Grounding
Connect all chassis grounding terminals labeled GND on the rear panel to a
rack frame ground or main station ground for proper safety and performance.
Use 14 AWG (2 mm2) or larger wire, less than 3 m (10 ft) in length, for this
connection. All ground terminals connect directly to the internal chassis
ground of the SEL-2902.
Applications
SEL-2020, SEL-2030, SEL-2032,
and SEL-3530 Retrofit Application
The adapter panel with the adjustable-depth rack-mount option can be
configured between 7 and 11 inches in depth to match an existing SEL-2020,
SEL-2030, SEL-2032, or SEL-3530 installation. Matching the device depth allows
existing communications cables with DB-9 connectors to be retained. Use an
SEL-CA605 cable or equivalent shielded Ethernet patch cable to con-nect the
adapter panel RJ45 port to the ports on an SEL-3350, as shown in Figure 4, or
an SEL-3355 that is using the optional SEL-3390S8 Serial Adapter Cards.
SEL-3350 and SEL-3355 and Secure
Mounting of Transceivers
Securely mount the adapter panel with the surface-mount ordering option to a
solid surface, a 19 in rack-mount panel, or DIN rail by using the optional
DIN-rail mounting kit (915900639). Connect serial transceivers with a DB-9
male connector to the DB-9 port. An SEL-CA605 or equivalent shielded Ethernet
patch cable can be used to connect the RJ45 port to the ports on the SEL-3350
or SEL-3355.
Installation
Unit Location and Placement
For trouble-free operation, use the following guidelines to properly install
the SEL-2902.
Mount the SEL-2902 with the SEL-3300 series device in a sheltered indoor
environment (a building or an enclosed cabinet) that does not exceed the
temperature and humidity ratings for the unit (see Specifications on page 10).
The unit is rated as Installation/Overvoltage Category II (at <5 km altitude)
and Pollution Degree 2. These ratings allow you to mount the unit indoors or
in an outdoor (extended) enclosure where the unit is protected from direct
sunlight, precipitation, and full wind pressure but temperature and humidity
are not controlled. To satisfy safety requirements, install the unit in a
suit-able fire/electrical/mechanical enclosure.
To ensure best EMI and EMC performance, the SEL-CA605 cable or equivalent
shielded Ethernet patch cable that connects the SEL-3300 series device to the
SEL-2902 RJ45 port should not exceed 2 meters
(6.6 feet) in length.
Mounting Bracket Adjustment
The adjustable-depth mounting option ships by default at 8 in, as shown in
Figure 5. Adjust the depth in 1 in incre-ments from a minimum depth of 7 in to
a maximum of 11 in, as shown in Figure 6.
To adjust the depth, remove four screws from the side and eight screws from
the bottom, as shown in Figure 7. Move the adapter panel to the desired depth,
as shown in Figure 8. Reinstall the screws, as shown in Figure 9. Torque the
screws to 12 in-lb.
Adjusting Rack-Mount Depth
Surface Mounting
To mount the adapter panel with the surface-mount option, use the dimensions shown in Figure 14 and drill holes no larger than 3/16 in (5 mm).
DIN-Rail Mounting
To use the optional DIN-rail mounting kit (915900639), snap the two DIN-rail
clips onto your DIN rail. Align the DIN-rail clips with the center of the
adapter panel mounting ears, as shown in Figure 11. Thread the included #8
plastic screw through the hole and into the DIN-rail clip. Torque the screw to
12 in-lb after it is fully seated.
Cable Management
Each SEL-2902 that is configured with the adjustable-depth bracket is shipped
with accessory mounting ears and hard-ware, as shown in Figure 12. The
mounting ears can only be installed (torque screws to 12 in-lb) after the
adapter panel has been installed. Use third-party cable management brackets
compatible with 2U, 19 in rack-mount holes.
