Federal Communications Commission Radio Frequency Interference
Statement
This equipment has been tested and found to comply with the limits for a Class A digital device
pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection
against harmful interference when the equipment is operated in a commercial environment. This
equipment generates, uses and can radiate radio frequency energy and, if not installed and used in
accordance with the instruction manual, may cause harmful interference to radio communications.
Operation of this equipment in a residential area is likely to cause harmful interference in which
case the user will be required to correct the interference on his own expense.
Warning: Changes or modifications not expressly approved by RuggedCom Inc. could void the
user’s authority to operate the equipment.
Caution – This product contains a laser system and is classified as a
“CLASS 1 LASER PRODUCT”
Caution – Use of controls or adjustments or performance of procedures other than those specified
herein may result in hazardous radiation exposure. This product contains no user serviceable
parts. Attempted service by unauthorized personnel shall render all warranties null and void.
Should this device require service see the “Warranty and Service” section of this installation guide.
Important:
The RuggedMCTM should be installed in a restricted access location where access can only be
gained by service personnel or users who have been instructed about the reasons for the
restrictions applied to the location and about any precautions that shall be taken; and access is
through the use of a tool or lock and key, or other means of security, and is controlled by the
authority responsible for the location.

1 Product Overview
1.1 Functional Overview
The Rugged MediaConverterTM is an industrially hardened fiber optical media converter
specifically designed to operate in harsh environments such as those found in electric utility
substations and factory floors. The RMC40TM provides industrial strength Ethernet copper-to-fiber
media conversion, providing copper-based 10BaseT or 100BaseTx clients 100BaseFX fiber optical
connectivity.
Specifically tested to the same standards as mission critical protective relaying equipment (i.e.
ANSI/IEEE C37.90 and IEC 60255), and the newly issued IEC 61850-3 “Communications Systems
and Networks in Substations” standard, the RuggedMCTM is ideally suited for substation or
industrial environments. The reliability of the Rugged MediaConverterTM family exceeds that of
commercial media converters by having no rotating mechanical parts (i.e. no cooling fans), utilizing
high-temperature solid state components and incorporating the necessary transient and surge
suppression circuitry required for substation and harsh industrial environments.

Feature Highlights
Utility Grade (i.e. substation hardened) per ANSI/IEEE C37.90, IEC 60255, and the new IEC
61850-3 (2002), IEC 61000-6-5 standards
Operating temperature: -40° to 85°C (no fan)
Radiated RF Immunity: 35V/m per ANSI/IEEE C37.90.2
Power supply options: 24 (10-36VDC), 48 (36-72) or HI (88-300VDC / 85-264VAC)
2 – 10/100BaseTx RJ45 style auto-negotiating Ethernet ports
Choice of one of the following:
With the use of an optional panel-mount adapter, the RuggeMCTM series of media converters can
be panel mounted. The drawing shown in Figure 2.2.1 shows an example of an RMC unit panel
mounted using the optional panel mount adapter.
The panel mount adapter can be secured to a panel with three screws. The RuggedMCTM product
is easily mounted onto the panel mount adapter via the two metal clips on either side of the unit,
and a single screw located on the bottom.

2.3 Power Supply Wiring and Grounding
Fig. 2.2.1 RuggedMCTM Power Supply Inputs
The RuggedMCTM power supply inputs are identical and are connected as follows:
1. +/L = DC (+) / AC (Hot) is connected to the positive (+) terminal if the power source is DC
or to the (Hot) terminal if the power source is AC.
2. -/N = DC (-) / AC (Neutral) is connected to the negative (-) terminal if the power source is
DC or to the (Neutral) terminal if the power source is AC.
3.Surge Ground is connected to the Chassis Ground via a braided cable or other
appropriate grounding wire. Surge Ground is used as the ground conductor for all surge
and transient suppression circuitry internal to the RuggedMCTM.
Chassis Ground is connected to the Safety Ground terminal for AC inputs or the
equipment ground bus for DC inputs.
Note: Surge Ground must be disconnected from Chassis Ground during HIPOT
(dielectric strength) testing.
Notes:
1. For 125/250VDC rated equipment: An appropriately rated 300VDC circuit breaker
must be installed within 3 meters of unit.
2. For 110/230VAC rated equipment: An appropriately rated 250VAC circuit breaker
must be installed within 3 meters of the unit
3. A circuit breaker is not required for 48 or 24VDC rated equipment.
4. For multiple supplies, separate circuit breakers must be installed. Equipment must
be installed according to the applicable country wiring codes.

2.4 RJ45 Ports – Signal Description
The RJ45 port accepts standard category 5 unshielded twisted pair (UTP), or screened twisted pair
(STP) cable with RJ45 male connectors. Fig. 2.3.1 shows the RJ45 port pin configuration. Both
RJ45 Ethernet ports on the RMC40TM are auto-crossover, auto-polarity, auto-crossover (MDI /
MDIX) equipped, for simple plug-and-play operation.
Although transient suppression circuitry is present on all RJ45 ports, they cannot protect the port
from high-amplitude, high-energy transients that can potentially damage the RMC40TM and its link
partners. In general, RuggedCom strongly recommends limiting connections used by the RJ45
ports to those that are less than 3m in length, or limited to environments sufficiently protected from
such transients.

NOTE:
For substation applications it is not recommended to use these ports to interface to
field devices across distances which could produce high levels of ground potential rise
(GPR), (i.e. greater than 2500V) during line-to-ground fault conditions.
1. Maximum segment length is greatly dependent on factors such as fiber quality, and
number of patches and splices. Please consult RuggedCom sales associates when
determining maximum segment distances.
2. To convert from average to peak add 3 dBm. To convert from peak to average, subtract 3
dBm.
