designed for passing on to the operator of the end product. With regard to the specialist
information contained herein, these instructions can serve as a basis for drawing up the
instructions for the end products.
It is essential to note the information contained in these instructions! In doing so, you
can prevent mistakes being made in installing or connecting the system which could result
in…
Ÿinjury and accidents as well as
Ÿdamage to the drive system or the end product.
To supply the voltage, use only a DC power supply!DewertOkin
The DC power supply includes an earth-free electric circuit which is isolated DewertOkin
from the supply voltage via double or reinforced insulation.
DewertOkin accepts no liability for damage caused as a result of …
Ÿnon-observance of these instructions,
Ÿalterations to the product not approved by DewertOkin or
Ÿthe use of spare parts not manufactured or approved by DewertOkin - these may

Caution!
For your own safety!
Shutdown in an emergency is achieved by pulling out the mains plug from the DC
power supply! The mains plug must therefore be accessible at all times when the system
is in operation to ensure it can be quickly pulled out of the wall socket in an emergency.
Avoid subjecting the main's connection lead and connection cables to mechanical loads.
Regular visual checks of the mains connection lead should be carried out at short-term
intervals and in particular each time it has been subjected to a mechanical load.
If the mains connection lead of the DC power supply gets damaged, it must be replaced in
order to prevent hazards. Work to and replacement of the mains connection lead may
only be carried out by specialist personnel holding the qualifications described on
page 3 or by persons who have taken part and successful completed the
corresponding training programmes offered by DewertOkin.
In the Operating Instructions to be drawn up by yourselves, it is essential that you draw the
operator´s attention to the points mentioned here.
3. Getting to Know the System
The CU155 drive control unit is intended for the German market and complies with the Law
applicable in Germany in implementation of relevant EC Directives.
a) Product versions
To operate the drive controls, further components, such as from 1 to 4 slave drives, (5
slave drives optional) handset ... are required.
Reverter-Plug
The optionally available reverter-plug (see page 7) allows flexible adjustment of the motor's
running direction to match the application. The controls and handset can therefore be
standardized.

4. Fitting
Included in the supply package is the drive control unit and depending on the order a DC
power supply, a handset and up one to five slave drives. The components are prewired
and ready to plug in.
a) Installation
The CU155 drive control unit can be screwed to the application at the 4 fixing points using
suitable screws (e.g. M4x50 screws). The surface onto which the controls are mounted
must be level and flat. It is important in the application that no mechanical forces (e.g.
torsional forces etc.) are brought to bear on the drive controls or casing parts. Such forces
can bring about damage (e.g. cracks) to the casing parts.
b) Electrical connection
In the Operating Instructions to be issued by you, point out to the operator that if leads, in
particular the mains connection lead, are driven over they could sustain damage.
Mechanical loads should also be avoided.
When routing the cables make sure that they
Ÿcannot get entangled or trapped,
Ÿare not subjected to mechanical loads (i.e. do not pull, apply pressure or bend),
Ÿcannot get damaged in any other way.
Make sure that the cables, in particular the connection lead of the voltage supply, are
fastened to the application with adequate strain relief and kink protection and that suitable
constructional measures prevent the connection lead from trailing on the floor when the
application is being moved.
First connect the slave drives and controls, as shown (see page 11). Make sure that any
sockets not being used are sealed off with blind plugs, - otherwise the protection category
is not guaranteed. Do not insert the mains plug of the DC power supply until all DewertOkin
the components have been connected to the CU155 control unit. Afterwards fit the plug pull-
out safeguard (see page 7).
Caution!
Only ever connect or disconnect electrical components when they are voltage-free.

d) Fitting the plug pull-out protection
Fit the plug pull-out protection (1) to the drive control unit (2) by allowing it to engage
into the guides (3). Additionally, it can be firmly connected to the drive control system using
suitable screws (4) (ST 2.9 x 6.5; ISO7049).
e) Dismantling
Operate the application to travel to the starting position and disconnect the drive system
from the mains voltage, then the drive control unit from the DewertOkin DC power supply.
Pull-off the (1), take this off first and then the cables from the plug pull-out protection
respective sockets. Loosen the retaining screws - the drive control system can now be
removed from the application.
Caution!
For your own safety!
There is a risk of sustaining injury by getting trapped if the mechanical
connections between the fitting and the drive system are loosened.

c) Fitting the reverter-plug
In order to fit the reverter-plug (5), a fin (6) must be broken off the plug pull-out safeguard
(1) at the relevant socket. This is easy to do by hand. The motor cable plug (7) is then
inserted into the reverter-plug (5) which in turn is inserted into the corresponding socket of
the control system. The plug then sits at the front of the plug pull-out protection (1).
