Use and Care Manual

power source is fully isolated from ground and power
mains. If the transmitter is not isolated, the transmitter is
not protected from connection to energized (live) power
lines. This could cause electrical shock and damage the
transmitter. Do not use a non-isolated power supply
with the transmitter.
If using the transmitter with a 12V DC adapter from a ve-
hicle power jack while connected to a power line, the
vehicle is connected to the power line. If that power line is
energized (live), the vehicle now is at the line voltage, and
if the vehicle is grounded, could cause electrical shock or
property damage to both the transmitter and vehicle.
Pre-Operation Inspection
WARNING
Before each use, inspect your transmitter and cor-
rect any problems to reduce the risk of serious injury
from electric shock and other causes and prevent
transmitter damage.
1. Make sure that the transmitter is unplugged and in-
spect the cords and plug for damage or modification.
2. Clean any oil, grease or dirt from equipment handles
and controls. This aids inspection.
3. Inspect the transmitter for any broken, worn, missing,
mis-aligned or binding parts or any other condition
which may prevent safe and normal operation.
4. Check that the warning label is present, firmly at-
tached and readable.
5. If any issues are found during the inspection, do not
use the transmitter until it has been properly serviced.
6. Inspect any other equipment being used per its in-
structions to make sure it is in good usable condition.

Set-Up and Operation
WARNING
Always wear eye protection to protect your eyes
against dirt and other foreign objects.
Set up and operate the transmitter and work area
according to these procedures to reduce the risk of
injury from electric shock, and other causes, and
prevent transmitter damage.
1. Check for an appropriate work area as indicated in the
General Safety Section page 2.
2. Inspect the line to have a signal applied to it. The line
must be metal. If the line is not metallic, it will not be
able to be located with this equipment.
When using the transmitter on insulated conductors,
the target conductor should be grounded at each
end. Otherwise, the signal may not be strong enough
to locate.
The transmitter is not designed to provide high volt-
age isolation and protection. Do not use where a
danger of high voltage contact is present.
3. Determine the correct equipment for the application.
Using incorrect equipment for an application can
cause injury or damage the equipment.
• Equipment for other applications can be found by
consulting the Ridge Tool Catalog, online at
www.RIDGID.com or www.RIDGID.eu.
4. Make sure all equipment has been properly inspected.
5. The ST-510 line transmitter can apply an active trac-
ing signal to a conductor in three ways:
• Direct Connect – The transmitter’s leads are con-
nected directly to the target conductor and a suit-
able ground. This method is most commonly used
when the target utility is accessible. Direct con-
nect should not be used for energized (live) con-
ductors.
• Inductive Clamp (optional accessory) – the jaws of
the inductive clamp encircle the target conductor; if
the conductor is insulated, there is no metal to
metal contact. This method is commonly used
when the target utility is accessible but direct con-
nect is not possible on an insulated cable for ex-
ample. (See Page 9)
