Operate Explosive Atmosphere
operate system presence flammable gases fumes. Operation electrical system such environment constitutes definite safety hazard.
Keep Away from Live Circuits
Operating personnel must remove product covers. Component replacement internal adjustments must made qualified maintenance personnel. replace components with power cable connected. Under certain conditions, dangerous voltages exist even with power cable removed. avoid injuries, always disconnect power discharge circuits before touching them.
Service Adjust Alone
attempt internal service adjustment unless another person, capable rendering first resuscitation, present.
Substitute Parts Modify System
Because danger introducing additional hazards, install substitute parts perform unauthorized modification product. Return product VMIC service repair ensure that safety features maintained.

Unpacking Procedures
CAUTION: Some components assembled VMIC's products sensitive electrostatic discharge damage occur boards that subjected high-energy electrostatic field. When board placed bench configuring, etc., suggested that conductive material should inserted under board provide conductive shunt. Unused boards should stored same protective boxes which they were shipped. Upon receipt, precautions found shipping container should observed. items should carefully unpacked thoroughly inspected damage that might have occurred during shipment. board(s) should checked broken components, damaged printed circuit board(s), heat damage, other visible contamination. claims arising from shipping damage should filed with carrier complete report sent VMIC together with request advice concerning disposition damaged item(s).
Physical Installation
NOTE: install remove board while power applied. De-energize equipment insert board into appropriate slot chassis. While ensuring that board properly aligned oriented supporting board guides, slide board smoothly forward against mating connector until firmly seated.
