Emotron VSA Variable Speed Drive

Preface
Preface
To extend the performance of the product and ensure personnel
safety, read this manual thoroughly before using the
variable speed drive (VSD). Should there be any problem in
using the product that can not be solved with the information
provided in the manual, contact your nearest Emotron
distributor or sales representative who will be willing to help
you.
Precautions
The VSD is an electrical product. For your safety, there are
symbols such as “Danger”, “Caution” in this manual as a
reminder to pay attention to safety instructions on carrying,
installing, operating, and checking the VSD. Be sure to follow
the instructions for maximum safety.
WARNING: Indicates a potential hazard could
cause death or serious personal injury if
misused.
Product Inspection
The variable speed drives have all passed the function test
before delivery. Please check the following when you receive
and unpack the VSD:
• The model and capacity of the VSD is the same as those
specified on your order.
• Is there any damage caused by transportation, do not
apply the power.
Contact Emotron’s sales representatives if any of the
above problems have occurred.
Earthing
The variable speed drive must always be earthed via the
mains safety earth connection, indicated by “PE”.
Earth leakage current
This VSD has an earth leakage current which does exceeding
3.5 mA a.c. or 10 mA d.c. Therefore the minimum size of
the protective earth conductor must comply with the local
safety regulations for high leakage current equipment.
!
CAUTION: Indicates that the VSD or the
mechanical system might be damaged if
misused.
WARNING: Do not touch any circuit boards or
components if the charging indicator is still
lit after the power off is turned off.
Residual current device (RCD)
compatibility
This product cause a d.c. current in the protective conductor.
Where a residual current device (RCD) is used for protection
in case of direct or indirect contact, only a Type B
RCD is allowed on the supply side of this product. Use
RCD of 300 mA minimum.
Do not wire when the VSD is electrified. Do not check
parts and signals on circuit boards during the VSD
operation.
Do not disassemble the VSD or modify internal wires,
circuits and parts.
Earth the ground terminal of the VSD properly. As per
200 V class, earth to 100 Ohm and 400 V class, earth to
10 Ohm or below.
!
CAUTION: Do not perform a voltage test on
parts inside the VSD. High voltage will easily
destroy these semiconductor parts.
Do not connect the VSD’s T1 (U), T2 (V) and T3 (W)
terminals to an AC power supply.
CMOS ICs on the VSD’s main board are susceptible to
static electricity. Do not touch the main circuit board
