1 Getting Started
1.1 Description
RT431 - Time Signal Distributor is an electrical signal multiplier. It multiplies IRIG-B demodulated, PPS or
any signal with a voltage between 0 and 5 V d.c., to frequencies up to 5 MHz, through electrical and optical
outputs, allowing the synchronization of IEDs. The equipment ensures time accuracy based on the accuracy of
the time reference source that is being used in the input.
The equipment has up to 10 electrical outputs with a 150 mA individual supply capacity and up to 10 optical
outputs for multimode fiber and ST connector.
It also has frontal indicators for monitoring the received synchronism signal and voltage of the primary supply.
1.2 Unpacking
Unpack the equipment carefully and make sure all the accessories and cables are put aside so they will not
be lost. Check the contents against the packing list that goes with the product. If any of the content listed is
missing, please contact Reason (see contact information at the beginning of this manual).
Examine the equipment for any shipping damage. If the equipment is damaged or fails to operate, notify the
shipping company without delay. Only the consignee (the person or company receiving the equipment) can file
a claim against the carrier for shipping damage.
We recommend you keep the original packing materials for eventual future transport.

4 Installation
4.1 Mounting
RT411 has been designed to be mounted in a standard 19-inch rack using four M6x15 screws to affix. Allow
adequate clearance for all connections.
In particular, the optical fiber cables should be installed respecting a minimum bend radius of 30 mm.
For more information about dimensions of the equipment, see Chapter 2.
4.2 Environment
Temperature and relative humidity should not exceed the limits stated in Chapter 2. We recommend providing
appropriate heating or cooling measures to ensure that these limits are respected at all times.
4.3 Power Supply
The equipment can be powered from DC or AC power within the limits specified in Chapter 2.
All power connections should use insulated flameproof flexible cable (BWF type) with a 1.5 mm2cross section,
70◦C thermal class, and 750 V insulation voltage.
To reduce the risk of electrical shock, pre-insulated tubular pin terminals should be used in the ends of power
connections.
Figure 5: Pre-insulated tubular pin terminals
The pin terminals should be completely inserted into the connectors supplied with the equipment, so that no
metallic parts are exposed. Refer to the figure below to insert it correctly.
A 1.5 mm2ground lead shall be connected to the terminal marked with the protective earth symbol for safety.
For optimal electromagnetic compatibility, ground the equipment by using a 10 mm wide grounding strap to
connect the frame of the equipment to a good ground point on the mounting rack.

4.3.1 AC Power Connection
Phase (F) should be applied to terminal 1 and neutral to terminal 2, as shown in Figure 7.
Figure 7: AC power connection
The installation of an external 10 A, category C, unipolar circuit breaker near the equipment is recommended.
The circuit breaker should have an interruption capacity of at least 25 kA and comply with IEC 60947-2 stan-
dard.

The installation of an external 10 A, category C, unipolar circuit breaker near the equipment is recommended.
The circuit breaker should have an interruption capacity of at least 25 kA and comply with IEC 60947-2 stan-
dard.
4.4 Powering Up
1. Connect the power supply (including the ground lead) to the appropriate terminals. After connecting the
power supply, the POWER indicator will light up.
2. If the time signal is already connected to the electrical or optical synchronism input, the ACT indicator
will start blinking according to the frequency of the time signal.
3. In case the equipment does not behave in a way here described, carefully check all power and signal
connections.
4. To turn off the equipment, disconnect the power supply. All front panel indicators will turn off.
4.5 Time Reference Inputs
RT411 has an optical and electrical input for time reference, as shown in Figure 9. The optical and electrical
synchronism inputs accept IRIG-B00X, PPX, DCF77, signals with a voltage between 0 and 5 V d.c., and
frequency up to 5 MHz.
RT411 - User Manual [rt411-manual-en rev 1.1]
Reason Tecnologia S.A. 17
Figure 9: Electrical and Optical Inputs of time synchronism
To synchronize the equipment using optical fiber, adequate optical fiber should be used, respecting a minimum
bend radius of 30 mm, according to Chapter 2.
To synchronize the equipment using the electrical input, it is recommended the use of twisted pair.
For distances over 3 m, the use of an optical fiber cable is recommended to minimize the effects related to EMC.
The length of the optical fiber cables should not exceed 2 km.
4.5.1 Selection of the Time Reference Input
An electrical jumper allows selecting the input to be used as time reference. Making the connection in the
INPUT SELECTION connector, as shown in Figure 10, the electrical time reference port is enabled. In case the
jumper is disconnected, the equipment operates using the optical time reference port.
Figure 10: to select the time reference input (if connected, enables the electrical input)
The jumper connections should use insulated flameproof flexible cable (BWF type) with a 1.5 mm2cross sec-
tion, 70◦C thermal class, and 750 V insulation voltage.
