Any precautions on installing HI 1746WS modules in my SLC500 rack?

I would like to put three Hardy modules in an existing SLC500 rack. I have three open slots. Will this cause any problems and what should I look for when preparing for this?

Precautions you should take when installing your HI 1746WS module in a SLC500 rack are:

1. Do not install the HI 1746WS next to high voltage modules such as analog input or analog output.

2. Make sure you have 32 words of input and output memory available per card.
