ACU User Interface (UI)


ACU UI Package Content

- ACU UI Module.

- Stickers with numbers 1, 2.



ACU UI Installation

ACU UI can be used in most environments, including residential, commercial and light-industrial environments. 


Do not install ACU UI inside a metal cabinet, because it would block radio signals to and from the built-in antenna.


ACU UI shall be mounted on a flat wall. For mouning on a rounded surface use ACU pedestal mount (PM). The mounting height shall

be chosen so that a standing person, as well as a wheelchair user, is comfortable reaching the keypad and reading from the



Use four screws (not included) to fasten the ACU UI to the wall. Distance between mounting screws, WxH: 55x232 mm.


Apply the included number stickers to the products controlled by ACU.


ACU Contactor Module (CM)


ACU CM Package Content

- ACU Contactor Module.

- Cat 5E cable, 0.9 m.

- Ferrite snap-on core.

- Stickers with numbers 3-5.


ACU CM Installation

ACU CM shall be installed into an outdoor power post. Do not use ACU CM in residential environments.


ACU CM is mounted on a standard 35 mm DIN rail. There are two compression springs pressing the CM against the DIN rail. In order

to install the CM, put the bottom part onto the DIN rail first, then push the CM up and fit the top part onto the DIN rail.


It is also possible to mount CM to a wall using two cheese-headed 3.5 mm screws placed 54 mm apart on a horisontal line.


Install the included ferrite snap-on core onto the Cat 5E cable. The ferrite shall be placed inside the ACU UI module housing

and the cable shall be fastened with a cable tie near the ferrite. 


Apply the included number stickers 1-4 to the power post outlets. The outlet numbers must match screw terminal numbering at the CM module

Outlet 1 : L12 and N12

Outlet 2 : L22 and N22

Outlet 3 : L32 and N32

Outlet 4 : L42 and N42

When installation and connection is finished, apply power. ACU shall boot into delivery mode.

Follow instructions on the screen and press buttons to test activation of the connected equipment

from the ACU.


Then send the ACU serial number with the connection chart number to GoMarina for final

configuration.  Leave the ACU powered on.
