SYSTEM DRIVES

 PCS6000

3.1. Overview

 The following tables indicate all converter service tools required for service work on the 

PCS6000 with their ABB order number (SAP number). 

Product safety labels

 Product safety labels on the equipment alert you to the hazards that can occur when you 

work on or operate the equipment.– Always follow the instructions on the labels to avoid the hazard– Keep the labels in a perfectly legible condition

 For the location of the labels, see the label placement document for the drive

 2.3. Electrical safety

 The following electrical safety instructions are based on EN 50110.

 2.3.1. General safety instructions

 1) Minimize hazards.

 2) Before energizing the drive:

 • Remove all foreign objects are from the drive

 • Fasten all internal and external covers securely

 • Close, lock, and/or bolt all doors

 • Move the release dial of the door safety switches into the locked position

 3) Before working on the drive:

 • Turn off, lock out, and tag out the main and auxiliary power supplies to the drive 

• De-energize the drive

 • Ensure that the safety ground connections are in place

 • Ensure that the appropriate personal protective equipment (PPE) is available and 

used when required

 • Inform the involved personnel about the potential safety hazards

 • Wear hearing protection when a drive is running.

 4) Before working simultaneously on the drive and on other drive system equipment:

 • Observe the relevant safety codes and standards

 • Turn off all energy sources for the equipment

 • Ensure that all lockout and tagout devices are in place

 • Install barriers around and use appropriate covers on the equipment that is still 

energized

 • Inform the involved personnel about the potential safety hazards

 5) In case of fire in the drive room:

 • Observe the established rules and regulations for fire safety

 • Only allow firefighters with the appropriate PPE to enter the drive room

 2.3.2. The 7 steps that save lives

 ABB’s 7 steps that save lives concept is a series of actions that must take place prior to 

commencing work on or near electrical installations.

 1) Prepare for the work: do an on-site risk assessment or job hazard analysis that 

considers the limits of approach for shock and arc-flash.

 • Be in possession of a clear work order to execute the work.

 • When required, the access or work permit is to be obtained by a person who is 

authorized for the specific electrical system.

 • Engage the person responsible for electrical equipment or system to review single

line diagrams, schematics, switching plans, etc.

 • Ensure the competence of workers.

 • Check for proper tools for the job.

 • Determine and select the proper arc-rated Personal Protective Equipment (PPE).

 • Decide of the appropriate work methods and initiate the Permit To Work (PTW) 

process.

 2) Clearly identify the work location and equipment.

 • Use your senses (sight, hearing and smell) to identify problem areas.

 • Define the work area via barriers and barricading and label equipment.

 • Avoid distractions such as talking or texting on the phone.

 3) Disconnect all sources of supply and secure against reconnection by applying 

Lockout/Tagout.

 • If ABB is responsible for switching and it cannot be done remotely, then the person 

performing the switching must be properly trained and wearing the proper PPE 

identified in step 1.

 • The Person in Charge of Work (PICW) must ensure that switching is performed in the 

proper manner by witnessing it from a safe distance if present on site or by engaging 

the person responsible for switching to identify all isolation points.

 • Apply Lockout/Tagout (LOTO) to the energy isolation device and if multiple energy 

isolation devices are involved, then Group LOTO must be implemented with the PICW 

serving as the Group LOTO Leader.

 4) Verify the absence of operating voltage: always test before you touch!

 Only use properly rated and inspected voltage detection devices and wear proper PPE 

identified in step 1:

 • Test voltage detection device

 • Test for voltage

 • Test voltage detection device

 It is highly important that the voltage detection device is tested on a known voltage 

source such as a Proving Unit or by performing an internal self-test, according to the 

manufacturer’s instructions, before and after testing for the absence of operating 

voltage
