any maintenance tasks, make sure all power to the device has been disconnected and wait
approximately two minutes for any remaining energy to dissipate.
IMPORTANT!
This product contains no user-serviceable parts. Attempted service by unauthorized personnel shall
render all warranties null and void.
Changes or modifications not expressly approved by Siemens AG could invalidate specifications, test
results, and agency approvals, and void the user's authority to operate the equipment.
IMPORTANT!
This product should be installed in a restricted access location where access can only be gained by
authorized personnel who have been informed of the restrictions and any precautions that must be
taken. Access must only be possible through the use of a tool, lock and key, or other means of security,
and controlled by the authority responsible for the location.

Section 2.1
Mounting the Device
The RX1500 is designed for maximum mounting and display flexibility. It can be equipped with connectors that
allow it to be installed in a 48 cm (19 in) rack, 35 mm (1.4 in) DIN rail or directly on a panel.
NOTE
For detailed dimensions of the device with either rack, DIN rail or panel hardware installed, refer to
Chapter 5, Dimension Drawings.

6 Mounting the Device to a Rack
The following sections describe the various methods of mounting the device:
•Section 2.1.1, “Mounting the Device to a Rack”
•Section 2.1.2, “Mounting the Device on a DIN Rail”
•Section 2.1.3, “Mounting the Device to a Panel”
Section 2.1.1
Mounting the Device to a Rack
For rack mount installations, the RX1500 can be equipped with rack mount adapters pre-installed at the front or
rear of the chassis. Additional adapters are provided to further secure the device in high-vibration or seismically
active locations.
CAUTION!
Electrical/mechanical hazard – risk of damage to the device. Before installing the device in a rack,
make sure of the following:
• When installing the device in a closed or multi-device rack, be aware that the operating ambient
temperature of the rack may be higher than the ambient temperature of the room. Make sure the
rack is installed in a suitable environment that can withstand the maximum ambient temperature
generated by the rack.
• Make sure each device in the rack is separated by at least one rack-unit of space, or 44 mm (1.75
in), to promote convectional airflow. Forced airflow is not required. However, any increase in airflow
will result in a reduction of ambient temperature and improve the long-term reliability of all equipment
mounted in the rack space.
• Do not exceed the maximum number of devices or weight restrictions specified by the rack
manufacturer.
• Do not overload the supply circuit. Refer to the over-current protection and power supply ratings
specified by the rack manufacturer.
• Make sure the rack and all devices have a proper ground-to-Earth connection. Pay particular
attention to power supply connections other than direct connections to the branch circuit (e.g. power
strips).
To secure the device to a standard 48 cm (19 in) rack, do the following:
1. Make sure the rack mount adapters are installed on the correct side of the chassis.
• To make the modules and ports accessible, install the rack mount adapters at the rear of the chassis
• To make the management ports and LEDs accessible, install the rack mount adapters at the front of the
chassis
NOTE
The chassis features multiple mounting holes, allowing the rack mount adapters to be installed up
to 25 mm (1 in) from the face of the device.

Section 2.2
Connecting Power
The RX1500 supports dual redundant high AC, high DC and/or low DC power supplies that can be installed in
any combination. The use of two power modules is recommended to provide redundancy and load balancing.
The RX1500 can be equipped with either a screw-type or pluggable terminal block. The screw-type terminal
block is installed using Philips screws and compression plates, allowing either bare wire connections or crimped
terminal lugs. Use #6 size ring lugs for secure, reliable connections under severe shock or vibration.
IMPORTANT!
• In a high AC/DC and low DC (24/48 V) power supply arrangement, the placement of the AC and DC
power supplies is not slot-dependent. Either power module slot can be used for AC or DC power.

RUGGEDCOM RX1500
Installation Guide
Chapter 2
Installing the Device
Installing/Removing Power Supplies 9
• For maximum redundancy in a dual power supply configuration, use two independent power
sources.
• Use only #16 gage copper wiring when connecting terminal blocks.
• The maximum wire length between the terminal block and power source must not exceed 6 m (20 ft)
for 24 V power supplies or 18 m (60 ft) for 48 V power supplies.
• For 125/230 VAC rated equipment, an appropriately rated AC circuit breaker must be installed.
• For 125/250 VDC rated equipment, an appropriately rated DC circuit breaker must be installed.
• It is recommended to provide a separate 20 A circuit breaker for each power supply module.
• Equipment must be installed according to applicable local wiring codes and standards.
The following sections describe how to connect power to the device:
•Section 2.2.1, “Installing/Removing Power Supplies”

Section 2.3
Connecting the Failsafe Alarm Relay
The failsafe relay can be configured to latch based on alarm conditions. The NO (Normally Open) contact is
closed when the unit is powered and there are no active alarms. If the device is not powered or if an active alarm
is configured, the relay opens the NO contact and closes the NC (Normally Closed) contact.
NOTE
Control of the failsafe relay output is configurable through ROX II . One common application for this
relay is to signal an alarm if a power failure occurs. For more information, refer to the ROX II User
Guide for the RX1500.
The following shows the proper relay connections.
