Installing the plug-in cards
Optional plug-in cards

located on the transmitter motherboard and can be accessed after removing the front housing cover.
*The ‘Number’ column indicates the maximum number of plug-in cards of the same type that can be used.
Loss of Ex Approval!
Loss of Ex Approval due to retrofitting of plug-in cards on devices for use in potentially explosive atmospheres.
• Devices for use in potentially explosive atmospheres may not be retrofitted with plug-in cards.
• If devices are to be used in potentially explosive atmospheres, the required plug-in cards must be specified when the
order is placed.
