Perform the minimum system connection. Please refer to section 6.1 for minimum
connection requirements. Observe the rules and warnings below carefully:
DANGER!
Hazard of electrical shock! Circuit potentials are up to 480 VAC
above earth ground. Avoid direct contact with the printed circuit board
or with circuit elements to prevent the risk of serious injury or fatality.
Disconnect incoming power and wait 60 seconds before servicing drive.
Capacitors retain charge after power is removed.
STOP!
• The PositionServo 940 must be mounted vertically for safe
operation and enough cooling air circulation.
• Printed circuit board components are sensitive to electrostatic
fields. Avoid contact with the printed circuit board directly. Hold the
PositionServo 940 by it’s case only.
• Protect the drive from dirt, filings, airborne particles, moisture,
and accidental contact. Provide sufficient room for access to the
terminal block.
• Mount the drive away from any and all heat sources. Operate
within the specified ambient operating temperature range.
Additional cooling with an external fan may be recommended in
certain applications.
• Avoid excessive vibration to prevent intermittent connections
• DO NOT connect incoming (mains) power to the output motor
terminals (U, V, W)! Severe damage to the drive will result.
• Do not disconnect any of the motor leads from the PositionServo
940 drive unless (mains) power is removed. Opening any one
motor lead may cause failure.
• Control Terminals provide basic isolation (insulation per EN61800-
5-1). Protection against contact can only be ensured by additional
measures, e.g., supplemental insulation.
WARNING!
For compliance with EN61800-5-1, the following warning applies.
This product can cause a d.c. current in the protective earthing
conductor. Where a residual current-operated protective (RCD) or
monitoring (RCM) device is used for protection in case of direct or
indirect contact, only an RCD or RCM of Type B is allowed on the
supply side of this product.
