Ethernet Connection
Connect your Ethernet cable to the Ethernet port on the underside of the
linking device. The factory default for the linking device is Dynamic Host
Configuration Protocol (DHCP) for initial configuration.
H1 Terminal Block
The linking device provides two parallel terminals on each H1 network. Use
one to connect to your fieldbus devices and use the other for short-term
connection of diagnostic devices.
Perform the following steps to connect the H1 cables.
1. Strip about 5…7 mm (0.2…0.28 in.) of the insulation at the ends of
the cable leads.
2. Insert the stripped cable end into the RTB, following the layout on
, and tighten the screw.
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. Be sure that
power is removed or the area is nonhazardous before proceeding
WARNING
When you connect or disconnect the removable terminal block (RTB) with
field-side power applied, 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.
ATTENTION
Be careful when stripping wires. Wire fragments that fall into the linking
device could cause damage.
IMPORTANT
The H1 terminal plugs are keyed so they fit only into the corresponding
socket. Be certain that you are connecting the cables to the correct plugs.
