RISK OF UNINTENDED EQUIPMENT OPERATION
Failure to follow this instruction can result in death, serious injury or equipment damage.
Do not add or remove an expansion module to or from the system before first removing all
power. Adding or removing an expansion module while under power can cause damage to
the module and the system resulting in unexpected operation of inputs and outputs.
Depending on the I/O configuration, unintended equipment operation can occur.
•
All expansion modules such as EX modules should be installed in the HTB before installing an
island on a DIN rail. The island should be removed from a DIN rail before disassembling the dif-
ferent modules.
Keep adequate spacing around the island for proper ventilation and to maintain an ambient
temperature between 0°C and 55°C.
Overheating of the HTB and/or the I/O expansion modules can result in unexpected
operation of inputs and outputs. Depending on the I/O configuration, unintended equiment
operation can occur.
Do not place heat generating devices such as transformers and supply blocks under the
island.
Heat generating devices in proximity of the HTB and I/O expansion modules could result in
elevated temperatures and overheating, and can result in unexpected operation of inputs
and outputs. Depending on the I/O configuration, unintended equipment operation can
occur.
