erty includingthe equipment itself.
DANGER indicatesa personalinjury hazard immediately ac-
cessible as one reads the marking.
SYMBOLS
In This Manual
This symbol indicates where applicable cau-
tionary or other informationis to be found.
As Marked on Equipment
DANGER - High voltage.
@ Protective ground (earth) terminal.
ATTENTION
- refer to manual.
Power Source
This product is intended to operate from a power module
whose power sourcewill 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 essen-
tial for safe operation.
Groundingthe Product
This product is grounded through the grounding conductor
of the power module power cord. To avoid electrical shock,
plug the mainframe power cord into a properly wired recep-
tacle beforeconnectingto the productinputor output termi-
nals. A protective ground connection by way of the
grounding conductor in the power cord is essential for safe
operation.
Danger Arising From Loss of Ground
Upon loss of the protective-groundconnection, all accessi-
ble conductive parts(includingknobs and controls that may
appear to be insulating)can render an electric: shock.
----
Use the Proper Fuse
To avoid fire hazard, use only the fuse of correct type, volt-
age ratingand current rating as specified in the partslistfor
your product.
Refer fuse replacement to qualified service personnel.
Do Not Operate in Explosive Atmosphe!res
To avoid explosion, do not operatethis product in an explo-
sive atmosphere unless it has been specifically certifiedfor
such operation.
Do Not Operate Without Covers
To avoid personal injury, do not operate this product with-
out covers or panels installed. Do not apply power to the
plug-invia a plug-in extender.
