Appendix B
Recommendations for Building
CEĆCompliant Systems
This appendix provides instructions about how to build and install an AutoMax
PC3000 system compliant with the European Union Directives 89/336/EEC,
Electromagnetic Compatibility (EMC), and 73/23/EEC, Low Voltage
requirements.
These instructions are only applicable to the industrial environment as it is
defined in the standards accompanying these Directives.
AutoMax PC3000 Packaged Version (M/N 57C570)
The requirements for an AutoMax PC3000 Packaged Version installation
compliant with the European Union EMC and Low Voltage Directives are:
1. Install the AutoMax PC3000 Packaged Version inside a grounded cabinet.
2. Provide incoming power to the AutoMax PC3000 Packaged Version via a
control transformer. The recommended transformer rating is 0.5 KVA
minimum.
3. Install an EMI/RFI filter between the AutoMax PC3000 Packaged Version and
the control transformer. The Corcom 10VV1 filter (Reliance Electric P/N
612421Ć1) is recommended for both 120 V and 220 V AC. Install the filter as
close to the PC3000 chassis as possible. Connect the filter input to the
control transformer with a shielded cable or twistedĆpair wires of the
appropriate size. If a shielded cable is used, ground the shield at one end.
Connect the filter output to the PC3000 chassis with a shielded cable or
twistedĆpair wires of the appropriate size. Make sure that the wires
connecting the control transformer with the filter input are as far away as
possible from the wires that connect the filter output with the PC3000.
Ground the filter case.
4. Install a surge protection device between the EMI/RFI filter and the control
transformer. The RAVĆ401BWZĆ2A surge protector from Okaya Electric
Industries Co., LTD (Reliance Electric part number 600686Ć44A) is
recommended for a line voltage of 120 V AC. The RAVĆ781BWZĆ2A surge
protector from Okaya Electric Industries Co., LTD (Reliance Electric part
number 600686Ć44B) is recommended for a line voltage of 220 V AC.
If the control transformer secondary is grounded, one surge protector is
required. The surge protector has three wires, labeled terminal 1, ground,
and terminal 2. Connect the surge protector wire labeled 1 or 2 to the filter
input terminal, which is connected to the ungrounded end of the control
transformer secondary. Connect the surge protector's ground wire to the
filter input terminal, which is connected to the ungrounded end of the control
transformer secondary. Make these wires as short as possible. See figure
