Do not place heat generating devices such as transformers and supply blocks under the island.
Heat generating devices in proximity of 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.
Do not exceed the 450mA current limit for HTB and its expansion modules. Exceeding these limits can
result in interruption of power to the I/O. Depending on I/O configuration, unintended equipment operation
may result.
If outputs should fail, outputs may remain on or off. Where personnel and or equipment hazards exist, use
an appropriate hard-wired safety system.
When the power supply voltage is outside of the specified voltage range, one or more outputs may not
operate as expected. Use an appropriate externally-wired safety system to control and monitor the system
voltage and ensure the specified voltage range is maintained.
Turn power off before installing, removing, wiring, or maintaining.
This product is not intended for use in safety critical machine functions. Where personnel and or
equipment hazards exist, use appropriate hard-wired safety interlocks.
Do not disassemble, repair, or modify the modules.
This controller is designed for use with in an enclosure.
Install the modules according to the installation instructions on page 3-2.
Use the sensor power supply only for supplying power to sensors connected to the module.
Use an IEC60127-approved fuse on the power line and output circuit to meet voltage and current
requirements.
