Oh, ok.
Something like..."unplugging" it. You have to unplug it, then destroy the poles on the other side. But then, you'd have to stay on that side.
However, the Yeerks are going to install biofilters in the doors to the Kelp-Gair facility, and INSIDE are the Yeerk pool and Temporal portal. There are also 4 Blue-Band guards at each door. So, as you can imagine, it'll be a little difficult to enter.
