3.4 Fitting the IOP and the blanking plate

3.4 Fitting the IOP and the blanking plate
Overview
The Inverter has been designed to allow an Intelligent Operator Panel to be fitted to the front
of the inverter.
If an IOP is not to be fitted to the Inverter, then the supplied blanking plate must be fitted to
maintain the IP55/UL Type 12 rating.
The fitting of the IOP or blanking plate uses the same technique. To fit the IOP or blanking
plate to the Inverter the following procedure should be performed:
1. Fit the bottom-edge of the IOP or blanking plate into the panel recess on the front of the
Inverter (see diagram below).
2. Push the IOP or blanking plate forward, towards the Inverter until it clicks into place (see
diagram below).
Removal
To remove the IOP or blanking plate from the Inverter the following procedure should be
performed.
1. Insert a small-bladed screwdriver into the cover recess to push down the IOP/Blanking
Plate release mechanism (see figure below).
2. Pull the IOP/Blanking Plate forward, away from the housing.
3. The IOP/Blanking Plate can now be lifted from the bottom recess of the casing.
Removal of IOP from the Inverter
The IOP has no internal, independent power supply; should the IOP be removed from
the Inverter then all data store within the IOP's memory will be lost.
If the IOP is removed from the Inverter during a process, such as, commissioning or
parameter upload or download; that process will be interrupted and the Inverter will be in
an unknown state and could result in an unstable system. Ensure that all processes
(regarding the IOP) are completed before removing the IOP from the Inverter.
