40ºC.
The operating temperature of the indicator/alarm unit is -10 to 40ºC. The indicator/alarm unit must be
installed in a stable place where the operating temperature is maintained and does not change suddenly.
- 15 - RM-5000
4 How to Use 4-3. Precautions for system designing
Do not install the indicator/alarm unit in a place exposed to direct sunlight or sudden changes in the
temperature.
When you select installation sites, avoid a place where it is exposed to direct sunlight or radiant heat
(infrared rays emitted from a high-temperature object), and where the temperature changes suddenly.
Condensation may be formed inside the indicator/alarm unit, or the indicator/alarm unit cannot adjust to
sudden changes in the temperature.
Keep the indicator/alarm unit (and its cables) away from noise source devices.
When selecting installation points, avoid a place where high-frequency/high-voltage devices exist.
Do not install the indicator/alarm unit in a place where maintenance of the indicator/alarm unit cannot be
performed or where handling the indicator/alarm unit involves dangers.
Regular maintenance of the indicator/alarm unit must be performed.
Do not install the indicator/alarm unit in a place where the machinery must be stopped when maintenance is
performed in its inside, where parts of the machinery must be removed to perform maintenance, or where
the indicator/alarm unit cannot be removed because tubes or racks prevent access to it. Do not install the
indicator/alarm unit in a place where maintenance involves dangers, for example, near a high-voltage cable.
Do not install the indicator/alarm unit in machinery which is not properly grounded.
Before installing the indicator/alarm unit in machinery, the machinery must be grounded properly.
Do not install the indicator/alarm unit in a place where other gases exist around it.
The indicator/alarm unit must not be installed in a place where other gases exist around it.
4-3. Precautions for system designing
CAUTION
An unstable power supply and noise may cause malfunctions or false alarms.
The descriptions in this section must be reflected on the designing of a system using the
indicator/alarm unit.
Using a stable power supply
The external output and alarm contact of the indicator/alarm unit may be activated when the power is turned
on, when momentary blackout occurs, or when the system is being stabilized. In such cases, use a safety
power supply, or take appropriate actions on the receiving side.
The indicator/alarm unit must be provided with the following power supply.
Power supply
voltage
Allowed time of
momentary
blackout
Others
Heat radiation designing
When it is installed in the closed instrumentation panel, attach ventilation fans above and below the panel.
Introducing protective measures against lightning
If cables are installed outside the factory/plant, or if internal cables are installed in the same duct as the
cables coming from outside the factory/plant, "lightning" will cause problems. Because lightning acts as a
large emission source while cables act as a receiving antenna, devices connected to the cables may be
damaged.
24 VDC (21.6 – 26.4 VDC) (Terminal voltage of the indicator/alarm unit)
Up to 10 milliseconds
(To recover from the momentary
blackout for 10 milliseconds or more,
restart the indicator/alarm unit.)
Do not use it with a power supply of
large power load or high-frequency
noise.
Example of actions
To ensure continuous operation and
activation, install a protective power
supply outside the indicator/alarm unit.
Example of actions
Use a line filter to avoid the noise source
if necessary.
RM-5000 - 16 -
4 How to Use 4-3. Precautions for system designing
Lightning cannot be prevented. Cables installed in a metal conduit or under the ground cannot be
completely protected from inductive lightning surge caused by lightning. Although complete elimination of
disasters caused by lightning is impossible, the following protective measures can be taken.
Take appropriate measures in accordance with the importance of the facilities and the
environment.
• Connect the transmission signal route by using optical fiber.
Protection
against lightning
Grounding
* The lightning arrester has a circuit to remove a surge voltage which damages field devices, so that
signals may be attenuated by installing the arrester. Before installing a lightning arrester, verify that it
works properly.
Proper use of alarm contact
The alarm contact of the indicator/alarm unit is used to transmit signals to activate an external buzzer or
alarm lamp. Do not use the indicator/alarm unit for controlling purpose (e.g., controlling the shutdown valve).
CAUTION
The "b" contact (break contact) under de-energized state may be opened momentarily by a physical
shock, such as external force.
When the "b" contact is selected for the alarm contact, take appropriate actions to prepare for a
momentary activation, for example, add signal delay operation (approximately one second) to the
receiving side of the "b" contact.
The specifications for the alarm contact of the indicator/alarm unit are based on the resistant load conditions.
If inductive load is used at the alarm contact, the following errors will occur easily because counter
electromotive force is generated at the contact.
• Deposition, defective insulation or defective contact at the relay contact
• Damage of any electric parts due to high-voltage generated inside the indicator/alarm unit
• Abnormal operations by an out-of-control CPU
CAUTION
• In principle, do not activate inductive load at the alarm contact of the indicator/alarm unit. (In
particular, never use the inductive load to activate a fluorescent lamp or motor.)
• If inductive load is activated, relay it with an external relay (contact amplification). However,
because the coil of an external relay also involves inductive load, select a relay at a lower
voltage (100 VAC or below), and then protect the contact of the indicator/alarm unit with an
appropriate surge absorbing part, such as a CR circuit.
• Provide protection by a lightning arrester (cable arrester).
(Although inductive lightning surge can be transmitted through the cable, it is
prevented by installing a lightning arrester before the field devices and central
processing equipment. For information on how to use a lightning arrester, please
contact the manufacturer.)
In addition to lightning, there are more sources of surge noise. To protect units from
these noise sources, the units must be grounded.

