Introduction
Caution Statements
1
This symbol is used throughout this manual to draw attention to topics of
special importance to the installation and operation of MVS Series soft
starters.
Caution Statements cannot cover every potential cause of equipment damage but
can highlight common causes of damage. It is the installer's responsibility to
adhere to all instructions in this manual, to follow good electrical practice and to
seek advice before operating this equipment in a manner other than as described
in this manual.
•
Ensure that the soft starter is completely isolated from the power supply before
attempting any work on the unit.
•
Entry of metal swarf into the cabinet can cause equipment failure.
•
Do not apply voltage to the control input terminals. These are active 24 VDC
inputs and must be controlled with potential free circuits.
•
Ensure contacts or switches operating the control inputs are suitable for low
voltage, low current switching (ie gold flash or similar).
•
Ensure cables to the control inputs are segregated from AC power and control
wiring.
•
Some electronic contactor coils are not suitable for direct switching with PCB
mount relays. Consult the contactor manufacturer/ supplier to see if this is
advisable.
•
Do not connect power factor correction capacitors to the output of MVS soft
starters. If static power factor correction is employed, it must be connected to
the supply side of the soft starter.
The examples and diagrams in this manual are included solely for illustrative
