WARNING statements identify conditions or practices
that could result in personal injury or loss of life
As Marked on Equipment
CAUTION indicates a personal injury hazard not im 
mediately accessible as one reads the marking, or a
hazard to property including the equipment itself
DANGER indicates a personal injury hazard immediately
accessible as one reads the marking
Grounding the Product
This product is grounded through the grounding conduc 
tor of the power cord To avoid electrical shock, plug the
power cord into a properly wired receptacle before
connecting to the product input or output terminals A
protective ground connection by way of the grounding
conductor in the power cord is essential for safe opera 
tion
Danger Arising From Loss of Ground
Upon loss of the protective-ground connection, all
accessible conductive parts (including knobs and con 
trols that may appear to be insulating) can render an
electric shock

DANGER — High voltage
Protective ground (earth) terminal
ATTENTION — refer to manual
Power Source
This product is intended to operate from a power source
that will not apply more than 250 volts rms between the
supply conductors or between either supply conductor
and ground A protective ground connection by way of the
grounding conductor in the power cord is essential for
safe operation
Use the Proper Fuse
To avoid fire hazard, use only the fuse of correct type,
voltage rating and current rating as specified in the parts
list for your product
Refer fuse replacement to qualified service personnel

SPECIFICATION
INTRODUCTION
Instrument Description
The TM 515 is a five-wide power module compatible
with most TM 500 plug-ins It provides unregulated ac and
de supplies and nondedicated power transistors for use by
the plug-ins This mainframe does not have a high-power
compartment but does feature forced-air cooling
Available options allow the rear i nterface to be customized
(Option 5), operation from power sources with a line
frequency of up to 400 Hz (Option 6), and specific
interconnections for specialized plug-ins (Option 7)
Performance Conditions
The values listed below are valid only when the
instrument is operated at an ambient temperature
between 0°C and +50° C
