read and the safety instructions have been observed.
1.1 Designated use
The Pump Manager is used to control pumps. The input values and calculated values can be stored
in the device and evaluated at a later time either at the device or by means of an external system.
There are various ways of establishing the connection to this external system: RS232/485,
connection via Ethernet, OPC, M-Bus or Mod-Bus.
• The device is seen as accessory equipment and may not be installed in hazardous areas.
• The manufacturer does not accept liability for damage caused by improper or non-designated use.
The device may not be converted or modified in any way.
• The device is designed for use in industrial environments and may only be operated in an installed
state.
1.2 Installation, commissioning and operation
This device has been safely built with state-of-the-art technology and meets the applicable

improperly or other than intended. Installation, wiring, commissioning and maintenance of the
device must only be carried out by trained technical personnel. Technical personnel must have read
and understood these Operating Instructions and must adhere to them. The information in the
electrical wiring diagrams (see Section 4 ’Wiring’) must be observed closely.
1.3 Operational safety
Technical improvement
The manufacturer reserves the right to adapt technical details to the most up-to-date technical
developments without any special announcement. Contact your local sales center for information

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.

!Note!
The inputs in the same slot are not galvanically isolated. There is a separation voltage of 500 V
between the inputs and outputs mentioned above in different slots. Terminals of the same name are
jumpered internally (terminals 11 and 81).
4.2 Connecting the measuring unit
"Caution!
Do not install or wire the device when it is connected to the power supply. Not conforming with
this can lead to the destruction of electronic components.
4.2.1 Power supply connection
"Caution!
• Before wiring the device, ensure that the supply voltage corresponds to the specification on the
nameplate.
• For the 90 to 250 V AC version (power supply connection), a switch marked as a separator, as
well as an overvoltage organ (rated current = 10 A), must be fitted in the supply line near the
device (easy to reach).
