M-Max Series Adjustable Frequency Drive
Safety
Warning!
Dangerous Electrical Voltage!

Before Commencing the Installation

Disconnect the power supply of the device
●
Ensure that devices cannot be accidentally restarted
●
Verify isolation from the supply
●
Earth and short circuit the device
●
Cover or enclose any adjacent live components
●
Follow the engineering instructions (IL04020001E) for the
●
device concerned
Only suitably qualified personnel in accordance with
●
EN 50110-1/-2 (VDE 0105 Part 100) may work on this
device/system
Before installation and before touching the device ensure
●
that you are free of electrostatic charge
The functional earth (FE, PES) must be connected to the
●
protective earth (PE) or the potential equalization. The
system installer is responsible for implementing this
connection
Connecting cables and signal lines should be installed so
●
that inductive or capacitive interference does not impair
the automation functions
Install automation devices and related operating elements
●
in such a way that they are well protected against
unintentional operation
Suitable safety hardware and software measures should
●
be implemented for the I/O interface so that an open
circuit on the signal side does not result in undefined
states in the automation devices
Ensure a reliable electrical isolation of the extra-low
●
voltage of the 24V supply. Only use power supply units
complying with IEC 60364-4-41 (VDE 0100 Part 410) or
HD384.4.41 S2
Deviations of the input voltage from the rated value must
●
not exceed the tolerance limits given in the specifications,
otherwise this may cause malfunction and dangerous
operation
Emergency stop devices complying with IEC/EN 60204-1
●
must be effective in all operating modes of the automation
devices. Unlatching the emergency-stop devices must not
cause a restart
Devices that are designed for mounting in housings or
●
control cabinets must only be operated and controlled
after they have been installed and with the housing closed.
Desktop or portable units must only be operated and
controlled in enclosed housings

Measures should be taken to ensure the proper restart of
●
programs interrupted after a voltage dip or failure. This
should not cause dangerous operating states even for a
short time. If necessary, emergency-stop devices should
be implemented
Wherever faults in the automation system may cause
●
injury or material damage, external measures must be
implemented to ensure a safe operating state in the event
of a fault or malfunction (for example, by means of
separate limit switches, mechanical interlocks, and so on)
Depending on their degree of protection, adjustable
●
frequency drives may contain live bright metal parts,
moving or rotating components, or hot surfaces during and
immediately after operation
Removal of the required covers, improper installation, or
●
incorrect operation of motor or adjustable frequency drive
may cause the failure of the device and may lead to
serious injury or damage
The applicable national accident prevention and safety
●
regulations apply to all work carried out on live adjustable
frequency drives
The electrical installation must be carried out in
●
accordance with the relevant regulations (for example,
with regard to cable cross sections, fuses, PE)
Transport, installation, commissioning, and maintenance
●
work must be carried out only by qualified personnel
(IEC 60364, HD 384 and national occupational safety
regulations)
Installations containing adjustable frequency drives must
●
be provided with additional monitoring and protective
devices in accordance with the applicable safety
regulations. Modifications to the adjustable frequency
drives using the operating software are permitted
All covers and doors must be kept closed during operation
●
To reduce hazards for people or equipment, the user must
●
include in the machine design measures that restrict the
consequences of a malfunction or failure of the drive
(increased motor speed or sudden standstill of motor).
These measures include:
Other independent devices for monitoring safety-related
●
variables (speed, travel, end positions, and so on)
Electrical or non-electrical system-wide measures
●
(electrical or mechanical interlocks)
Never touch live parts or cable connections of the
●
adjustable frequency drive after it has been
disconnected from the power supply. Due to the charge
in the capacitors, these parts may still be live after
disconnection. Fit appropriate warning signs
