instrumentationpanel.
Install it in a location where people cannot touch
theterminalscarelessly.
 •TomaketheGP10/GP20complywiththe
relevantstandard,supportthepartsofthedevice
other than the front-panel control area with an
instrumentationpanelorthelike,andinstallitina
locationwherepeoplecannottouchtheterminals
carelessly or in a panel.
 •InstalltheGX60/GMunitinapanelwithadoor.
