5.0 STEP-BY-STEP INSTALLATION
In most cases, the steps given here are sufficient to install the trans-
ceiver. Refer to "INSTALLATION PLANNING" on Page 8 for addi-
tional details.
1. Mount the transceiver. Attach the mounting brackets to the bottom
of the transceiver case (if not already attached), using the four 6-32
x 1/4 inch (6 mm) screws supplied. Mounting bracket dimensions
are shown in Figure 7 on page 9. Secure the brackets to a flat,
grounded surface. (If a grounded surface is not available, run a
separate ground wire to the transceiver—see "Grounding
Considerations" on Page 13.)
2. Install the antenna and feedline. The antenna used with the radio
must be designed to operate in the radio's frequency band, and be
mounted in a location providing a clear path to the associated sta-
tion(s). At Remote sites, aim directional antennas toward the master
unit. Use low-loss coaxial feedline, and keep the feedline as short as
possible.
3. Connect the data equipment. Make the connection using Serial
protocols (RS-232/RS-485).
Connect a serial device to COM2 on the front panel. The radio is
hardwired as a DCE device. Use a straight-through cable for most
applications.
4. Connect primary power. Input power must be within the range
printed above the power connector, and capable of providing at least
2.5 A. A power connector with screw-terminals is provided with the
unit (see Figure 11 on page 12). Strip the wire leads to 1/4 inch
(6 mm) and insert them into the wire ports. Be sure to observe
proper polarity. Tighten the binding screws securely.
The unit is designed for use with negative-ground sys-
CAUTION
tems only. The power supply should be equipped with
POSSIBLE
overload protection (NEC Class 2 rating), to protect

DAMAGE
against a short circuit between its output terminals
and the radio's power connector.
NOTE: To comply with IEC61850-3, paragraph 5.7.1.2, surge
suppression must be used across the power supply for Class 3
and 4 severity levels as defined by IEC 61000-4-5 Annex A.
