If possible, you should try to run your S9s on 240V. You should be able to run all 4 S9s on one 30A 240V circuit. Connect them to the circuit via a PDU like this one: https://www.amazon.com/gp/product/B0007YG85A
Ambient intake air temps can safely be up to around 100F. I like to keep them below 95F.
I also like to keep Chip temps below 85C, preferably below 78C.
The most important part of Antminer ventilation design is air replacement (not AC). You need to have about the same amount of fresh air (filtered preferably) going into the front of your miners as is being exhausted out. A good ballpark rule of thumb is 200CFM per Antminer in AND out. You will need intake fans AND exhaust fans.
You can read-up on the factory specs and recommended ambient/PCB/chip temps in the various Antminer user guides available at https://service.bitmain.com/support/download .
Power-cycling your Antminers will not hurt them. If you have an older Bitmain firmware version that allows SSH access, you will preferably want to SSH (Putty) into them (IP address) first and do the following prior to pulling the plug.
(Default SSH login name is: "root" and password is: "admin" (both no quotes).)
type "poweroff" (no quotes), and press Enter.
Close the SSH session.
Wait 5 minutes while the miner cools down, and then physically unplug the power supply to your S9.
To restart, simply plug the power supply back in and let your miner boot up. Takes about 5 minutes before it's mining again.
If you don't have SSH access, don't sweat it, just reboot the miner, and unplug the network cable. Usually by the time it has rebooted and completed the fan test, it has cooled down enough to unplug.
If you don't want to use either of the above methods, just pull/disconnect the power. It's not ideal, but it will do the job.
I prefer to use Slushpool. Helpful instructions here:

Good luck!!
Thats a twist lock with the correct c13 end for a computer / bitmain power supply yeah. 14 gauge is nice too... thats what I use from my PDU's to each machine. The 3 prong wont fit the outlet in your picture though, you'll need to rewire it to something like this:
https://www.amazon.com/Leviton-2620-Receptacle-Industrial-Grounding/dp/B00002NAT9/ref=pd_lpo_vtph_23_bs_t_1?_encoding=UTF8&psc=1&refRID=AB56ZCHD7BGJW6QN1DGH
Should be a really simple job for any electrician... just need a box, the outlet and a few minutes.
If you switch out the outlet you could also run one of these:
https://www.ebay.com/itm/Tripp-Lite-PDU-Basic-208V-240V-30A-20-Outlet-15-ft-Cord-PDU1230/112826455467?epid=1837218544&hash=item1a44fb15ab:g:Nz4AAOSw2cNakT4K
which will let you run the number of miners that outlet is capable of (30 amp). 30 amps * 80% = 24 usable amps. Each miner runs around 6amps on 240, so 4 s9's safely from the one outlet (through a PDU of course).
You might have to make your own cord. Thats what I did with that kind of receptacle. You just need this plug and this cord or any other 240v cord that terminates in a c13. That cord will support one miner to be safe since its rated for 15A.
Anyone mining with 110v with luck? or this transformer? https://www.amazon.com/gp/product/B00ER52DMW/ref=ox_sc_act_title_1?smid=ALEWIQ2F9CQDR&psc=1
Holly Shit... Looks like I'm not alone.
My meter model: https://www.amazon.com/gp/product/B071LB8MPZ/
Plugs:
https://en.wikipedia.org/wiki/NEMA_connector#/media/File:NEMA_simplified_pins.svg
See the wikipedia page on it. Your dryer might be listed there. I had electrician install a L6-30 receptacle and a 240(220) / 30 amp breaker.
Then I got a unit like this:
https://www.amazon.com/gp/product/B0053YIUPK/ref=oh_aui_detailpage_o02_s00?ie=UTF8&psc=1
you can do a 15 amp, 20 amp version though also as its cheaper, just stay 240v
Does this wire look like it could work for the rig? https://www.amazon.com/NEMA-L6-30P-C13-Power-Cord/dp/B004WODG6A
What's the biggest issue if I use this cord?
I use this one, pretty decent. I can handle 3 to 4 antminers (depending on model). Tripp Lite Basic PDU, 30A, 20 Outlets (16 C13 & 4 C19), 200/208/240V, L6-30P Input, 15 ft. Cord, 1U Rack-Mount Power (PDU1230) https://www.amazon.com/dp/B0007YG85A?ref=yo_pop_ma_swf
Oh I didn't know the L3+ only uses 800W compared to the S9 which uses 1200W
Does that mean I can purchase the EVGA 850W version for the L3+
https://www.amazon.com/dp/B018JYHGOQ/ref=twister_B01AHMAHXK?_encoding=UTF8&psc=1
So please someone correct me if I'm wrong. I believe you need a L6-30r recepticle with a L6-30p pdu and use c13 to c14 cables preferably 14awg.
