Control card, +10 V DC output
Terminal number 50
Output voltage 10.5 V ±0.5 V
Maximum load 15 mA
The 10 V DC supply is galvanically isolated from the supply voltage (PELV) and other high-voltage terminals.
Control card, RS485 serial communication
Terminal number 68 (P,TX+, RX+), 69 (N,TX-, RX-)
Terminal number 61 Common for terminals 68 and 69
The RS485 serial communication circuit is galvanically isolated from the supply voltage (PELV).
Control card, USB serial communication
USB standard 1.1 (full speed)
USB plug USB type B 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-voltage terminals.
The USB ground connection is not galvanically isolated from protective earth. Use only an isolated laptop as PC connection to
the USB connector on the frequency converter.
