I searched for this already (here and on other sites) and found nothing. The zapper, used in the quest Material Support, has the usual short range and a delay before taking effect (timer bar). The stipulations require that you not be in combat. Once you use the device, the haywire spider immediately aggros and moves to attack. Problem is, by the time the zapper is supposed to activate, the message "no targets in range" comes up because by then I am "in combat." If I move to keep distance the zapper is interrupted. There does not seem to be any way around the spider aggro'ing me, nor a way to avoid combat prior to the device having an effect. This has to have been done many times; what is the solution?
