Description
The RV-07B is a 19" rack which can hold up to 16 Westermo TR-36B modems as well
as two PS-20 power supplies. The modem is designed to harsh industrial standards in
applications where a number of modems are required in the same location. The rack has
passed extensive approvals testing by both Westermo and external test houses, showing
the rack can operate in environments with a high level of electromagnetic interference.
Using the RV-07B and TR-36B allows a number of modems to be connected to a backplane thus eliminating unnecessary wiring and also saving space.
The modems slide into the chassis from the front and connect to the backplane that
provides all the connectors for the RS-422/485, RS-232, PSTN and Leased Line interfaces.
The RV-07B can be fully powered by either one or two Westermo PS-20 power supplies.
With two power supplies, redundant supply is possible. In case of a power failure, the
second power supply activates and an alarm signal can be set up through the built-in fault
relay.
The RV-07B rack is designed for use with the Westermo TR-36B modem, which is an analogue V.34 PSTN and Leased Line modem supporting modulation data rates up to 33.6
Kbit/s. For more information, please refer to the TR-36B documentation.

To minimise the risk of interference, a shielded cable is recommended when the cable is located inside 3 m
boundary to the rails and connected to this port.
The cable shield should be properly connected (360°) to an earthing point within 1 m from this port. This earth-
ing point should have a low impedance connection to the conductive enclosure of the apparatus cabinet, or
similar, where the unit is built-in. This conductive enclosure should be connected to the earthing system of an
installation and may be directly connected to the protective earth.

Description
PS-20 – Power card
The PS-20 is a 90-254 VAC power supply designed to power the RV-07 and the RV-07B
racks. The power supply is designed to harsh industrial standards in applications where
a number of modems are required in the same location. The rack has passed extensive
approvals testing by both Westermo and external test houses, showing the rack can
operate in environments with a high level of electromagnetic interference.
This unit has one separate protective earthing terminal (marked with “symbol”), while
the unit is provided with two mains supply connectors. The grounding terminal of these
mains supply connectors is a functional earthing point only Prevent access to hazardous
voltages by disconnecting the unit from AC/DC mains supplies and all other electrical
connections. A protective earthing conductor should be connected to the protective
earthing terminal and have a cross-sectional area of at least 1.5 mm
internal electronics from electrostatic discharges (ESD) by discharging your body to a
grounding point (e.g. use of
wrist strap).
Mounting
This unit should be horizontally mounted with screws
in the holes located in the
left and right hand brackets on
the unit.
2
. Prevent damage to
Connect the protective earthing conductor to the protective earthing terminal,
before connection of any AC/DC mains supply or other electrical connections.
As this unit uses convection cooling, it is important to avoid obstructions that prevent
normal vertical airflow through the unit. For this reason a clearance of 1U below and
2U above the unit is recommended. These clearance distances should be increased if
heat from another unit is likely to cause an undesirable rise in temperature. Under no
circumstances should the air temperature around the unit exceed 15 degrees C above
the operating temperature of any modem installed in it. The unit should be installed in a
cabinet that has suitable fans and filters so that good airflow is maintained without the
ingress of dirt or dust.
Removal
Disconnect all AC/DC mains supplies and other electrical connections before the removal of protective earthing conductor from the protective earthing terminal.
Note:
• Always add modems from one end in the rack.
• To ensure proper galvanic connection between front panels, do not leave empty
slots between modems.
