Precautions
Observe these precautions when installing the I/O module to reduce the risk of injury
or equipment damage:
l Power for the I/O module is intended to be supplied by a NRTL listed power
supplywith a 24VDC output rated at 750mA or more, a maximum short
circuit current rating of less than 8A, a maximum power rating of less than
100VA, and marked Class 2 or Limited Power source (LPS). Any other
voltage creates a risk of fire or shock and can damage the components.
Applicable national and local wiring standards and rules must be followed.
l Never connect the I/O module to a power source other than 24VDC. Any
other voltage creates a risk of fire or shock and can damage the hardware.
Do not connect the 24VDC power source to any terminals other than the
24VDC + and – power terminals.
l The shield ground connections of the RS-232 port, LAN port, PoE port, I/O
port and Frame Ground terminal are internally connected. The system
grounding is designed to be at a zero ground potential; this zero ground
potential extends through the cable and to peripheral equipment (e.g. a
vision system, PLC, etc.). To ensure safe operating conditions, it is strongly
recommended that all ground connections are checked to ensure that a
zero ground potential is met.
l The I/O module must be grounded by attaching the I/O module’s Frame
Ground terminal to a frame ground.
l The I/O module is intended for indoor use only.
l Do not install the I/O module where it is directly exposed to environmental
hazards such as excessive heat, dust, moisture, humidity, impact, vibration,
corrosive substances, flammable substances, or static electricity without a
protective enclosure.
