Installation
Before installing the
DXE-PS-2B-P
Relay Unit with control cable onto the tower, connection of the
entire length of four (4) conductor control line between the
EC-PS2
Control Console and the
PS2B
Relay Unit for testing purposes is recommended.
Following installation of the two equal length coaxial cables (
PS2B
Relay Unit to antennas) on the
Relay Unit during testing take continuity measurements to insure the system is functioning
properly. Any trouble found during testing may be addressed before the
EC-PS2
and
PS2B
are
installed into their operating positions.
Open the
EC-PS2
control console by removing the four (two per side) Phillips head screws to
remove the cover.
Push the end of the cable through the control wire feed through grommet on the rear of the unit.
Connections for the wire are made on the green header.
Loosen each terminal screw until it is near flush with the top
of the connector block as shown to the right.
Strip approximately 1/4" insulation from the four conductor
wire ends as shown to the right.
Connect each wire to a terminal by sliding the wire completely into the wire connection hole. Using
a small flat blade screwdriver, tighten the associated screw until the wire is firmly gripped in place
as shown below. The four-conductor control cable goes between the
PS-2B
Relay Unit and the
EC-
PS
Control Console. Either "G" is ground. Terminals G, 1, 2 and 3 are used.
COM-CW4
four
conductor cable is available by the foot for your installation requirements.
Take caution to ensure just the wire is clamped in place, not the wire's insulation which would cause
an open or intermittent connection. Do not over tighten the screw so much that the wire is cut
instead of being firmly gripped. Use the included Ty-Wrap on the inside of the unit to hold the cable
from pulling outward as shown above. Your color code may vary.
Input power should be +12 Vdc, well filtered at 2 amps (fused) minimum. A 2.1 mm power cord is
supplied with unit. The wire with the white stripes is the +12 Vdc.
