1. SAFETY
1.1
OVERVIEW
This equipment is designed to be connected to hazardous electric voltages. Ignoring the
installation precautions and warnings can result in severe personal injury or equipment
damage. The following are general guidelines that should be followed when installing,
operating and servicing the RCEM.
•
Qualified technicians who are familiar with the warnings and instructions of this manual
must perform all installation, maintenance and service.
•
Always follow all local and plant safety procedures.
•
The equipment covers should remain closed at all times during operation to ensure
safety of personnel. Only authorized personnel or technicians should be allowed to
open and service the equipment.
•
Cover #3 (PC Board Cover) may be removed if the operator needs access to the diode
waveform connectors. Use caution whenever the cover is removed.
•
Only qualified technicians should perform Service. If use of an oscilloscope becomes
necessary during operation or servicing, either the scope must be floating or
ungrounded, or differential probe(s) must be used. The equipment is isolated from the
mains via the power transformers. If a grounded scope is used, a hazardous condition
is created since current will flow through the probe to ground.
•
Replace fuses with correct type, size and value. Refer to the servicing instructions or
spare parts list for more information on replacement fuses. Do not bypass the fuses or
modify the electronics. Disconnect power to the system before replacing fuses. Failure
to follow these instructions will result in intermittent operation and premature failure and
will void the warranty.
•
The equipment is not intrinsically safe. Do not place in explosive atmospheres.
•
The Current Transducers are double insulated to protect the operator from possible
hazardous voltage potentials of the rectifier. The transducers are also protected from
heat by a protective sheath.
•
Make sure the transducer cables and interconnection cables are kept well away from
hazardous voltage potentials and heat sources inside the rectifier.
•
Keep the electronics enclosure as far as possible away from the hazardous voltage
potentials of the rectifier.
•
Use of the equipment in a manner not specified by the manufacturer can impair the
protection provided.
DynAmp does not assume liability for the customer’s failure to comply with the rules and
requirements provided in this manual.
