Precautions
Refer to the
CompoBus/S Operation Manual (W266) before using
the Terminal.
The following precautions are the same for all SRT1 Terminals.
Refer also to the precautions specified for individual Terminals.
General Safety Precautions
Wiring
Turn OFF the Unit before wiring the Unit and do not remove the ter-
minal block cover or touch the terminal block while the Unit is turned
ON, otherwise an electric shock may occur.
Do not impose any voltage other than the rated voltage on the input
terminal. Doing so may result in damage to the Unit or cause the Unit
to malfunction.
Relay I/O Type
SRT1-ROC08 and SRT2-ROC16
Do not connect the Unit to loads operating at any voltage or con-
suming a total current exceeding the permissible switching voltage
or current of the Unit. Doing so may result in the faulty insulation,
contact weld, or faulty contact of the relays, or damage to the relays,
or cause the relays to malfunction or burn.
The life of a relay varies with the switching condition. Test the relays
under the actual operating conditions before using the relays within
the permissible switching frequency. The use of deteriorated relays
may result in the faulty insulation of the relays or cause the relays to
burn.
Do not use the Unit in places with inflammable gas. Doing so may
result in a fire or explosion due to the heat of the relays or a spark
from the relays when they are switched.
Transistor, Power MOS FET, and SSR I/O Types
SRT1-OD04, SRT2-OD08, SRT2-OD16, SRT1-OD16P,
SRT1-ROF08, and SRT2-ROF16
Do not connect the Unit to loads consuming a total current exceed-
ing the rated output current of the Unit. Doing so may damage the
output element and a short or open-circuit malfunction may result.
If the Unit is connected to a DC inductive load, connect a diode to the
Unit to protect the Unit from counter-electromotive voltage, other-
wise the counter-electromotive voltage may damage the output ele-
ment and a short or open-circuit malfunction may result.
Correct Use
Replacing Relays
Use the relay removal tool to the left of the screw terminals to
replace relays.
Turn OFF the Unit to replace relays, otherwise an electric shock
may occur or the Unit may malfunction.
Installation Environment
Do not install the Unit in the following places. Doing so may result in
damage to the Unit or cause the Unit to malfunction.
•
Places with direct sunlight.
•
Places with ambient temperature ranges not within 0
°
C to 55
°
C.
•
Places with rapid temperature changes resulting in condensa-
tion or relative humidity ranges not within 10% to 90%.
•
Places with corrosive or inflammable gas.
•
Places with excessive dust, salinity, or metal powder.
•
Places with vibration or shock affecting the Unit.
•
Places with water, oil, or chemical sprayed on the Unit.
Screw Tightening Torques
Tighten all screws of the Unit properly, otherwise the Unit may mal-
function.
•
Tighten each terminal screw to a torque of 0.6 to 1.18 N
S
m (6.2
to 12.0 kgf
S
cm).
•
Tighten each mounting screw to a torque of 0.6 to 0.98 N
S
m (6.2
to 10.0 kgf
S
cm).
Terminal screws
Mounting screws
Cleaning
Use alcohol or benzine to clean the surface of the Unit. Do not use
paint thinner to clean the surface, otherwise the surface will be dam-
aged or discolored.
Handling
Do not drop the Unit or shock or vibrate the Unit excessively. Doing
so may result in damage to the Unit or cause the Unit to malfunction.
Disassembling, Repairing, and Modifying
Do not disassemble, repair, or modify the Unit, otherwise an electric
shock may occur or the Unit may malfunction.
