Let’s take an example. Here is a camcorder. The camcorder is packed in a small box (inner packaging), and the batteries are packed in a separate small box (another inner packaging). These two small boxes (inner packagings) are thence packed in one outer packaging (PI 966 or PI 969). This is the definition of “packed with equipment”. You may overpack as many outer packagings as needed. Furthermore, you may include other dangerous goods or non-dangerous goods into this overpack as long as they do not react dangerously with each other.
