Step 4. Attach line disconnects to pig tail cable.
a. Verify circuit breaker is in "off" position before installing line disconnect(s).
b. Connect line disconnect(s) to end of AC tails (2/0 or 8/5). (Line disconnects should be
easily accessible in case emergency requires shutting off power to system.)
Step 5. Attach Bucking Transformer (if required).
If house AC service is below 100 VAC or above 240 VAC (Europe, Japan and Australia), it
may be necessary to connect Bucking Transformer between pig tails and lighting system
ACS or modular racks to reduce or raise voltage to desired level. (A standard Bucking
Transformer accepts only Cam-Lok style connectors.)
Step 6. Run additional AC feeder cables to rack location(s).
Connect additional lengths of 2/0 or 8/5 feeder cable to extend power to location of ACS
rack(s), modular rack(s), or conventional dimmer area.
Step 7. Make sure that Cam-Lok connections are tightly secured.
High voltage is present, careful preparation should be taken.
Step 8. Connect ACS, Modular or Mini-ACS Racks to feeder cables.
Connect cables securely to proper input connectors.
Step 9. Connect DMX200 unit to ACS rack.
a. Install DMX200 interface on rack or other suitable enclosure.
b. Connect DMX200 translator Y cable from DMX200 Power In/Data Out to ACS rack
Power Out and Data In.
c. Connect DMX input cables to five-pin XLR, DMX IN ports as needed. One connector
for luminaire addresses 1 through 497 and one connector for addresses 501 through 999.
Note: If only one universe of DMX512 is required, ensure that the XLR connector is connected to
DMX512 input number one (on left).
