Use Precautions Of High Voltage DC Contactors
1. Contacts with the polarity of contactor,please operate according to the product identification promp.
2. Do not use fallen products.
3.Avoid installing products in strong magnetic fields(near transformers or magnets) or near objects with thermal radiation.
4.
The
product
with
energy
saver
has
a
reverse
surge
absorber
circuit,so
there
is
no
need
to
use
surge
protector.
5.About
0.1
seconds
after
the
product
with
energy
saving
board
is
connected
to
the
power
supply,the
circuit
starts
to
switch
automatically.Do
not
turn
off
repeatedly
at
the
same
position,otherwise
the
contactor
energy
saving
board
may
be
damaged.
6.
About
the
load
life:
This
contactor
is
a
high
voltage
DC
switch,please
do
not
exceed
its
switching
ability
and
life
parameters
in
the
state
of
use,otherwise
may
lose
the
ability
to
cut
off.Please
replace
if
necessary.
7.
If
the
coil
and
contacts
of
the
contactor
are
continuously
connected
to
the
rated
voltage(or
current),the
power
supply
is
cut
off
and
then
switched
on
immediately,then
the
resistance
of
the
coil
will
increase
as
the
temperature
of
the
coil
increases,thus
increasing
the
pick-up
voltage
of
the
product
and
possibly
leading
to
excess
of
the
rated
suction
voltage.In
this
case,the
follwing
measures
should
be
taken:
such
as
reducing
the
load
current,limiting
the
duration
of
power
on
or
using
coil
voltage
higher
than
the
rated
pick-up
voltage.
