LTMTCUF Control Operator Unit Mounting - TeSys Tera Motor Management System

Inserting the Local Control Interface Label

The local control interface is the part of the LTMTCUF control operator unit that contains the five control keys and four LEDs. To identify these different elements, you can choose:

One of the pre-defined labels
The blank label that you can customize with a pen

The diagram below shows an example of a pre-defined label:

NOTE: Pre-defined labels and a blank label are delivered with the LTMTCUF control operator unit. The label must be chosen according to the LTMTCUF control operator unit operating mode. The control keys label on the local control interface must be appropriate to the functions of the LTMTCUF control operator unit operating mode.

Inserting Labels

To insert a local control interface label:

Slide the tip of the label into the slit on the side of the LTMTCUF control operator unit.

NOTE: Be careful to use the right slit as shown in the zoom view below.
Slide the rest of the label into position in the LTMTCUF control operator unit, making sure that the identifiers on the label are correctly aligned with the interface elements.
Insert the label tab into the tab loop.
Push the tab into place so it lies flat against the loop.

Panel Setup

To setup the panel, follow the steps below:

Check that the panel surface is flat, in good condition, and has no jagged edges. Metal reinforcing strips can be attached to the inside of the panel, near the panel opening, to increase the panels rigidity.
The thickness of the panel should be from:
- 3.5 to 6 mm (0.1 to 0.2 in.) with additional washer.
- 0.8 to 3.5 mm (0.03 to 0.1 in.) without additional washer.
Be sure that the ambient operation temperature and the ambient humidity are within their designated ranges. When installing the LTMTCUF control operator unit in an enclosure, the ambient operation temperature is the enclosures internal temperature.
Be sure that heat from surrounding equipment does not cause the LTMTCUF control operator unit to exceed its standard operating temperature. For more information, refer to the Environmental Characteristics section in the TeSys Tera Motor Management System LTMTCUF Control Operator Unit User Guide – DOCA0233EN.

Operating Position

When installing the LTMTCUF control operator unit in a slanted panel, the panel face should not incline more than 30°.

NOTE: When installing the LTMTCUF control operator unit in a slanted panel, and the panel face inclines more than 30° C (86° F), the ambient temperature must not exceed 40 °C (104 °F).

Flush Mounting Procedure Inside Panel Cutout

The flush mounting procedure is as follows:

Insert the LTMTCUF control operator unit into the panel cut.
Position the metallic washer to the unit only if the panel thickness is more than 3.5 mm (0.14 in.).

NOTE: A metallic washer is not required if the panel thickness is less than 3.5 mm (0.14 in.).
Position the clamp to the unit.
Insert the locking nut and tighten it to a torque of 1 N•m (9 lb-in).
