005.
HIGH VOLTAGE is used in the operation of this equipment. DEATH ON CONTACT may result
if personnel fail to observe safety precautions
Never work on electrical equipment unless there is at least one other person nearby who is
familiar with the operation and hazards of the equipment. That person should also be
competent in giving first aid. Ask maintenance personnel about any hazardous features of the
MBU prior to doing any maintenance.
Whenever possible, external power must be shut off before performing any maintenance.
Be careful not to contact high-voltage connections when removing, installing or operating this
Whenever possible, keep one hand away from the equipment to reduce the hazard of current
flowing through vital organs of the body. Voltages as low as 50 volts may cause death.
For artificial respiration, refer to FM 21-11.
Do not stand in water while handling live power cords or electrical shock may result. Position
all power cables so that they are out of the way during operation and are not lying in water.
