Power Supply Connection
The power supply is connected to the ZPA motor control module via a black AS-Interface flat
cable. The permissible supply voltage is 18 V ... 30 V.
The electric connection between the ZPA motor control module and flat cables is established
via two metal pins using piercing technology. The flat cable is routed through a hinged cable
guide. When closed, the cable guide is locked using a locking bracket and can be opened
again without the need for tools.
The profiled flat cable has a narrow upper side (with a visibly offset profile edge) and a wide
under side (profile edge not visible). The cable guide allows the flat cable to be inserted on
both sides, for flexible connection of flat cables already laid in cable ducts. However, you must
make sure that the profile edge always points to the motor control module. Mechanical reverse
polarity protection prevents complete closure of the cable guide if the flat cable is inserted
incorrectly.
Connecting Flat Cables on the Narrow Side
The profile edge is visible from above.
1. Open the cable guide. To do this, push the locking bracket (1) slightly to one side.
2. Insert the black flat cable with the profile edge (2) to the ZPA motor control module into the
upper duct (see module tag "PWR").
3. Make sure that the profile edge of the flat cable is under the respective reverse polarity
protection (3).
4. Close the cable guide. It must engage securely in the locking bracket (1).
The metal pins contact the cores of the flat cable.
Caution!
If a flat cable is inserted incorrectly, the ZPA motor control module will not work.
If the flat cable is inserted in the cable guide in the wrong direction, the voltage is inverted. The
ZPA motor control module will not work. However, internal electrical reverse polarity protection
protects it against breakage.
