Installing the Inverter
Authorised electrician
NOTICE
Different manufacturers interpret the standard on which the RS485 protocol is based in different
ways. Note that the wire designations (- and +) for wires A and B can be different depending on the
manufacturer.
NOTICE
Calculating efficiency by measuring the current and voltage values leads to unusable results due to
the tolerances of the measurement devices. The sole purpose of these measured values is to monitor
the basic operation of the system.
Connecting the RS485 bus
Maximum length of the RS485 wiring: 1,200 m under optimal conditions.
Maximum number of connected bus devices: 31 inverters + 1 data monitoring unit.
Use twisted, shielded data lines.
Recommendation (using wire sleeves)
– LI2YCYv (TP) black for laying cable outside and in the ground 2 x 2 x 0.5
– LI2YCY (TP) grey for dry and moist spaces 2 x 2 x 0.5
↻ Drill a hole for the RS485 connection cable into the connection board.
1. Thread the connection cable through the hole.
2. Connect the connection cable to the connection terminals provided (see figure 16 on page 23).
3. Connect the following to all inverters and Kaco-proLOG as follows:
– Wire A (-) with wire A (-) and
– Wire B (+) with wire B (+) (see figure 17 on page 23)
4. Activate the terminating resistor on the terminal unit.
7.4.2 Connecting the remote control line for the power supply company
This connection can be used in the future by your power supply company as an optional remote control line. When
connecting, please observe the polarity (see figure 16 on page 23).
Maximum contact load: 10-24 VDC, 10 mA.
7.4.3 Connecting the S0 output
An S0 pulse output is located on the communication board. Use this output to control accessories such as a large
display, for example. The pulse rate of the output is adjustable.
Connecting the S0 output
↻ Drill a hole for the S0 connection cable into the connection board.
1. Thread the connection cable through the hole.
2. Connect the connection cable to the connection terminals.
7.4.4 Connecting the Ethernet interface
NOTICE
Use a suitable category 5 network cable. The maximum length of a network segment is 100 m.
Ensure that the cable is correctly assigned. The Ethernet connection of the inverter supports autosensing.
You can use both crossed and 1:1 Ethernet connection cables.
