3.3 Precautions
3.3.1 Electrical Precautions
Basic electrical safety precautions should be followed to protect yourself from harm and the Device chassis from damage:
• Be aware of the locations of the power on/off switch on the chassis as well as the room’s emergency power-off switch,
disconnection switch or electrical outlet. If an electrical accident occurs, you can then quickly remove power from the
system.
• Power should always be disconnected from the system when servicing. When disconnecting power, you should rst
power down the operating system rst and then unplug the power cords. The unit has more than one power supply
cord. Disconnect two power supply cords before servicing to avoid electrical shock.
• When working around exposed electrical circuits, another person who is familiar with the power-off controls should
be nearby to switch off the power if necessary.
• Use only one hand when working with powered-on electrical equipment. This is to avoid making a complete circuit,
which will cause electrical shock. Use extreme caution when using metal tools, which can easily damage any electrical
components or circuit boards they come into contact with.
• Do not use mats designed to decrease static electrical discharge as protection from electrical shock. Instead, use
rubber mats that have been specically designed as electrical insulators.
MDU Solutions® – UCrypt® IP to Analog 2nd Generation – Installation & Operation Manual 3-1
CHAPTER 3: INSTALLATION
• The power supply power cords must include a grounding pin and must be plugged into grounded electrical outlets.
• Remove any jewelry or metal objects from your body, which are excellent metal conductors that can create short
circuits and harm you if they come into contact with printed circuit boards or areas where power is present.
• This product may be connected to an IT power system. In all cases, make sure that the unit is also reliably connected
to Earth (ground).
3.3.2 General Precautions
WARNING: The RF connections provided with this equipment are not intended for direct connection
to any outside telecommunications network or outside cable distribution plant.
WARNING: When the equipment is lifted by the front handles, always use both front handles for
security. Never lift this equipment using only a single front handle due to the weight of the equipment.
• The Devices weighs up to approximately 30 lbs (13.5kg). When lifting the system, two people should lift slowly with
their feet spread out to distribute the weight. Always keep your back straight and lift with your legs.
• While working on the system, do not wear loose clothing such as neckties and unbuttoned shirt sleeves, which can
come into contact with electrical circuits or be pulled into a cooling fan.
• After accessing the inside of the Device, close the chassis back up and secure it to the rack unit with the retention
screws and ensure that all connections have been made.
3.3.3 Chassis Precautions
• Determine the placement of each component in the rack before you install the rails.
• Install the heaviest components on the bottom of the rack rst, and then work up.
• Use a regulating uninterruptible power supply (UPS) to protect the Device from power surges, voltage spikes and to
keep your system operating in case of a power failure.
• Allow any power supply modules to cool before touching them.
3.3.4 Rack Precautions
• Ensure that the leveling jacks on the bottom of the rack are fully extended to the oor with the full weight of the rack
resting on them.
• In single rack installation, stabilizers should be attached to the rack. In multiple rack installations, the racks should
be coupled together.
• Mechanical Loading - Mounting of the equipment in the rack should be such that a hazardous condition is not
achieved due to uneven mechanical loading.
3.4 General Mechanical
• The equipment will require 1RU or 2RU of vertical rack space depending on the model being installed and may
be mounted directly above or below other equipment without providing space between, however, 1RU space is
recommended to be maintained from other equipment which generates signicant heat.
• Leave enough clearance in front of the rack to enable you to work on the chassis (~25 inches) and approximately 30
inches of clearance in the back of the rack to allow for sufcient airow and ease of servicing.
NOTE: More general information about equipment abient temperature requirements may be found
in this document from ATX Networks: http://www.atxnetworks.com/pdf/ANW1066_MDU_UCrypt_
Environment_Temp_Considerations_InfoSheet.pdf
• Rear support of the unit is mandatory and rails for attachment to rear supports are provided. Do not use the unit
chassis to support other equipment. Alternately, if rear support rails are unavailable or impractical, install the unit on
a well supported shelf.
3-2 MDU Solutions® – UCrypt® IP to Analog 2nd Generation – Installation & Operation Manual
3.5 General Electrical
• Consideration should be given to the connection of the equipment to the mains power and the effect that any
possible overloading of circuits might have on over current protection and supply wiring. Appropriate consideration of
equipment nameplate ratings of all connected equipment should be used when addressing this concern.
• Reliable earthing of rack-mounted equipment should be maintained in addition to any grounding conductor provided
in the power cord. Particular attention should be given to supply connections other than direct connections to the
branch circuit (e.g. use of power strips).
3.6 General Environment
• Be sure to maintain freedom of air movement around equipment to ensure safe operation.
• Installation of the equipment in enclosed racks is not recommended due to possibility of restricted air ow.
• Installation of the equipment in a rack should be such that the amount of air ow required for safe operation of the
equipment is not compromised.
• The equipment is designed to operate to specication in an ambient temperature of +0°C to +40°C (+35°F to +104°F),
however, normal room temperature is recommended to ensure long term operation of the equipment.
• If equipment is installed in a closed or multi-unit rack assembly, the operating ambient temperature of the rack
environment may be greater than room ambient. Therefore, consideration should be given to installing the equipment
in an environment compatible with the maximum ambient temperature (Tma) of +40°C (+104°F).
CHAPTER 3: INSTALLATION
3.7 Gigabit Ethernet Ports
The input ports are auto MDI-MDIx and intended to be connected to a network distribution switch using straight through wired
Cat5e or better quality cable. The rear panel Management Interface port allows connection to a notebook or desktop PC for

