POINTS OF CAUTION
■
ENVIRONMENT
•
Indoor use.
•
When heavy dust or metal particles are present in the
air, install the unit inside proper housing with sufficient
ventilation.
•
Do not install the unit where it is subjected to continuous
vibration. Do not subject the unit to physical impact.
•
Environmental temperature must be within -25 to +85°C
(-13 to +185°F) with relative humidity within 30 to 90%
RH in order to ensure adequate life span and operation.
•
This unit needs a DIN rail as earth grounding bar. Ox-
ide coating of an aluminium rail may lower the electric
conductivity between this module and the ground. Use a
steel or copper rail.
■
DIELECTRIC STRENGTH TESTING
•
The surge protector starts discharging when 160V or
greater voltage (with floating shield type) or several volts
(with grounding shield type) is applied between lines and
earth. Remove the grounding wire before conducting a
test. Be sure to return the wire after the test.
■
AND ....
•
We recommend that you keep spare surge protectors so
that you can replace them when necessary.
•
Lightning surge can enter not only through signal lines
but also through power supply lines. We recommend that
you also use the Lightning Surge Protector for Power
Lines for adequate protection.

INSTALLATION
Mount the unit on a DIN rail. Once installed, do not move
it to another DIN rail.
■
MOUNTING THE UNIT ON A DIN RAIL
A) Hang the upper hook of the DIN rail mounting adaptor at
the rear side of unit, on the DIN rail.
B) Push in the lower in keeping pressing the unit to the DIN
rail.
C) DIN rails generally have slight individual variability in
size. If you find it difficult to push in the lower part, go
back to (A) and hang the upper part more deeply onto the
rail and try (B) again.
