Installation According To The European Directive Of Electromagnetic Compatibility; Conformal Installation - WEG CFW-11 Serie Guia De Instalacion

Control connection # 4 - Forward/Reverse.
Enabling the Forward/Reverse function.
Parameters to set:
Set DI3 to Forward run: P0265=4
Set DI4 to Reverse run: P0266=5
When the Forward/Reverse function is set, it will be active either in
Local or Remote mode. At the same time, the HMI keys
will remain always inactive (even if P0224=0 or P0227=0).
The direction of rotation is determined by the Forward run and
Reverse run inputs.
Clockwise direction for Forward run and counterclockwise for
Reverse run.
The speed reference can be provided by any source (as in the control
connection # 3).

INSTALLATION ACCORDING TO THE
EUROPEAN DIRECTIVE OF ELECTROMAGNETIC
COMPATIBILITY
The inverters in sizes A to D with FA option (CFW11XXXXXXOFA) and
all the standard inverters in the other sizes have an internal RFI filter
for the reduction of the electromagnetic interference. These inverters,
when properly installed meet the requirements of the electromagnetic
compatibility directive "EMC Directive 2004/108/EC".
ATTENTION!
For using models with internal RFI filters in IT networks
follow the instructions on

Conformal Installation

For the conformal installation use:
1. Inverters on sizes A to D: with internal RFI filters option
CFW11XXXXXXOFA and other standard models.
2. Shielded output cables (motor cables) and connect the shield at
both ends (motor and inverter) with a low impedance connection
for high frequency.
Maximum motor cable length and conduced and radiated emission
levels according to the tables 2
If a lower emission level and/or a longer motor cable were
necessary, then an external RFI filter must be provided at the
inverter input. For more information (RFI filter commercial reference,
motor cable length and emission levels) refer to the
3. Shielded control cables.
4. Inverter solid grounding.