length, the cord and it’s points of connection are not strained in any way.
3.11.2 AC Power Cord Attachment
The unit AC power supply cords shall not be attached to a building surface, bundled with audio, video or RF coaxial cables,
nor run through walls, ceilings, oors and similar openings in the building structure.
3.11.3 Provision of Electrical AC Power Outlet
An AC electrical power outlet of appropriate type and rating shall be provided near the location where the unit is installed
and easily accessible such that the provided power supply cords may be routed in an appropriate manner, without the use of
extension cords, between the receptacle and the chassis. Alternately, the chassis shall be installed in close proximity to an
existing AC electrical outlet such that the requirements of this paragraph are achieved.
3.11.4 IEC C13 Power Input Cord for AC
The AC power input receptacle is a standard IEC C14 socket connector similar to that commonly used on computers and
monitors. The power cords provided with the IP2A product is a North American conguration with a NEMA 5-15 grounded
plug for 115 VAC. If it is necessary to operate the product on 230 VAC, the installer must obtain IEC C13 cords with a NEMA
6-15 grounded plug for use in North America. This may be obtained at time of order from ATX Networks or locally. If shipped
outside of North America, the Device will be supplied with an IEC C13 cord set appropriate for the locale to which it is shipped.
3.11.5 AC Input Power Requirements
When installing the equipment, it is the responsibility of the installer to determine that sufcient capacity is available in the
electrical circuit feeding the unit to avoid overloading the supply circuit. The AC model will require power to be supplied from a
properly grounded AC outlet. The installer shall determine that the AC power outlet, its wiring and receptacle is in compliance
with local and/or national electrical codes as applicable. The AC input power requirement is constant over the range of input
voltages. At higher input voltages, the current consumption is lower than it is at lower voltages where the input current is higher.

3.12 DC Power Supplies
3.12.1 DC Power Supply Connections
The optional redundant DC switching type power supply system is intended to operate on nominal -48 VDC power systems
but functions between -40 and -57.2 VDC. A pair of insulated #12 AWG DC power wires must be eld installed for each of the
two modules using permanent wiring methods. Wire insulation colors must be different for each of the two conductors clearly
indicating the polarity of the voltage. It is recommended that stranded conductors be used for DC power and that RED wire be
used for the 0V conductor and BLACK for the -48V conductor. Crimped on style Ring or Spade terminals may be used and it
is also permissible to strip the wire 8mm, twist the stranded conductors tightly and clamp the wire in the provided wire clamp
as illustrated in Figure 3-11.
CHAPTER 3: INSTALLATION
Figure 3-11: DC Power Module Connections
3.12.2 DC Disconnect and Fusing
Each DC power module should be externally fused or otherwise adequately protected at no more that 20 Amperes and
must be provided with it’s own external readily accessible disconnect device. Each disconnect must be prominently labeled
indicating the units being powered and with adequate instructions for the removal of all power from the unit being serviced.
The disconnect must be turned off for BOTH power modules before removing supply wires from the module terminal blocks
when replacing a power supply module or otherwise servicing the unit.
3.13 Power Supply Redundancy
For the redundant power supplies, either power module on its own can provide the required power safely if one fails. To retain
the redundancy feature, replace a failed power module as soon as possible. A power module failure or the failure of the supply
current or protection fuse will be indicated by an audible alarm within the encoder power modules and the green power status
LED on the power module will be extinguished. Silence the audible alarm with the red rear panel Alarm Reset switch adjacent
to the power supply modules, Figure 3-12.

3.13.1 Redundant Power Module Replacement
AC Version
WARNING: The power cords for BOTH power modules must be disconnected before attempting
to remove the power modules or otherwise servicing the unit.
Power module failure will be indicated by the alarm being sounded and the green status light on the module will no longer be
lit. This power module may be replaced by rst disconnecting the AC power cord from the IEC input socket of BOTH power
modules, then release the module by pressing to the left on the thumb latch at the bottom of each module. Extract the module
and replace with an identical replacement module only.
