Hazards
DANGER! - Ignoring the following may result in injury
1. This equipment can endanger life by exposure to
rotating machinery and high voltages.
2. The equipment must be permanently earthed due to
the high earth leakage current, and the drive motor
must be connected to an appropriate safety earth.
3. Ensure all incoming supplies are isolated before
working on the equipment. Be aware that there may
be more than one supply connection to the drive.
4. There may still be dangerous voltages present at
power terminals (motor output, supply input phases,
DC bus and the brake, where fitted) when the motor
is at standstill or is stopped.
5. For measurements use only a meter to IEC 61010 (CAT
III or higher). Always begin using the highest range.
CAT I and CAT II meters must not be used on this
product.
6. Allow at least 10 minutes for the stack controllers
capacitors to discharge to safe voltage levels (<50V).
Use the specified meter capable of measuring up to
1000V dc & ac rms to confirm that less than 50V is
present between all power terminals and between power
terminals and earth.
7. Unless otherwise stated, this product must NOT be
dismantled. In the event of a fault the drive must be
returned. Refer to "Routine Maintenance and Repair".
WARNING! - Ignoring the following may result in injury or damage to equipment
SAFETY
Where there is conflict between EMC and Safety requirements, personnel safety shall always take precedence.
• Never perform high voltage resistance checks on the
wiring without first disconnecting the drive from the
circuit being tested.
• Whilst ensuring ventilation is sufficient, provide
guarding and /or additional safety systems to prevent
injury or damage to equipment.
• When replacing a drive in an application and before
returning to use, it is essential that all user defined
parameters for the product’s operation are correctly
installed.
• All control and signal terminals are SELV, i.e. protected
by double insulation. Ensure all external wiring is rated
for the highest system voltage.
• Thermal sensors contained within the motor must have at
least basic insulation.
• All exposed metalwork in the Drive is protected by basic
insulation and bonded to a safety earth.
• RCDs are not recommended for use with this product
but, where their use is mandatory, only Type B RCDs
should be used.
CAUTION!
APPLICATION RISK
• The specifications, processes and circuitry described herein are for guidance only and may need to be adapted to the
user’s specific application. We can not guarantee the suitability of the equipment described in this Manual for
individual applications.
RISK ASSESSMENT
Under fault conditions, power loss or unintended operating conditions, the stack controller may not operate as intended.
In particular:
• Stored energy might not discharge to safe
levels as quickly as suggested, and can still be present
even though the drive appears to be switched off
• The motor's direction of rotation might not be controlled
• The motor speed might not be controlled
•
The motor might be energised
The stack controller is a component within a drive or drive system that may influence its operation or effects under a fault
condition. Consideration must be given to:
• Stored energy • Supply disconnects • Sequencing logic • Unintended operation
