Something isn't jibing here...see page 3:
Instructions for Operation
• Please consult with a licensed electrician prior to installation of the Helios® 9.
• DO NOT install this controller yourself if you DO NOT fully understand these instructions. High
voltage is dangerous!
• Plug 30 Amp pig tail cord set into a confirmed 30 Amp AC power outlet or connect the
incoming 240 Volt power to the 3 screws under the protective back cover.
Black/hot leg (left
screw), neutral (center screw) & red/hot leg (right screw).
• Securely mount your Helios® 9, using the hardware included, near your enclosure and away
from any spray/water/mist, etc.
• Verify that all your wiring connections are tight and that no loose wires are exposed.
• Use a test meter to verify that 240 Volt power is coming out of the ‘240 volt power output’
outlets before plugging your ballast into the Helios® 9.
• Then, plug your ballasts into the outlets on the right and left side of the controller.
• Plug the relay trigger cord set into the Apollo® 8 120 Volt wall timer (included). Set your timing
pattern (i.e. 12 hours ON and 12 hours OFF). Then, adjust the timer to the current time of day
• Make sure that all wires and cables have been properly secured.
• When the relay is activated via ‘relay trigger cord sets’ you will hear a loud “Clunk” sound.
• Your Helios® 9 will now control your lights at the desired settings until the power is defeated.
• Caution: Lamps are hot and should be allowed to cool completely before handling.
ONLY FOR USE WITH 240 VOLT BALLASTS
See bolded above. This conflicts with the plug type listed on that same page 3 in the lower right corner - NEMA 14-30r and 14-30p.
So, I based my response on the type of plug listed rather than the bolded above. I'm not really sure what to say at this point. Having been a commercial electrician for many years I know that EVERYTHING is grounded...I repeat...EVERYTHING. Neutral is not exactly the same as ground so I'm not sure what I'm missing here.
