Power and Ground Connection

3.5.1

General

All Consolettes should have a separate AC power circuit with proper current and voltage for
Consolette operation. Refer to the specifications section in the front of this manual for AC
requirements of each model. The power lines should be installed in accordance with local electrical
codes. A substantial earth ground must be provided in a straight line close to the ground terminal
provided on the Consolette. DO NOT consider an electrical output box as a substantial earth ground.
See "Lightning and Surge Suppression," on page xiii

The AC power line leading to the selected site for the Consolette may be installed prior to installation
of the Consolette itself.
NOTE: Positive ground DC is not supported.
3.5.2

AC Power Input

The Consolette power supply is auto-switching and supports a nominal 110-220VAC input, 50-60Hz
via a standard IEC 320 power inlet.
1. Install the Consolette as described in section
1.
2. The Consolette power supply is auto-switching. Setting of a switch for 110VAC or 220VAC
operation is not required.
3. Connect the female plug of the AC line cord supplied with the Consolette to the AC input
power connector on the rear panel of the Consolette. See
3-3.
4. Connect the ground terminal on the Consolette in as straight a line as possible to a
substantial earth ground located as close as possible to the Consolette ground terminal.
5. Make certain the AC power source is of the proper current and voltage rating for the
Consolette. Refer to the specifications section in the front of this manual for the AC
requirement of each model. Then connect the male plug of the AC line cord to the AC power
source.
6. The power-on LED on the front of the Consolette will be lit green when the unit is powered
from an AC source.
September 9, 2011
Even if a three-wire grounding AC power source is
available, the radio equipment must be grounded
separately to prevent electrical shock hazards and provide
lightning protection.
This equipment is designed to permit the connection of the
earthed conductor of the D.C. supply circuit to the earthing
conductor at the equipment.
