Before running the tool
Before starting the tool, check that the tool is mounted properly and ensure that the motor drive is
installed properly.
Dimensions specified
in millimeters.
The motor drive PCB comes mounted in a DIN-rail holder that can be attached to a standard 35 x 7.5mm EN50022
DIN-rail, but the motor drive PCB can be removed from this holder and mounted using the mounting holes instead.
If the mounting holes are used, then it is recommended to use 20 mm metal standoffs and 10 mm M3 screws when
mounting the motor drive PCB.
It is recommended to use 10 mm ferrules with plastic sleeve for each wire that is attached to any of the connectors.
The wires can then easily be pushed into the connectors and released with the help of a small flat-head screwdriver
(3.5 mm blade width, 0.6 mm blade thickness).
