MOUNTING

Firmly pull DIN Rail Release Tab
to unlatch unit from rail.

Where applicable, rotate Locking
Wheel to unlock Bus Coupler

r

For system assembly, rst attach a bus coupler by
snapping onto 35mm DIN rail and securing into posi­tion using the DIN rail locking wheel (where applicable)
located on the left side of the coupler. To add a bus
terminal, insert unit onto right side of bus coupler using
the tongue and groove at the top and bottom of the
unit, pressing gently until it snaps onto the DIN rail.
A proper connection cannot be made by sliding the
units together on the DIN rail. When correctly installed,

no signicant gap can be seen between the attached

units. Bus connection is made through the six slide
contacts located on the upper right side of the units.
Add up to 64 bus terminals per bus coupler, including a
bus end terminal.

Insert unit using tongue and groove
molded guide and press gently until
it becomes firmly seated on DIN rail.

Where applicable, rotate Locking
Wheel to lock Bus Coupler

Align tab with
molded guide

ra.

REMOVAL

A locking mechanism prevents individual units from
being pulled off. For bus terminal removal, pull the

orange DIN rail release tab rmly to unlatch the unit

from the rail. If attached to other terminal units, slide
unit forward until released. For bus couplers with
locking wheels, release the DIN rail locking wheel, then

pull rmly on DIN rail release tab.

WIRING CONNECTION

Wire connection is made through a spring clamp style
terminal. This terminal is designed for a single-conductor

solid or stranded wire. Wire connection is made by rmly

pushing the screwdriver into the screwdriver slot, inserting
the wire into the wire slot and removing the screwdriver,
locking the wire into position.

HOT SWAP NOT PERMITTED

Always remove power from the system before inserting or
removing bus terminals or couplers as failure to do so could
cause malfunction or damage to the terminals, couplers or
other connected devices.
