Safety
Before installation:
Read the user guide completely and gather all information on the unit. Make sure
that you understand it fully. Check that your application does not exceed the safe
operating specifications for this unit.
This unit should only be installed by qualified personnel.
This unit should be built-in to an apparatus cabinet, or similar, where access is
restricted to service personnel only.
The power supply wiring must be sufficiently fused, and if necessary it must be
possible to disconnect manually from the power supply. Ensure compliance to
national installation regulations.
This unit uses convection cooling. To avoid obstructing the airflow around the unit,
follow the spacing recommendations.
Before mounting, using or removing this unit:
Prevent access to hazardous voltage by disconnecting the unit from power supply.
Warning! Do not open connected unit. Hazardous voltage may occur within this
unit when connected to power supply.
Care recommendations
Follow the care recommendations below to maintain full operation of unit and to fulfil
the warranty obligations.
This unit must not be operating with removed covers or lids.
Do not attempt to disassemble the unit. There are no user serviceable parts inside.
Do not drop, knock or shake the unit, rough handling above the specification may cause
damage to internal circuit boards.
Do not use harsh chemicals, cleaning solvents or strong detergents to clean the unit.
Do not paint the unit. Paint can clog the unit and prevent proper operation.
Do not expose the unit to any kind of liquids (rain, beverages, etc). The unit is not water-
proof. Keep the unit within the specified humidity levels.
Do not use or store the unit in dusty, dirty areas, connectors as well as other mechanical
part may be damaged.
Fibre connectors are supplied with plugs to avoid contamination inside the optical port.
As long as no optical fibre is mounted on the connector, e.g. for storage, service or
transportation, should the plug be applied.

Note. Fibre Optic Handling
Fibre optic equipment needs special treatment. It is very sensitive to dust and dirt. If
the fibre will be disconnected from the modem the protective hood on the transmitter/
receiver must be connected. The protective hood must be kept on during transportation.
The fibre optic cable must also be handled the same way.
If this recommendation not will be followed it can jeopardise the warranty.
Cleaning of the optical connectors
In the event of contamination, the optical connectors should be cleaned by the use of
forced nitrogen and some kind of cleaning stick.
Recommended cleaning fluids:
• Methyl-, ethyl-, isopropyl- or isobutyl-alcohol
• Hexane
• Naphtha
Maintenance
No maintenance is required, as long as the unit is used as intended within the specified
conditions.

General
RPW600 Pilot Wire modems are used with RED615 line differential protection and
control IEDs to enable the galvanic protection communication connection over twisted
pair media, better known as Pilot Wire in the area of line differential protection
applications.
Two different variants of the RPW600 modems are available, a master (RPW600M) and
a follower (RPW600F) which always are needed to be used as counterparts in pilot wire
communication link. To enable ease of use, no setting or configuration is needed with
either of the RPW600 modem variants.
Pilot wire link lengths typically up to 8 km with 0.8 mm2 twisted pair cables can be
applied. With twisted pair cables in good condition even longer distances can be
achieved. The achieved link length also depends on the noise levels in installations.
As important part of the line differential protection scheme the RPW600 modems
fulfill the same EMC- and environmental standards as RED615 line differential protection
and control IEDs. The pilot wire connection in the RPW600 modem caters for 5 kVac
(RMS, 1 min) level insulation against earth potential as a standard.

Diagnostic
QoS indication
The QoS indication on the front of the unit gives an indication of the pilot wire link sta-
tus.
If indication shows weak link it is recommended to improve the pilot wire characteristic.
A weak link can be unstable and result in data transmission losses.
RPW-diagnostic tool connection
The RPW-diagnostic tool, which is part of the RPW-
diagnostic kit, can be used for more advanced diagnostic
and logging of diagnostic parameters. Connection to the
RPW-unit is possible via the
console port in the front of the unit using the serial con-
sole cable, also part of the diagnostic kit.
The following steps needs to be taken
1. Connect the serial diagnostic cable to the console port.
(Use only the cable provided in Diagnostic Kit).
2. Connect cable to your computer
(USB port, if drivers are needed they can be found on the CD in the RPW-diagnostic kit).
3. From RPW-diagnostic tool connect to the assigned port.
RPW-diagnostic tool
The RPW-diagnostic tool has a built in help. Set the pointer over a specific item and
information about that part will pop-up automatically.

Mounting
This unit should be mounted on 35 mm DIN-
rail, which is horizontally mounted inside an
apparatus cabinet or similar. Snap on mounting,
see figure.
Earth connection
For correct function the ground connection on
the unit needs to be properly connected to a solid
ground. See figure.
Removal
Press down the support at the back of the unit
using a screwdriver. See figure.
Cooling
This unit uses convection cooling. To avoid
obstructing the airflow around the unit, use the
following spacing rules. Minimum spacing 25 mm
(1.0 inch) above / below and 10 mm (0.4 inches)
left / right the unit. Spacing is recommended
for the use of unit in full operating temperature
range and service life.
