Normally no external current limiting is used. In this case the input can be

switched to +15V.

18z GND 0V reference potential for +5V, +15V, and -15V.

18b -15 V 15V supply for external use. Carrying capacity

-10mA.

18d +15 V -15V supply for external use. Carrying capacity

together with 8z= 10mA.

20z,b,d +UB Plus pole of the d.c. intermediate circuit. Here the plus

pole of a probably existing external d.c. voltage can be

supplied by circumventing the internal rectifier. If an

additional filtering of the intermediate circuit voltage is

necessary, the plus pole of the external electrolyte

capacitor is connected here. An external ballast circuit

can be connected here with the plus pole.

These three contacts have to be connected parallel, as the carrying capacity of

one contact should not exceed 5A for 45°C.

AC1,

Supply inputs of the device. Here all secondary

connections of a transformer are connected. For

protection a fuse has to be built in the supply line.

In no mode of operation and under consideration of all winding tolerances and

line voltage variations, the transformer voltage must never exceed 60VAC (for

60 devices) and 120VAC (for 120V devices)! These three contacts have to be

connected parallel.

26z,b,d Power GND GND of the d.c. intermediate voltage circuit. GND

connection of a probably existing external direct

voltage. The minus pole of the external electrolyte

capacitors has to be connected to 26z,b,d when an

additional filtering of the intermediate circuit voltage is

necessary. An external ballast circuit can be connected

here with your minus pole. The housing of the motor is

to be connected here too.

Power GND is the point, the protective earth terminal has to be connected to.

These three contacts have to be connected parallel.

Output terminals of the power amplifier, to which the

motor will be connected. 32z,b,d to line U, 30z,b,d to

line V and 28z,b,d to line W. Please consider, that

when connecting the motor lines, all three contacts
