Power Supply Voltage - Omron K3FP Series Manual

Mounting
• The K3FP can be mounted on to all 35-mm DIN rail corresponding
to EN 60715. When connecting the K3FP to a DIN rail bus
connector, take particular care with the direction of both the K3FP
and the Power Bridge.
• When connecting to a DIN rail bus connector, mount the DIN rail
bus connector to the DIN rail before connecting the K3FP to the
DIN rail bus connector.
Mounting DIN Rail Bus Connectors
1. Connect the DIN rail bus connectors together.
2. Mount the connectors to the DIN rail.
3. Check the mounting direction.
Mount with the plug on the left side.
Mounting the K3FP
Mount the K3FP with the snap-on
foot at the bottom.
Removing the K3FP
• A DIN rail bus connector supplies the active devices. No DIN rail
bus connector is necessary to operate the K3FP-SN1-1-1 or K3FP-
SN2-1-1 Passive Loop-powered Isolators. It is, however, possible to
snap the passive loop-powered isolators onto a DIN rail bus
connector. An electrically conductive connection is not established
so no existing DIN rail bus connection needs to be disconnected.
• Refer to the Internal Block Diagram for each product for block
diagrams.
• Be sure that the DIN rail is mounted securely with no loose screws.
If the screws are loose, vibration or shock may cause the product or
wiring to become disconnected.

Power Supply Voltage

• Never connect power supply voltage directly to the DIN rail bus
connector.
• Do not draw power from the DIN rail bus connector or from
individual K3FP Units.
• When the total current consumption of the aligned K3FP Units does
not exceed 400 mA, the power can be fed in directly at the
connecting terminal blocks of a K3FP. It is recommended that a
400-mA fuse is connected upstream.
• Be sure power supplies and power lines for control power supply
and inputs have appropriate specifications. Not using power
supplies and power lines with appropriate specifications may result
in malfunction, burning, or electric shock.
