If you have space constraints, you can use the FieldPoint Bus Extender Cable to mount a
FieldPoint bank in two or three rows.
Caution
You should not use more than two FieldPoint Bus Extender Cables per
FieldPoint bank.
Caution
Disconnect power from the network module and terminal bases before
you install the Bus Extender Cable. Do not disconnect a Bus Extender Cable
while the FieldPoint bank is powered on.
Choosing a Configuration
Before you begin installing the Bus Extender Cable, choose a configuration for the
FieldPoint bank. With the Bus Extender Cable, you can mount rows of modules with
terminal blocks together (bottom-to-bottom) or with terminal blocks apart (top-to-top).
Mounting modules with terminal blocks together lets you use one wiring conduit for
two rows of modules and is the recommended method due to cooling considerations.
You should install higher-powered I/O modules on top in this configuration to further help
with cooling. Figure 1 shows configuration examples with two rows. You can use up to
three rows.
