Sanden AC compressor install

So I have been rebuilding my 73 cuda and have installed a new sanden type ac compressor and appropriate brackets. The motor has been rebuilt and I want to start it without an refrigerant in the AC system.
At this point I do not have the hoses etc to complete the AC system but wanted to mount everything so I can get the fan belts in to run the alternate etc.
Will I harm the compressor spinning it without refrigerant, the electrical will not be hocked up so no change of turning it on by accident.
Please advise

thanks to all
