3 Installation
3.1 Installation conditions
The permitted ambient temperature (see "Technical Data" Section) must be observed when
installing and operating. The device must be protected against the effects of heat.
3.1.1 Dimensions
Observe the device length of 135 mm (5.31 in) (corresponds to 8TE). More dimensions can be
found in the "Technical Data" Section.
3.1.2 Mounting location
Top-hat rail mounting as per IEC 60715 in the cabinet. The mounting location must be free from
vibrations.
3.1.3 Orientation
No restrictions.
3.2 Installation instructions
First remove the plug-in terminals from the device slots. Now snap the housing onto the top-hat rail
by first hanging the device on the top-hat rail and then pressing it down gently until it engages
(→Fig. 2, items 1 and 2).

3.2.1 Installing extension cards
You can equip the device with various extension cards. A maximum of three slots are available in
the device for this. The slots for the extension cards are marked with B, C and D (→Fig. 3) on the
device.
1. Make sure that the device is not connected to the power supply when installing and removing
an extension card.
2. Remove the blanking cover from the slot (B, C or D) of the basic unit by pressing together the
catches on the bottom of the energy manager (see Fig. 3, item 2), while at the same time
pressing in the catch on the rear of the housing (e.g. with a screwdriver) (see Fig. 3, item 1).
Now you can pull the blanking cover up out of the basic unit.
3. Insert the extension card into the basic unit from above. The extension card is not correctly
installed until the catches on the bottom and rear of the device (see Fig. 3, items 1 and 2) lock
into place. Ensure that the input terminals of the extension card are on top and the connection
terminals are pointing to the front, as with the basic unit.
4. The device automatically recognizes the new extension card once the device has been
correctly wired and has been commissioned (see ’Commissioning’ Section).
!Note!
If you remove an extension card and do not replace it with another card, you must seal the empty
slot with a blanking cover.

Functional description
The remote display is an innovative addition to the powerful RMx621 top-hat rail devices. The user
has the opportunity to optimally install the arithmetic unit to suit the installation and mount the
display and operating unit in a user-friendly way at easily accessible locations. The display can be
connected to both a top-hat rail device without, as well as a top-hat rail device with, an installed
display/operating unit. A 4-pin cable is supplied to connect the remote display with the basic unit;
other components are not necessary.
!Note!
Only one display/operating element can be attached to a top-hat rail device and vice versa (point-

5.2 Local operation
5.2.1 Entering text
There are two ways of entering text in the operating items (see: Setup →Basic setup→Text
input):
a) Standard: individual characters (letters, numbers, etc.) in the text field are defined by scrolling
through the entire row of characters with the up/down cursor until the desired character is
displayed.
b) Palm: a visual key field appears for entering text. The characters on this keyboard are selected
with the cursors. (see "Setup ÆBasic setup")
Using the Palm keyboard
Fig. 15: Example: editing an identifier with the Palm keyboard
1. Using the cursor keys, place the cursor in front of the character before which another character
should be entered. If the entire text should be deleted and rewritten, move the cursor
completely to the right. (see Fig. 15, graphic 1)
2. Press the AB key to enter the editing mode
3. Use the ij/IJ and ½ key to select upper/lower case or numerals. (see Fig. 15, graphic 2)
4. Use the cursors to select the key required and use the tick sign to confirm. If you want to delete
text, select the key in the top right. (see Fig. 15, graphic 2)
5. Edit other characters in this way until the desired text has been entered.
6. Press the Esc key to switch from the editing mode to the display mode and accept changes with
the 'tick' key. (see Fig. 15, graphic 1)
