MPE DP SERIES II, Operating And Service Manual

Page: 5 / 145

SAFETY NOTICE
Before applying power to the system, verify that the unit is configured properly for the user’s
particular application.
CE recognition of DP Series power supplies is based on rack mounted applications only. Use of
these power supplies outside of a rack mount equipment enclosure will expose the user to high
voltage and/or high current sources. Extreme caution must be used under these circumstances.
Two or more DP Series power supplies may be connected in series. For models rated 1000 V or
less and regardless of the number of units or the voltage ratings of the series connected power
supplies, the voltage potential from any output terminal to chassis ground should not exceed
1000 Vdc. For models rated greater that 1000 V and regardless of the number of units or the
voltage ratings of the series connected power supplies, the voltage potential from any output
terminal to chassis ground should not exceed 4000 Vdc.
Installation and service must be performed only by properly trained and qualified personnel who
are aware of dealing with electrical hazards. Ensure that the ac power line ground is properly
connected to the power supply chassis. Furthermore, other power grounds, including those
connected to application maintenance equipment, must be grounded for both personnel and
equipment safety.
Always ensure that facility ac input power is de-energized prior to connecting or disconnecting
the input and output power cables.
Caution: 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
cabinet. Depending on the user’s application, high voltages hazardous to human safety may be
generated normally on the output terminals. Ensure that the output power cables are properly
labeled as to the safety hazards and that any inadvertent contact with hazardous voltages is
eliminated.
This power supply is designed to be permanently connected to the power source requiring a
readily accessible disconnect device incorporated in the fixed wiring.
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.
