Installation
PHYSICAL INSTALLATION
MOUNTING THE AC7
the standoffs should be secured using #6 hardware to provide maximum physical strength. Leave sufficient space around the AC7
for serial data link and power wiring.
CONNECTING POWER SUPPLIES
for a separate +5-Volt supply. Using the onboard regulator defeats the optical isolation feature, but provides satisfactory operation
in many applications. To use the 5-Volt regulator, install jumpers "E" and "F" and Do Not Connect anything to the 5-Volt input
terminals.
OPTICAL ISOLATION ON AC7
are required. In this mode, AC7 requires 200 milliamps at +5 Volts and 50 milliamps at +12 and -12 Volts. Jumpers "E" and "F"
MUST be removed if a separate +5 Volt power supply is connected.
The following equipment should be available during installation of the AC7:
• Medium sized, flat-blade screw driver
• Wire stripper
• 25-Watt soldering iron
• 18 guage wire for power connections
• 22 guage twisted-pair RS-422 cable for data link
The AC7 adapter card can be mounted in any position on any flat surface. The adapter card is supplied with 3/4” standoffs. All
Single Power Supply - No Optical Isolation
The 5-Volt power required by AC7 can be derived from the +12-Volt power input by an onboard regulator, eliminating the need
In this mode, AC7 requires +12 Volts at 200 milliamps and -12 Volts at 50 milliamps.
A 5V power supply can be used to provide optical isolation on the AC7 by connecting to the 5V terminals.
Two Power Supplies - Provides Optical Isolation
To take advantage of the Optical Isolation feature of the AC7, separate power supplies for +5 Volts and for +12 and -12 Volts
