Introduction

Illustration 1	g03858579

The new CTI enclosure integrates a new 4-pole changeover switch including the electronic controls to meet the standard IEC 60947-6-1.

The CTI enclosure is also available to meet the standard IEC 61439-2.

General Safety Instruction

• This system must always be installed and commissioned by competent and qualified personnel.

• The maintenance operations must be carried out exclusively by authorized and appropriately trained personnel.

• For more information see the Technical Instruction Manual.

Switch Module Interface

(1) ON/OFF LED (2) LED monitor for power positions (3) Cover (4) Manual handle (5) Handle insertion (6) Padlocking mechanism (7) Padlock symbol

The new enclosure design allows direct access to the front panel of the switch module without opening the enclosure for:

• Visualization of the current changeover panel position.

• Functioning mode selection (Cover closed = Automatic / Cover open = Manual).

• Handle for manual operation.

• Handle insertion in manual mode only to guarantee the transfer operation in any situation.

• Padlocking mechanism only in manual mode.

Note: Padlock is not supplied with panel.

Electronic Module Interface

The front panel access of the electronic module includes:

• Sources monitoring by Led: availability

• Sources monitoring by Led: positions I-0-II

• Transfer switches monitoring by Led (Functioning modes, Power supply, Fault)

• Metering (Voltage (V) and Frequency (F) as standard), sequences, timers, and settings display

• Tests operations for "On load " and "Off load"

• Retransfer inhibit (RTI) Led and push button
