AC AND EARTH GROUND WIRING
CAUTION!
DO NOT CONNECT BASE MODULE JACK J1 UNTIL
ALL TRANSFORMER WIRING IS COMPLETE.
AC Power Wiring
(using plug-mounted transformer)
Run an 18AWG (or larger) 2-conductor cable out the hole in the
cabinet bottom to the plug-mount transformer (or the transformer
enclosure).
The Base Module J1 screw terminal block pins 1 and 2 (labeled AC
16.5V) provides the connections for the 16.5VAC, 50 VA input from
the plug-mount transformer. Connect the power wires into the J1-1
and 2 terminals (polarity is not important).
WARNING!
UNLESS OTHERWISE INSTRUCTED,
DO NOT PLUG
THE TRANSFORMER INTO THE AC OUTLET UNTIL
ALL WIRING IS COMPLETE.
Connect the wires to the transformer terminals.
When ready to plug the transformer into the AC outlet, remove the
outlet cover plate screw and place it through the transformer case tab.
Plug the transformer into the bottom outlet, insert the screw through
the transformer and cover plate, then tighten. This secures the
transformer, preventing accidental disconnection.
AC Power Wiring
(using open frame transformer)
The open frame transformer comes pre-installed inside the chassis
with a fuse block and a DITEK 120 VAC surge protector.
AC power coming inside the chassis connects at the fuse block as
shown in Figure 3. You can bring AC power to the fuse block via
either the AC power cord (included), or wire it directly from a 120
VAC power line.
The Base Module J1 screw terminal block pins 1 and 2 (labeled AC
16.5V) provides the connections for the 16.0VAC, 43 VA input from
the open frame transformer. Connect the power wires from the
transformer to the J1-1 and 2 terminals (polarity is not important).
WARNING!
UNLESS OTHERWISE INSTRUCTED,
DO NOT PLUG
THE TRANSFORMER CORD INTO THE AC OUTLET
OR TURN THE CIRCUIT BREAKER “ON” UNTIL
ALL WIRING IS COMPLETE.
SYSTEM GROUNDING
NOTE: All Advantage plus modules isolate earth ground
from signal ground. This is done to meet UL
requirements, and also allows all the interconnect
modules to share the same signal ground when there
may be a large difference in potential between earth
grounds. Earth ground must remain isolated from
signal ground.
Earth Ground Wiring
WARNING!
IF USING THE 115 VAC, 43 VA OPEN FRAME
TRANSFORMER
DO NOT CONNECT AN EXTERNAL
EARTH GROUND TO THE CHASSIS EARTH GROUND
STUD. THE ELECTRICAL GROUND AT THE OPEN
FRAME TRANSFORMER ACTS AS THE EARTH
GROUND IN THIS CHASSIS.
NOTE: Always install AC and Earth Ground wiring per Article
250 of the National Electrical Code.