4 How to Use 4-3. Precautions for system designing
A
If load is to be activated, appropriate measures must be taken to stabilize the operation of the
indicator/alarm unit and protect the alarm contact referring to the following information.
• Relay it with an external relay at a lower voltage of 100 VAC or below (contact amplification). At the same
time, the surge absorbing part SK1 suitable for the specifications must be attached to the external relay.
• In addition, the surge absorbing part SK2 must be attached to the loaded side of the external relay if
necessary.
• It may be recommended that the surge absorbing part should be attached to the contact for certain load
conditions. It must be attached to an appropriate position by checking how the load is activated.

•
Connection conditions
• Cable: 0.08 - 2.5 mm
• Bare wire length: 8 - 9 mm
• Connecting tools: Dedicated screwdrivers manufactured by WAGO and equivalent (edge width 3.5 x 0.5
mm or less)
CAUTION
The specified bare wire length must be observed when the wire insulation is peeled off.
Improper clamping of the wire due to a shorter bare wire length may cause defective electric
conduction or heating.
Catching the wire insulation due to a shorter bare wire length may cause defective electric
conduction or heating.
Exposing the wire due to a longer bare wire length may cause defective insulation or a short circuit.
Be careful not to break up the wire. If the wire is broken up when inserted to the terminal, this may
cause defective insulation or heating.
Compatible bar terminal
For a bar terminal, the following items are available.
• Bar terminal (ferrule): Model 216 Series (manufactured by WAGO)
• Crimping tool: Model VarioCrimp 4 (206-204) (manufactured by WAGO)
CAUTION
A bar terminal of the specified model must be used. Using other bar terminals invalidates the
warranty of the performance.

<How to Connect to Terminal Plate>
When cables are connected to the terminal plate, use the dedicated screwdriver or a compatible flathead
screwdriver to do so as shown below.
CAUTION
The right tools must be used. Only one wire can be connected to one wiring hole.
When the wire is inserted into the driver slot by mistake, it does not contact the conductive part. This
may cause defective electric conduction or heating.
When the wire is inserted under the spring by mistake, it does not contact the conductive part. This
may cause defective electric conduction or heating.
Wiring: Perform wiring as shown in the figure below.
(1) Insert the screwdriver at an
angle into the operating slot
(square hole).
(4) Properly peel off a wire and
insert it into the wiring hole
(round hole).
The wire will go in smoothly
if you insert the wire along
the edge of the round hole.
(2) While standing the
screwdriver upright, insert it
all the way securely.
(5) When the wire is inserted as
far as it will go, pull out the
screwdriver while holding
the wire.
(3) If you have done the previous
steps properly, the screwdriver is
kept upright when you let it go.
(6) To check whether the wire is
connected securely, pull the wire
gently.
(Do not pull the wire strongly.)
Removal: In the same way as for the wiring procedure, insert the screwdriver to remove the wire.
