2 Retrofitting of modules
General safety information
WARNING!
Danger due to hazardous electrical voltage
Incorrect handling may result in personal injury.
 Only qualified personnel are permitted to open the device.
 Before opening, take the device out of operation and disconnect all poles from the power supply.
CAUTION!
Danger due to incorrect handling
Incorrect handling may result in damage to the device or malfunctions.
 Only qualified personnel are permitted to carry out module retrofits.
 The country-specific requirements regarding changes to an electrical device must be observed.
CAUTION!
Danger due to electrostatic discharge
Device and modules may be damaged by electrostatic discharge.
 The modules may only be retrofitted at a grounded workstation and in compliance with the relevant
safety measures.
WARNING!
Danger due to hazardous electrical voltage
If openings in the housing are not closed by inserting the right module, the device no longer complies
with protection type IP20. The device must not be put into operation!
 Only open the housing at the slots where modules are attached.
 Only remove the tab on the cover (housing opening for the connection terminal of the functional
ground) if an Ethernet or PROFINET module with threaded block (FE connection) is to be plugged in.
WARNING!
Danger due to hazardous electrical voltage
For devices in the formats 108H, 108Q, and 104: Removing the separators between the slots shortens
the clearances and creepage distances (reduces insulation).
 Do not use any modules that can carry mains voltage at the applicable slots (relay, solid state relay).
CAUTION!
Danger of material damage due to modifications to the device
The device's function may change unintentionally due to errors during retrofitting or replacing modules.
 A functional test must be performed in a test environment before starting up the device in a system.
Overview of modules
The following modules are available for retrofitting optional inputs and outputs, relays, and interfaces.
Use depends on the format of the device (options 1 to 6, see Table).
Each module can be identified using the part no. (TN) on the packaging.
