Replacing Modules

General

DANGER
	ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH Disconnect all power from all equipment including connected devices prior to removing any covers or doors, or installing or removing any accessories, hardware, cables, or wires. Place a "Do Not Turn On" or equivalent hazard label on all power switches and lock them in the non-energized position. Wait 15 minutes to allow the residual energy of the DC bus capacitors to discharge. Measure the voltage on the DC bus with a properly rated voltage sensing device and verify that the voltage is less than 42 Vdc. Do not assume that the DC bus is voltage-free when the DC bus LED is off. Block the motor shaft to prevent rotation prior to performing any type of work on the drive system. Do not create a short-circuit across the DC bus terminals or the DC bus capacitors. Replace and secure all covers, accessories, hardware, cables, and wires and confirm that a proper ground connection exists before applying power to the unit. Use only the specified voltage when operating this equipment and any associated products. Failure to follow these instructions will result in death or serious injury.

DANGER

ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH

Disconnect all power from all equipment including connected devices prior to removing any covers or doors, or installing or removing any accessories, hardware, cables, or wires.
Place a "Do Not Turn On" or equivalent hazard label on all power switches and lock them in the non-energized position.
Wait 15 minutes to allow the residual energy of the DC bus capacitors to discharge.
Measure the voltage on the DC bus with a properly rated voltage sensing device and verify that the voltage is less than 42 Vdc.
Do not assume that the DC bus is voltage-free when the DC bus LED is off.
Block the motor shaft to prevent rotation prior to performing any type of work on the drive system.
Do not create a short-circuit across the DC bus terminals or the DC bus capacitors.
Replace and secure all covers, accessories, hardware, cables, and wires and confirm that a proper ground connection exists before applying power to the unit.
Use only the specified voltage when operating this equipment and any associated products.

Failure to follow these instructions will result in death or serious injury.

Unsuitable parameter values or unsuitable data may trigger unintended movements, trigger signals, damage parts and disable monitoring functions. Some parameter values or data do not become active until after a restart.

WARNING
	UNINTENDED EQUIPMENT OPERATION Only start the system if there are no persons or obstructions in the zone of operation. Do not operate the drive system with undetermined parameter values or data. Never modify a parameter value unless you fully understand the parameter and all effects of the modification. Restart the drive and verify the saved operational data and/or parameter values after modifications. Carefully run tests for all operating states and potential error situations when commissioning, upgrading or otherwise modifying the operation of the drive. Verify the functions after replacing the product and also after making modifications to the parameter values and/or other operational data. Failure to follow these instructions can result in death, serious injury, or equipment damage.

WARNING

UNINTENDED EQUIPMENT OPERATION

Only start the system if there are no persons or obstructions in the zone of operation.
Do not operate the drive system with undetermined parameter values or data.
Never modify a parameter value unless you fully understand the parameter and all effects of the modification.
Restart the drive and verify the saved operational data and/or parameter values after modifications.
Carefully run tests for all operating states and potential error situations when commissioning, upgrading or otherwise modifying the operation of the drive.
Verify the functions after replacing the product and also after making modifications to the parameter values and/or other operational data.

Failure to follow these instructions can result in death, serious injury, or equipment damage.

Electrostatic discharge (ESD) may permanently damage the module either immediately or over time.

NOTICE
	EQUIPMENT DAMAGE DUE TO ESD Use suitable ESD measures (for example, ESD gloves) when handling the module. Do not touch internal components. Failure to follow these instructions can result in equipment damage.

Removing the Safety Module eSM

Procedure for removing the safety module eSM:

Save the parameters of the safety module eSM (refer to Menu Item "Duplicate").
Duplicate the drive device settings, refer to the user guide of the drive (Related Documents).
Disconnect all power.
Wait 15 minutes to allow the residual energy of the DC bus capacitors to discharge.
Remove the safety module eSM according to the instructions in the user guide of the drive (Related Documents).
The drive detects an error (restore factory settings) after the module is removed, refer to the user guide of the drive (Related Documents).

Installing a New Safety Module eSM

Procedure for installing the safety module eSM:

Disconnect all power.
Wait 15 minutes to allow the residual energy of the DC bus capacitors to discharge.
Install the safety module eSM as described in Installation.
Commission the safety module eSM as described in Commissioning. If you have stored an eSM parameter set, you can duplicate it, see Menu Item "Duplicate".

NOTE: If a safety module eSM is removed from one drive and installed in another drive, the eSM parameters are reset to their factory settings.
