1)
When
using
an
RS
‐
485
bus
connection,
it
is
advisable
to
connect
the
IPES
‐
IR/UV
to
the
bus
via
the
terminal
box.
To
connect
the
detector
to
the
terminal
box,
use
a
cable
not
longer
than
1.64
feet
(0.5
m).
The
cable
characteristics
should
meet
the
requirement
of
the
cable
entries
mounted
on
the
IPES
‐
IR/UV
casing
and
those
of
the
terminal
box.
2)
Arrange
the
power
‐
supply
system
so
that
the
power
‐
supply
voltage
across
the
device
terminals
ranges
from
18
to
32
V
(taking
into
account
the
IPES
‐
IR/UV
consumption).
