While using this product, you may need to access other parts of a larger system. Read the safety sections of the other
components’manuals for warnings and cautions related to operating the system.
To Avoid Fire or Personal Injury
Connect and Disconnect Properly. Do not connect or disconnect terminal wiring while the wires are connected to a
voltage source.
Ground the Product. To avoid electric shock, the protective earth terminal must be connected to earth ground. Before
making connection to the input or output terminals of the product, ensure that the product is properly grounded.
Observe All Terminal Ratings. To avoid fire or shock hazard, observe all ratings and markings on the product. Consult
the product manual for further ratings information before making connections to the product. Do not usean input marked
with measurement category I for measurements within measurement categories II, III or IV. Do not connect category II
inputs directly to mains--a Class 2 CSA/UL transformer must be used for isolation.
Do Not Operate Without Covers. Do not operate this product with covers or panels removed.
Avoid Exposed Circuitry. Do not touch exposed connections and components when power is present.
Do Not Operate With Suspected Failures. If you suspect there is damage to this product, have it inspected by qualified
service personnel.
Do Not Operate in Wet/Damp Conditions.
Keep Internal Product Surfaces Clean and Dry.

3Component Identification and Descriptions
Figure 1 shows the front and right side of the RMU5 enclosure. The important features shown here are the latch and
lock attachment points. To open the RMU5 enclosure, lift the plastic latch arms away from the enclosure body, then
swing the metal straps away from the door. The door should then swing open freely. To close the enclosure, reverse
the procedure.
When the enclosure is mounted external to a rectifier cabinet, it may be desirable or even necessary for satisfying
regulatory requirements, to install a standard padlock on the latches to keep unauthorized users out of the enclosure. To
apply the padlock, knock out the two round plastic pieces on the plastic latch arms, then pass the padlock shackle through
the opening with the latch in a closed position.

Figure 2 shows the back and hinge side of the RMU5. The RMU5 may be mounted against a flat surface by driving
screws through the mounting hole locations shown in the picture. The RMU5 may also be mounted to a pipe using pipe
clamp bands through the slots shown in the picture.
Figure 2 RMU5 Back/Side View
Figure 3 shows the inside of the RMU5, which includes the front panel and bottom connectors. The front panel contains
the following features:
1. Power/Fault LED Indicator. The green indicator shows when the RMU5 is powered, and if flashing red, a fault
condition is present. If main input power is interrupted, the green indicator will flash.
2. GPS/Interrupter Status LED Indicator. This bi-color indicator shows status for the optional GPS Timing
Control Module (TCM) board and also the rectifier interruption relay status. When green, the GPS TCM board

has successfully attained a time lock to the NAVSTAR GPS network. When red, the rectifier output is switched
off (interrupted).
3. Reset/Power Down Button. The reset button may be held down for 10s to force a reset of the hardware on the
RMU5. The button may also be used to disengage the backup UPS battery when main power is removed.
4. Local Configuration USB Slave Port. This port is used for configuration of the RMU5 from a PC running
Microsoft Windows XP SP2 or higher. Further information on its use is located farther in this document.
5. 20 x 4 LCD Display With Backlight. The LCD display shows the current status of the RMU5 through a paged
display system.
6. Up/Down Control Buttons. These buttons control the page being displayed on the 20 x 4 LCD display.
7. Main I/O Connector. This connector is the principle connector for the built-in analog inputs, digital input,
interrupter relay control, and RS-485 MODBUS connections. The functions of each pin are labeled on the
faceplate.
The bottom panel contains the following features:
1. GPS Antenna Connector. This connector is only present if the RMU5 is equipped with the optional internal
GPS Timing Control Module board. Attach a 3V LNA 18dB gain GPS antenna with an SMA male connector-
terminated cable to this port.
2. Sensor Bus Expansion Connector. This port is used to attach additional analog and digital I/O modules to the
RMU5.
3. Communications Expansion Connector. This connector is used to attach RS-232 communications devices such
as digital radios, MODBUS RTUs, PSTN modems, etc. Usually an adapter board will be present according to
the communications device in use.
4. USB Host Expansion Connector. Future use connector.
5. 10/100Base-T Ethernet Connector. Allows attachment to a standard twisted pair Ethernet network.
6. Main Power Input Connector. Attach a DC power source with a voltage rating of 20 to 35V, or an AC power
source with a voltage rating of 20 to 25V to this port. When connecting a DC power source, the connections
to the main power input connector are polarity insensitive. When using an AC power source, ensure that
neither connection to the main power input connector is grounded, otherwise overheating of the RMU5 internal
power supply may result. The power source should be able to deliver at least 40VA to an RMU5 that is
equipped with additional options modules. The basic RMU5 requires approximately 5VA to operate once the
internal battery is charged, and approximately 15VA while the battery is charging (with no external loads).
Wiring may be brought into the RMU5 by drilling a hole in the lower box edge and installing water tight glands or water
proof flexible conduit connectors. When drilling the holes for the feed-through connectors, avoid drilling into the RMU
aluminum chassis.
Any Interconnection wires used must be rated to 75°C or greater.
