2.1.1 Disposal Instructions
Equipment containing electrical components may not be disposed of together with domestic
waste.
It must be separately collected with electrical and electronic waste according to local and currently valid legislation.
Caution
The adjustable frequency drive DC link capacitors remain charged after power has been disconnected. To avoid the electrical shock hazard, dis-
connect the adjustable frequency drive from line power before carrying out maintenance. Before servicing the adjustable frequency drive, wait the
minimum amount of time indicated below:

2 Safety Instructions and General Warning
2.1.3 Safety Instructions
• Make sure the adjustable frequency drive is properly grounded.
• Protect users against supply voltage.
• Protect the motor against overloading in accordance with national and local regulations.
• Motor overload protection is not included in the default settings. To add this function, set par. 1-90
trip
or
ETR warning
• The ground leakage current exceeds 3.5 mA.
• The [OFF] key is not a safety switch. It does not disconnect the adjustable frequency drive from line power.
2.1.4 General Warning
Warning:
Touching the electrical parts may be fatal - even after the equipment has been disconnected from line power.
Also make sure that other voltage inputs have been disconnected, such as load sharing (linkage of DC intermediate circuit), as well as
the motor connection for kinetic backup.
When using the adjustable frequency drive: wait at least 40 minutes.
Shorter time is allowed only if indicated on the nameplate for the specific unit.
. For the North American market: ETR functions provide class 20 motor overload protection, in accordance with NEC.

Leakage Current
The ground leakage current from the adjustable frequency drive exceeds 3.5 mA. To ensure that the ground cable has a good me-
chanical connection to the ground connection (terminal 95), the cable cross-section must be at least 0.016 in
ground wires terminated separately. For proper grounding for EMC, see section
Residual Current Device
This product can cause a DC current in the protective conductor. Where a residual current device (RCD) is used for extra protection,
only an RCD of Type B (time delayed) shall be used on the supply side of this product. See also RCD Application Note MN.90.Gx.02
(x=version number).
Protective grounding of the adjustable frequency drive and the use of RCDs must always follow national and local regulations.

chapter.
2.1.5 Before Commencing Repair Work
1. Disconnect the adjustable frequency drive from line power.
2. Disconnect DC bus terminals 88 and 89 from load share applications
3. Wait for the discharge of the DC link. See period of time on the warning label.
4. Remove motor cable
2.1.6 Avoid Unintended Start
While the adjustable frequency drive is connected to line power, the motor can be started/stopped using digital commands, bus
commands, references or via the Local Control Panel (LCP):
• Disconnect the adjustable frequency drive from line power whenever personal safety considerations make it necessary to avoid an unintended
start.
• To avoid an unintended starts, always activate the [OFF] key before changing parameters.
• An electronic fault, temporary overload, a fault in the line power supply, or lost motor connection may cause a stopped motor to start. The
adjustable frequency drive with safe stop provides protection against unintended start, if Safe Stop Terminal 37 is deactivated or disconnected.

2 Safety Instructions and General Warning
The FC 302 can perform the safety function
It is designed and approved suitable for the requirements of Safety Category 3 in EN 954-1. This functionality is called Safe Stop. The information and
instructions of the Instruction Manual are not sufficient for a correct and safe use of the Safe Stop functionality! In order to install and use the safe stop
function in accordance with the requirements of Safety Category 3 in EN 954-1, the related information and instructions of the FC 300 Design Guide MG.
33.BX.YY must be followed! The information and instructions of the Instruction Manual are not sufficient for a correct and safe use of the safe stop
functionality!

2.1.8 Safe Stop Installation
To carry out an installation of a Category 0 Stop (EN60204) in conformity with Safety Category 3 (EN954-1), follow these instructions:
1. The bridge (jumper) between Terminal 37 and 24 V DC must be removed. Cutting or breaking the jumper is not sufficient. Remove it entirely
to avoid short-circuiting. See jumper on illustration.
2. Connect terminal 37 to 24 V DC by a short circuit-protected cable. The 24 V DC voltage supply must be interruptible by an EN954-1 category 3
circuit interrupt device. If the interrupt device and the adjustable frequency drive are placed in the same installation panel, you can use a non-
shielded cable instead of a shielded one.

The illustration below shows a Stopping Category 0 (EN 60204-1) with safety Category 3 (EN 954-1). The circuit interruption is caused by an opening
door contact. The illustration also shows how to connect a non-safety-related hardware coast.

3.1.1 Planning the Installation Site
3 How to Install
NOTE!
Before performing the installation, it is important to plan the installation of the adjustable frequency drive. Neglecting this may result
in extra work during and after installation.
Select the best possible operation site by considering the following (see details on the following pages and in the respective Design
Guides):
• Ambient operating temperature
• Installation method
• How to cool the unit
• Position of the adjustable frequency drive.
•Cable routing
• Ensure the power source supplies the correct voltage and necessary current.
• Ensure that the motor current rating is within the maximum current from the adjustable frequency drive.
• If the adjustable frequency drive is without built-in fuses, ensure that the external fuses are rated correctly.
3.1.2 Receiving the Adjustable Frequency Drive
When receiving the adjustable frequency drive, make sure that the packaging is intact, and look for any damage that might have occurred to the unit
during transport. If damage has occurred, immediately contact the shipping company to make a damage claim.

3.1.4 Lifting
Always lift the adjustable frequency drive using the dedicated lifting holes. For all D and E2 (IP00) enclosures, use a bar to avoid bending the lifting holes
of the adjustable frequency drive.
Figure 3.2: Recommended lifting method, frame sizes D and E .
NOTE!
The lifting bar must be able to handle the weight of the adjustable frequency drive. See
different frame sizes. Maximum diameter for bar is 1 in [2.5 cm]. The angle from the top of the drive to the lifting cable should be
60° C or greater.

3.2 Mechanical Installation
Preparation of the mechanical installation of the adjustable frequency drive must be done carefully to ensure proper results and to avoid additional work
during installation. Start by taking a close look at the mechanical drawings at the end of this instruction manual to become familiar with the space demands.
3.2.1 Tools Needed
3
To perform the mechanical installation, the following tools are needed:
• Drill with 0.39 or 0.47 in [10 or 12 mm] drill.
• Tape measure
• Wrench with relevant metric sockets (0.28-0.67 in (7-17 mm))
• Extensions to wrench
• Sheet metal punch for conduits or cable connectors in IP 21/Nema 1 and IP 54 units
• Lifting bar to lift the unit (rod or tube max. Ø1 in [25 mm], able to lift minimum 880 lbs [400 kg].
• Crane or other lifting aid to place the adjustable frequency drive in position
• A Torx T50 tool is needed to install the E1 in IP21 and IP54 enclosure types.
3.2.2 General Considerations
Space
Ensure proper space above and below the adjustable frequency drive to allow airflow and cable access. In addition, space in front of the unit must be
considered to allow the panel door to be opened.

Wire access
Ensure that proper cable access is present including the necessary bending allowance. As the IP00 enclosure is open to the bottom cables must be fixed
to the back panel of the enclosure where the adjustable frequency drive is mounted, i.e., by using cable clamps.
NOTE!
All cable lugs/shoes must mount within the width of the terminal bus bar.

Be aware that the power cables are heavy and hard to bend. Give thought to the optimum position of the adjustable frequency drive for ensuring easy
installation of the cables.
NOTE!
All D frames are available with standard input terminals or disconnect switch. All terminal dimensions can be found in the following
table.
