About this document 

These operating instructions are part of the product. They must be 
kept in the vicinity of the product at all times. The careful observance 

of these instructions is the precondition for the proper use and the 
correct  operation  of  the  product.  The  operating  instructions 
correspond to the version of the product and the latest state of the 
underlying safety-related standards. 

1.2 

Safety 

These operating instructions contain essential information that must 
be observed during the installation and operation. For this reason, it 
is imperative that these operating instructions are read by both the 

technician as well as the responsible operator before installation and 
commissioning.  Not  only  must  the  general  safety  instructions  be 
observed that are listed under this main item “Safety”, but also the 
specific safety instructions inserted under the following main points 
with hazard symbols.

2.1 

Fields of application, proper use 

This  switchgear  has  been  designed  for  domestic  and  municipal 
sewage, wastewater and rainwater pump stations. 

Please note the following in regard to the controlling of  
pumps operated in an explosive area: The switchgear itself 

must be installed outside of the explosive area. 

The controls are suitable for wastewater submersible motor pumps 
of the type of protection “d” in zone 1 of the mains. The operating 

manuals of the pumps must be observed. 

When  using  external  4  -  20 mA  level  sensors  and  float  switches 
installed in an explosive area, it will be necessary to use components 
with the requisite certifications.  

It  is essential  for  the switching  of  three-phase current motors  that 
both the setting of the electronic motor current monitoring as well 
as for the settings of mechanical motor protection switches that the 
limit values provided below are adhered to. 

2.2 

Personnel qualifications 

Personnel tasked with the installation, commissioning and 

maintenance of the switchgear must hold the requisite 
qualifications. 

2.3 

Safety instructions for the operator 

Observe the existing regulations governing accident prevention, the 
VDE  specifications  and  stipulations  of  the  local  energy  supply 

company.  When  opening  the  device  (removal  of  the  panel  or 
terminal  cover)  or  working  on  the  pumps,  the  control  must  be 
switched off from the power supply through the fuse or a separate 
main switch. 

Due to safety reasons, the unused cable glands must be sealed with 
blanks or blind caps. 

HAZARD due to dangerous voltage 

When working on the open switchgear,  

there is a risk of death from electric shock.

 

For all work on the open 

device  (removal  of  the  cover  or  terminal  cover)  or  work  on  the 

pumps, the control must always be switched off via the backup fuse 
or  a  separate  main  switch  and  secured against  being  switched  on 
again. This work may only be carried out by a qualified electrician. 

2.3.1 

 

Electrical work

 

HAZARD due to dangerous voltage 

There  is  a  risk  of  death  due  to  electric  shock  in  all  work  on  open 
switchgear. During all work on the open device (removal of the panel 

or the terminal cover) or when working on the pumps, the control 
must be switched off from the power supply through the fuse or a 
separate  main  switch  and  secured  against 

reactivation

.

 

To 

disconnect  the  battery,  pull  out  the  red  +  plug  and  isolate  the 

connection with the yellow cap. This work may only be carried out by 
a qualified electrician. 

Beware of moisture! 

The  device  can  be  damaged  by  penetration  of  moisture.  When 
installing,  pay  attention  to  the  permissible  humidity  and  ensure  a 
flood-proof installation.

 

For the connection, refer to chapter 6.0 "Connection". The technical 
information must be observed.

 

2.4 

Dangers of non-compliance with safety 

information  

The  non-compliance  with  the  safety  information  can  lead  to 
endangerment  for  persons  and  product/system.  Non-compliance 
with  the  safety  information  can  lead  to  the  loss  of  all  rights  for 
damage compensation. 

2.5 

Operating instructions 

When  installing,  commissioning  and  maintaining  the  switchgear 
observe the operating instructions. Always observe the limit values 
cited in the manual. 

A fusing on the mains side of max. 3 x 16 A must be 

performed.
