1. GENERAL INFORMATION
1.1 Introduction
This section contains a general description of your power supply as well as its performance
specifications. Information about options and accessories are also provided.
The TPS-3025 series has been designed and tested according to EN-61010-1, Safety requirement for
Electronic Measuring Apparatus.
1.2 Safety Considerations
SAFETY PRECAUTIONS
SAFETY NOTES
The following general safety precautions must be observed during all phases of operation, service,
and repair of this instrument. Failure to comply with these precautions or with specific warnings
elsewhere in this manual violates safety standards of design, manufacture, and intended use of the
instrument. The
manufacturer assumes no liability for the customer’s failure to comply with these
requirements.
BEFORE APPLYING POWER
Verify that the power supply is set to match the available line voltage and the correct fuse is installed.
GROUND THE INSTRUMENT
This product is provided with a protective earth terminal. To minimize shock hazard, the instrument
chassis and cabinet must be connected to an electrical ground. The instrument must be connected to
the AC power supply mains through a three-conductor power cable, with the third wire firmly
connected to an electrical ground (safety ground) at the power outlet. For instruments designed to be
hard-wired to the AC power lines (supply mains), connect the protective earth terminal to a protective
conductor before any other connection is made. Any interruption of the protective (grounding)
conductor or disconnection of the protective earth terminal will cause a potential shock hazard that
could result in personal injury. If the instrument is to be energized via an external autotransformer for
voltage reduction, be certain that the autotransformer common terminal is connected to the neutral
(earthed pole) of the AC power lines (supply mains).
The RS232 (option) Ground is connected with chassis ground, and therefore the operator must take
care if the computer is also connected with other measuring devices prevent a short cut.
FUSES
Only fuses with the required rated current, voltage, and specified type (normal blow, time delay, etc.)
should be used. Do not use repaired fuses or shout circuited fuseholders. To do so could cause a
shock or fire hazard.
DO NOT OPERATE IN AN EXPLOSIVE ATMOSPHERE
Do not operate the instrument in the presence of flammable gases or fumes.
KEEP AWAY FROM LIVE CIRCUITS
Operating personnel must not remove instrument covers. Component replacement and internal
adjustments must be made by qualified service personnel. Do not replace components with power
cable connected.
