1.3.10
Earthing!
It is vital that you ensure that the drive is safely earthed to the PE (protective earth) busbar in the
switch cabinet. Risk of electric shock. Without low-resistance earthing no personal protection can
be guaranteed.
1.4
Leakage Current!
Since the leakage current to PE is more than 3.5 mA, in compliance with IEC61800-5-1 the PE
connection must either be doubled or a connecting cable with a cross-section >10 mm² must be
used. Deviating measures according to regional standards might be possible.
1.4.1
High Voltages!
The equipment produces high electric voltages up to 900 V. Risk of electric shock. Do not open or
touch the equipment during operation. Keep all covers and cabinet doors closed. During operation,
drives may have uncovered live sections, according to their level of enclosure protection.
Lethal danger exists at live parts of the device. Built-in protection measures such as insulation or
shielding may not be removed. Work on the electrical installation may only be performed by
trained and qualified personnel, in compliance with the regulations for safety at work, and only with
switched off mains supply, and secured against restart.
Never undo any electrical connections to the drive while it is live. There is a danger of electrical
arcing with damage to contacts and personal injury. Wait at least 7 minutes after disconnecting the
drive from the main supply power before touching potentially live sections of the equipment (such
as contacts) or removing any connections.
Always measure the voltage in the DC bus link and wait until the voltage is below 50 V before
handling components.
1.4.2
Functional Safety!
The STO safety implementation on the PSD is qualified. The assessment of the safety functions
according to EN13849 or EN 62061 must finally be done by the user.
1.4.2.1
Reinforced Insulation
Thermal sensors, motor holding brakes and feedback systems built into the connected motor must
have reinforced insulation (according to IEC61800-5-1) against system components with power
voltage, according to the required application test voltage. All Emerson components meet these
requirements.
1.4.2.2
Never modify the drive!
It is not allowed to modify the drive hardware without permission by the manufacturer. Opening
the housing causes loss of warranty.
1.4.3
Use as Directed
The PACMotion Servo Drives (PSD) are exclusively intended for driving suitable synchronous
servomotors with closed-loop control of torque, speed, and/or position.
PSDs are components that are built into electrical plants or machines and can only be operated as
integral components of these plants or machines. The manufacturer of the machine used with a
drive must generate a risk assessment for the machine. When the drives are built into machines or
plant, the drive must not be used until it has been established that the machine or plant fulfills the
requirements of the regional directives.
