Preventing Electrostatic Discharge
ATTENTION
This product is grounded through the DIN rail to chassis ground. Use zinc
plated yellow-chromate steel DIN rail to assure proper grounding. The use of
other DIN rail materials (for example, aluminum and plastic) that can corrode,
oxidize, or are poor conductors, can result in improper or intermittent
grounding. Secure DIN rail to mounting surface approximately every 200 mm
(7.8 in.) and use end anchors appropriately.
ATTENTION
This equipment is sensitive to electrostatic discharge, which can cause
internal damage and affect normal operation. Follow these guidelines when
you handle this equipment:
•
Touch a grounded object to discharge potential static.
•
Wear an approved grounding wriststrap.
•
Do not touch connectors or pins on component boards.
•
Do not touch circuit components inside the equipment.
•
Use a static-safe workstation, if available.
•
Store the equipment in appropriate static-safe packaging when not in
use.
ATTENTION
To reduce susceptibility to noise, power analog modules and digital modules
from separate power supplies.
ATTENTION
Do not exceed a length of 3 m (9.8 ft) for DC power cabling.
ATTENTION
To comply with the CE Low Voltage Directive (LVD), all connected I/O must be
powered from a source compliant with the following:
Safety Extra Low Voltage (SELV) or Protected Extra Low Voltage (PELV).
