Things convenient to know before wiring
Two conduit connection are available and one is closed. For wiring from the top conduit, use the
following procedure:
(1) Remove the screw plug of the top conduit connection.
(2) Screw the removed screw plug into the bottom conduit connection.
(3) Insert the cable from the top and connect it.
7.2 Power voltage and load resistance
Make sure the load resistance of the wiring connected to the loop is within the range shown
below.
Note :
For Smart type, to communicate with the Hand Held Communicator (HHC) mini of 250

is required
• The unused conduit connection is of great importance to
fl
ame proof-
ing and moisture prevention. So be sure to tighten the
fl
ush screw and
packing into the connection.
• When performing an insulation check after wiring, use a Megger (insu-
lation resistance meter) of 250 V DC or less and avoid applying a high
voltage. If an arrester is equipped, avoid the insulation resistance test
and the dielectric strength measurement.
