Connection Of Wiring - Fujitsu AIRSTAGE ARXC36GATH Installationsanleitung

When using solid core cables, do not use the ring terminal. If you use the solid core
cables with the ring terminal, the ring terminal's pressure bonding may malfunction
and cause the cables to abnormally heat up.
B. For strand wiring
(1) Use ring terminals with insulating sleeves as shown in the fi gure below to connect to
the terminal block.
(2) Securely clamp the ring terminals to the cables using an appropriate tool so that the
cables do not come loose.
(3) Use the specifi ed cables, connect them securely, and fasten them so that there is no
stress placed on the terminals.
(4) Use an appropriate screwdriver to tighten the terminal screws. Do not use a
screwdriver that is too small, otherwise, the screw heads may be damaged and
prevent the screws from being properly tightened.
(5) Do not tighten the terminal screws too much, otherwise, the screws may break.
(6) See the table for the terminal screw tightening torques.
(7) Please do not fi x 2 power supply cables with 1 screw.

To peel the fi lm from the lead cable, use a dedicated tool that will not damage the
conductor cable.
When installing a screw on the terminal block, do not cut the cable by overtightening
the screw. On the other hand, an undertightened screw can cause faulty contact, which
will lead to a communication failure.
