Safety Notice
Before applying power to the system, verify that the unit is configured properly for the
user's particular application.
CE and UL recognition status of this series of power supplies is based on rack mounted
application only. Use of the power supplies outside of a rack mount enclosure will
expose the user to high voltage and/or high current sources. Extreme caution must be
used under these circumstances.
The analog control inputs (connectors J1 and J2) on the rear panel are referenced to the
negative output of the power supply. Grounding the positive output of the power supply
or biasing the output of the supply above chassis potential will cause these inputs (along
with the output of the supply) to have a potentially hazardous offset voltage. Exercise
caution under these conditions. Under no circumstances should the negative output of
the supply be more than 150 volts, positive or negative, from chassis potential.
Installation and service must be performed only by properly trained and qualified
personnel who are aware of dealing with attendant hazards. This includes simple
tasks such as fuse verification.
Ensure that the AC power line ground is connected properly to the unit input
connector or chassis. Similarly, other power ground lines including those to
application maintenance equipment must be grounded properly for both
personnel and equipment safety.
Always ensure that facility AC input power is de-energized prior to connecting or
disconnecting the input/output power cables.
Warning: Lethal voltages may be present inside the power supply even when the
AC input voltage is disconnected. Only properly trained and qualified
personnel should remove covers and access the inside of the power
supply.
During normal operation, the operator does not have access to hazardous voltages
within the chassis. However, depending on the user's application configuration, HIGH
VOLTAGES HAZARDOUS TO HUMAN SAFETY may be generated normally on the
output terminals. Ensure that the output power lines are labeled properly as to the
safety hazards and that any inadvertent contact with hazardous voltages is eliminated.
Due to filtering, the unit has high leakage current to the chassis. Therefore, it is
essential to operate this unit with a safety ground.
This unit is designed to be permanently connected to the power source and as such
must have a readily accessible disconnect device incorporated in the fixed wiring.
After the unit has been operating for some time, the metal near the rear of the unit may
be hot enough to cause injury. Let the unit cool before handling.
These operating instructions form an integral part of the equipment and must be
available to the operating personnel at all times. All the safety instructions and advice
notes are to be followed.
Neither Power Ten nor any of the subsidiary sales organizations can accept
responsibility for personal, material or consequential injury, loss or damage that results
from improper use of the equipment and accessories.
