1.3.3 The unit is sensitive to ESDDescriptionESD (electrostatic discharge) is the transfer of electrical static charge between twobodies at different potentials, either through direct contact or through an inducedelectrical field. When handling parts or their containers, personnel not groundedmay potentially transfer high static charges. This discharge may destroy sensitiveelectronics.Safe handlingNoteActionWrist straps must be tested frequently to ensurethat they are not damaged and are operating cor-rectly.Use a wrist strap. The wrist strapbutton is located inside the control-ler.1The mat must be grounded through a current-limit-ing resistor.Use an ESD protective floor mat.2The mat should provide a controlled discharge ofstatic voltages and must be grounded.Use a dissipative table mat.332 Product manual - IRC5 Panel Mounted Controller3HAC047137-001 Revision: J© Copyright 2007-2018 ABB.
