Hi jjihonor and welcome to Beoworld.
You cannot connect the Beogram 4002 directly to your Beomaster 4500 due to a lack of RIAA (pre-amp) in this model of turntable. You can however connect it using an external RIAA fitted between the Beogram and your Beomaster. The problem with doing this though is you will lose the remote control capability and a couple of DIN/RCA (phono) adaptor leads are usually needed. Worth doing though as the 4002 is amongst the most highly rated of all the Beograms.
Beograms with the RIAA fitted that will plug straight into your Beomaster and will work with remote control are the following:-
Beogram 4500, 3500, 6500 & 7000. There is also the tangential beogram 6000 quad which has the fitted RIAA but I'm unsure whether this is compatible as far as remote control works - I'm sure someone here will know.
The 4500 is obviously the best cosmetic match as it was designed to be used with your existing system.
