AD8420: +/-1V differential input voltage a rule or suggestion?

I am using an AD8420 in a current-sensing application.The differential input range during operation won't exceed +/-1V, but when the device is in standby mode, a relay opens, and the inputs are exposed to greater differential input voltages.

 

Is the +/-1V limit on the datasheet a design guideline, or a limit to prevent device damage?  Will I need to put voltage steering diodes on these inputs?
