2.1.3 SK …-3H – Handheld Version
2.1.3.1 SimpleBox SK CSX-3H – Handheld Version
The SK CSX-3H SimpleBox is a compact control device for
direct connection to the frequency inverter via the RJ12
diagnostic socket. A normal RJ12 -patch cable ("Modular
cable RJ12 (6/6) - RJ12 (6/6), 1:1 assignment") with a
length of up to 3m can be used for connection.
If the SimpleBox is supplied from a power source with a
higher voltage (e.g. 24V
DC
from SK 200E), the cable can be
considerably longer.
2.1.3.2 ParameterBox SK PAR-3H – Handheld Version
The SK PAR-3H ParameterBox is a compact control device
for direct connection to the frequency inverter via the RJ12
diagnostic socket. A normal RJ12 -patch cable ("Modular
cable RJ12 (6/6) - RJ12 (6/6), 1:1 assignment") with a
length of up to 3m can be used for connection.
If the ParameterBox is supplied from a power source with a
higher voltage (e.g. 24V
DC
from SK 200E), the cable can be
considerably longer.
A normal USB device connection cable (USB2.0 connection
cable, Series A plug to Series B plug) is required to connect
a PC or laptop.
WARNING
The SK PAR-3H ParameterBox must never be connected simultaneously to the frequency
inverter and the PC, as otherwise this may cause damage, especially to the PC.
2.1.3.3 Electrical Connection
The parameter boxes SK CSX-3H and SK PAR-3H are only
connected to a frequency inverter via the RJ12 socket. This
connection also provides the power supply to the box.
A termination resistor (220Ω) for the RS485 bus system is
integrated into the module. Therefore the ParameterBox
should only be connected as the first or last participant.
Connection of the SK PAR-3H ParameterBox to a PC is
made via the USB interface integrated into the box. This
connection also provides the power supply to the box.
The necessary driver software for the USB interface on the
PC is supplied with the enclosed CD "EPD", but is also
available free of charge on our Internet page
(www.nord.com
).
