Applications
10) Do not drop wire chips into the holes
of vent when wiring, because they could
cause fire, malfunction or trouble with the
device.
11) To prevent the unit from harmful
effects of unexpected high level noise, it
is recommended that a surge absorber
be installed between the electromagnetic
switch coils.
3. NOTICE ON THE MOUNTING
1) Do not use excessive force while
screwing in the mounting bracket of KT4,
8, 9, 4H and 4B series. For KT4, 8 and 9
series, recommended torque is approxi-
mately 0.12N·m. For KT4H and 4B,
recommended torque is approximately
0.05 to 0.06 N·m.
2) When mounting the KT7 series to the
DIN rail, mount it in a lateral direction.
Make sure a click is audible when fixed
into place.
4. OPTIONAL HEATER BURN-OUT
ALARM OUTPUT (KT4, 7, 8, 9, 4H and
4B series)
1) This alarm is not available for detecting
current under phase control.
2) Use the current transformer (CT)
provided, and pass one lead wire of the
heater circuit into the hole of CT.
3) When wiring, keep CT wire away from
AC source and load wire to avoid external
interference.
4) In three phase installations, ensure
that R, S, and T are each connected to a
2-line CT that connects with CT1 ((13)–
(14)) and CT2 ((14)–(15)) terminals.
5. Please use rod terminals for the
terminal portion of the KT7 series.
We recommend terminals made by
Phoenix Contact.
(1) to (4) are AI0.25–8YE, AI0.34–8TQ,
AI0.5–8WH, AI0.75–8GY, AI1.0–8RD,
and AI1.5–8BK.
(5) to (9) are AI0.25–8YE, AI0.34–8TQ,
and AI0.5–8WH.
The screw tightening torque for (1) to (4)
should be no more than 0.5 N·m and for
(5) to (9) it should be no more than 0.25
N·m. Make sure no screw is loose.
