1 Introduction
1.1 Product Overview
The SIOC03 module is an optically isolated converter that converts RS232 to half duplexed
RS485 signals and vice-versa. The converter performs all necessary level shifting required
to interface these two different communication systems.
1.2 Manual Overview
This manual contains specifications, receiving and installation instructions, configuration,
description of operation, and troubleshooting procedures for the SIOC03 Serial Input/Out-
put Converter.
2 Receiving and Installation
2.1 Initial Inspection
The SIOC03 option contains an SIOC03 converter module, two sets of cables for connect-
ing to the EF1, and a 24 VDC power supply. One of the cables is for reflashing the drive's
firmware (marked WF2 Reflash and having an RJ45 connector); the other is for Modbus
communications (marked WF2 Modbus.)
Carefully inspect the SIOC03 for shipping damage or missing components. Report any
shipping damage to your nearest BERGES representative.

3 Connections
3.1 Introduction
This chapter provides information on connecting the required wiring to the SIOC03 convert-
er.
3.2 General Wiring Information
3.2.1 Wiring Practices
Good wiring practice requires separation of low voltage wiring from all power wiring. Power
from inverters and other non-linear loads contain high frequencies that may interfere with
other equipment. Do not run low voltage signal wires in the same conduit or raceway with
power or motor wiring. Observe general RFI suppression measures (refer to the inverter
manuals (electromagnetic compatibility)).
3.2.2 Considerations for Control Wiring
All wiring associated with the SIOC03 converter module is low voltage wiring. Many of the
conductors carry high frequency signals that contain the communication signals. Select this
low voltage wiring as follows:
1. Shielded wire is recommended to prevent electrical noise interference from causing im-
proper operation or nuisance tripping. Connect the shield as recommended by the
equipment manufacturer.
2. Twisted pairs are recommended. The SIO+ and SIO– conductors should be twisted to-
gether. If a twisted pair is used for the power supply connection, the positive voltage and
common conductors should be twisted.
3. Use only VDE, UL or CUL recognized wire.
4. Wire voltage rating must be at least 300 volts.
3.2.3 RS232 Communication Cable
It may be desirable to extend the length of the 9 pin “D” shell connector. To do this requires
a straight through cable assembly (i.e pin 1 connects to pin1; pin 2 to pin 2; etc.). Mouse
extension cables may not perform correctly. To assure reliability, always keep the length of
this connection as short as possible, with an absolute maximum of 25 feet. The cable
should be kept clear of any power signals.
