1-2 Installing Your DeviceNet Adapter Module
Module Installation Compact I/O is suitable for use in an industrial environment when
installed in accordance with these instructions. Specifically, this
equipment is intended for use in clean, dry environments (Pollution
degree 2
1 ) and circuits not exceeding Over Voltage Category II 2 (IEC
60664-1). 3
1. Pollution Degree 2 is an environment where, normally, only non-conductive pollution occurs except that
occasionally a temporary conductivity caused by condensation shall be expected.
2. Over Voltage Category II is the load level section of the electrical distribution system. At this level transient
voltages are controlled and do not exceed the impulse voltage capability of the product’s insulation.
3. Pollution Degree 2 and Over Voltage Category II are International Electrotechnical Commission (IEC)
designations.
Prevent Electrostatic Discharge
Remove Power
System Configuration Refer to Using Banks of I/O on page 3-7 for system configuration
rules.
ATTENTION
!
Electrostatic discharge can damage integrated
circuits or semiconductors if you touch bus
connector pins or the terminal block. Follow these
guidelines when you handle the module:
• Touch a grounded object to discharge static potential.
• Wear an approved wrist-strap grounding device.
• Do not touch the bus connector or connector pins.
• Do not touch circuit components inside the module.
• If available, use a static-safe work station.
• When not in use, keep the module in its static-shield box.
ATTENTION
!
Remove power before removing or inserting this
adapter. When you remove or insert an adapter
with power applied, an electrical arc may occur.
An electrical arc can cause personal injury or
property damage by:
• sending an erroneous signal to your system’s field devices,
causing unintended machine motion
• causing an explosion in a hazardous environment
Electrical arcing causes excessive wear to contacts
on both the module and its mating connector.
Worn contacts may create electrical resistance.
