When you enable iCloud Photo Library on your device, it does not delete your pics. All of your pics will be synced or copied to iCloud Photo Library. The photos on your device will remain. That has been my experience and I've experimented with enabled and disabling iCloud Photo Library on several occasions. Having said that, make sure you have a copy of all of your pics just in case. Copy them onto your computer or to Dropbox, OneDrive, box or any of the other cloud services. You can always download them back to your device if necessary.
