4 POINT I/O 24V DC Expansion Power Supply
WARNING: When you insert or remove the module while backplane power
is on, an electrical arc can occur. This could cause an explosion in hazardous
location installations. Be sure that power is removed or the area is
nonhazardous before proceeding. Repeated electrical arcing causes
excessive wear to contacts on both the module and its mating connector.
Worn contacts may create electrical resistance that can affect module
operation.
WARNING: If you connect or disconnect the communication cable with
power applied to this module or any device on the network, an electrical arc
can occur. This could cause an explosion in hazardous location installations.
ATTENTION: To comply with the CE Low Voltage Directive (LVD), field power
and 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).
ATTENTION: If this equipment is used in a manner not specified by the
manufacturer, the protection provided by the equipment may be impaired.
ATTENTION: To comply with UL restrictions, field power and all connected
devices must be powered from a single source compliant with the following:
Class 2.
ATTENTION: POINT I/O 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, 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.
