CAUTIONS FOR USE
RT-3 UNIT RELAY
4-POINT TERMINAL
Also, with the RT-3 Unit relay (PhotoMOS
Power type), be careful of the polarity on
the output side of the DC type (RT3SP1-
∗∗V
for type equipped with AQZ102).
2) We recommend the use of wire-
pressed terminals for connection to the
terminal portion.

terminal

1. Never install modules (relays) into
this product other than those
designated. Doing so will cause
malfunction, breakdown, and
breakdown of the connected product.
2. If a unit is dropped be sure to check
its external appearance and
characteristics before using it.
3. The operation and return voltage
values when equipped with PA relays
are based on the relay terminals being
face down. (RT-3 Unit relay (PA type),
4-point Terminal)
4. Switching lifetime (PA relay)
This characteristic depends on the relay
and is effected by coil driving circuit, load
type, activation frequency, activation
phase, ambient conditions and other
factors.
Also, be especially careful of loads such
as those listed below.
1) When used for AC load-operating and
the operating phase is synchronous,
rocking and fusing can easily occur due
to contact shifting.
2) Frequent switching under load
condition
When high frequently switched under
load condition that can cause arc at the
contacts, nitrogen and oxygen in the air is
fused by the arc energy and HNO
3
is
formed. This can corrode metal materials.
Three countermeasures for these are
listed here.
(1) Incorporate an arc-extinguishing
circuit.
(2) Lower the operating frequency
(3) Lower the ambient humidity
5. Operating environment
1) Keep the product as far way as
possible from power cables, high tension
equipment, power equipment, equipment
with transmitting devices such as
amateur radios, or equipment which
generates a large switching surge.
2) The main unit is made of resin;
therefore, do not use it in areas where it
may come in contact with (or be exposed
to) organic solvents such as gasoline,
thinner, and alcohol, or strong alkaline
substances such as ammonia and
caustic soda.
3) Do not use the product in areas where
it may be exposed to flammable gases,
corrosive gases, excessive dust, or
moisture, or areas where it may be
subjected to strong vibration or shock.
6. Installing and removing the module
1) Firmly insert the module into the
socket with the terminals going in the
direction of the blade receptacles.
2) The module can be easily removed
using the removal key.
(1) Insert the removal key into the socket
slots.
3) When the load is inductive, limit spike
voltages generated from the load to less
than the maximum load voltage.
Typical circuits are shown below.
(1) Add a clamp diode to the load.
Output terminals
(2) Pull the removal key up to remove the
module.
Load
(2) Add an R-C snubber to the load.

or
DC only for AQZ10∗D

(3) Slide the removal key off of the
module.
(3) Add a varistor between the output
terminals.

7. Wiring and circuit configuration
1) Perform wiring according to the
internal schematic. Take care not to make
any mistakes.
In particular, with the RT-3 Unit relay (PA
relay type) and 4-point terminal, be
careful of the polarity on the output side
when equipped with AQZ10∗D (DC type).
4) Even if spike voltages generated from
the load are limited by a clamp diode or
R-C snubber, inductances in long circuit
wires will still create spike voltages.
Keep wires as short as possible to
minimize inductance.

CAUTIONS FOR USE
8. Installation
1) Perform mounting hole cutout
according to the panel cutout drawings.
2) When installing the unit on a DIN rail,
use the DIN rail locking lever on the side
of the unit. Installation is accomplished by
simply fitting the unit onto the rail and
pressing gently.
1
First push in
the DIN rail
locking lever.

3
Press the unit onto
the DIN rail.
2
Hook the holders on the
unit over the DIN rail.
3) To remove the unit from the DIN rail,
use a flat head screwdriver to pull out the
DIN rail locking lever.
3
Remove the unit from
the DIN rail.
9. Transporting and storage
1) If the product is subjected to extreme
vibration while being transported, the
relays may become detached, the lead
may become bent, and the unit may
become damaged. Handle the carton
and case with care.
2) If the product is stored in an extremely
adverse environment, visible defects and
deterioration of performance
characteristics may result. We
recommend the following storage
conditions.
• Temperature: 5 to 30°C
41 to 86°F
• Humidity: Max. 60% R.H.
• Environment: No hazardous
substances such as sulfurous acid
gases and little dust.
10. When equipped with PhotoMOS
Power voltage drive type [RT-3 Unit
relay (PA relay type), 4-point Terminal]
Since the PhotoMOS Power voltage
sensitive type does not require the
current-controlling resistance on the input
side, it can be used together with PA
relays on RT-3 unit relay (PA relay type).
When connecting PhotoMOS Power
voltage sensitive types, since it will be a
close connection, it will be necessary to
be careful of load currents. Be sure to
refer to the information given regarding
“Load currents vs ambient temperature
characteristics” in the precautions given
for use of 4-point terminals.
