ACCESSORIES
DIN Rail Bus Connector Kit
Model XTBUS-KIT Bus Connector Kit for DIN Rail Bus Connection to Power,
compatible with enclosures of Acromag Series XT and uBTA-H product
models.
This kit contains one each of the following terminals
•
DIN Rail Bus Connector 1005-070 for 22.5mm Enclosures.
•
Left Side terminal block, female connector 1005-220.
•
Right Side terminal block, male connector 1005-221.
•
Two End Stops for 35 mm DIN Rails 1027-222 (not shown).
The module is shipped with the first item included in this kit, DIN Rail Bus
Connector 1005-070--this kit offers a spare. Left and right side terminal blocks
that mate directly to the bus connector are also included in this kit. These
terminals are used to optionally (or redundantly) drive power to the carrier
via its DIN rail bus connector. This allows modules to neatly and conveniently
share connections to Power by plugging enclosures together. Two DIN rail
end stops 1027-222, are used to secure the terminal block and module(s) to
the DIN rail for hazardous location installations.
NOTE:
The maximum number of modules that can be plugged-together and
powered from a bus connection will be limited by twice its combined current
draw at a given supply voltage below 3A of maximum allowable current. This
allows you to safely fuse the DIN rail bus power connection with a surge-
tolerant fuse no greater than 2.5A (recommended). Note that current draw is
normally reduced at higher input voltages and current to the unit(s) should
never be allowed to exceed 3A even for bussed powered units. Sustained
current at 3A or above may damage the power circuit, and this could occur
for an over-loaded bus or a sustained over-voltage condition that could drive
an inadvertent short-circuit for a clamped transient voltage suppressor across
the input power terminals of a unit.

mounting
For hazardous location installations (Class I, Division 2 or ATEX / IECEx
Zone 2), you can use two end stops (Acromag 1027‐222) to help secure
modules to 35mm DIN rail (not shown).
