Control card, 24 V DC output:
Terminal number
12, 13
Output voltage
24 V +1, -3 V
Max. load
200 mA
The 24 V DC supply is galvanically isolated from the supply voltage (PELV), but has the same
potential as the analog and digital inputs and outputs.
Control card, 10 V DC output:
Terminal number
50
Output voltage
10.5 V ±0.5 V
Max. load
15 mA
The 10 V DC supply is galvanically isolated from the supply voltage (PELV) and other high-voltage
terminals.
Control card, RS-485 serial communication:
Terminal number
68 (P,TX+, RX+), 69 (N,TX-, RX-)
Terminal number 61
Common for terminals 68 and 69
The RS-485 serial communication circuit is functionally separated from other central circuits and
galvanically isolated from the supply voltage (PELV).
Control card, USB serial communication:
USB standard
1.1 (Full speed)
USB plug
USB type B “device” plug
Connection to PC is carried out via a standard host/device USB cable.
The USB connection is galvanically isolated from the supply voltage (PELV) and other high-volt-
age terminals.
The USB ground connection is not galvanically isolated from protection ground. Use only an
isolated laptop as PC connection to the USB connector on the adjustable frequency drive.
