Default Microphone T-powering question

I'm planning to use the attached diagram to put t-power in a channel of an XLR patchbay using a 12v battery pack for an old Microtech Gefell PM860 mic. MY question is to make sure I'm not going to mess up a modern preamp running 12v across pins 2 and 3 with nothing to ground.
