2.6.3 Panel Mounting

During panel or DIN mounting of all devices keep them free of debris and
avoiding overheating:
• Do not remove protective debris strip until after the module and
all other equipment near the module is mounted and the wiring is
complete.
• Once wiring is complete, and the module is free of debris,
carefully remove protective strip.
• Failure to remove strip before operating can cause overheating.
Mount the module to a panel using two screws per module. Use M4 or #8
panhead screws. Mounting screws are required on every module.
