7. Please note that the adjustable frequency drive has more voltage sources than L1, L2 and L3, when load sharing (linking of DC intermediate
circuit) or external 24 V DC are installed. Make sure that all voltage sources have been disconnected and that the necessary time has elapsed
before commencing repair work.
2.1.3 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.
Using VLT®AutomationDrive FC 300: wait at least 15 minutes.
Shorter time is allowed only if indicated on the nameplate for the specific unit.
Leakage Current
The ground leakage current from the FC 300 exceeds 3.5 mA. To ensure that the ground cable has a good mechanical connection to
the ground connection (terminal 95), the cable cross-section must be at least 0.016 in2[10 mm2] or 2 times rated earth wires terminated
separately.
Residual Current Device
This product can cause a DC current in the protective conductor. If a residual current device (RCD) is used for extra protection, only
an RCD of Type B (time delayed) may be used on the supply side of this product. See also RCD Application Note MN.90.GX.02.
Protective grounding of the FC 300 and the use of RCDs must always follow national and local regulations.
NOTE!
For vertical lifting or hoisting applications it is strongly recommended to ensure that the load can be stopped in case of an emergency
or a malfunction of a single part such as a contactor, etc.
If the adjustable frequency drive is in alarm mode or in an overvoltage situation, the mechanical brake cuts in.
2.1.4 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
2.1.5 Avoid Unintended Start
While the FC 300 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 FC 300 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 supply, or lost motor connection may cause a stopped motor to start. The FC 300 with
Safe Stop (i.e., FC 301 in A1 enclosure and FC 302) provides protection against unintended starts if the Safe Stop Terminal 37 is on low voltage
level or disconnected.

2.1.6 Safe Stop of the FC 300
The FC 302, and also the FC301 in A1 enclosure, can perform the safety function Safe Torque Off (as defined by IEC 61800-5-2) or Stop Category 0 (as
defined in EN 60204-1).
FC 301 A1 enclosure: When safe stop is included in the drive, position 18 of Type Code must be either T or U. If position 18 is B or X, Safe Stop Terminal
37 is not included!
Example:
Type Code for FC 301 A1 with Safe Stop: FC-301PK75T4Z20H4TGCXXXSXXXXA0BXCXXXXD0
It is designed and deemed suitable for the requirements of Safety Category 3 in EN 954-1. This function is called safe stop. Prior to integrating and using
safe stop in an installation, a thorough risk analysis must be carried out on the installation in order to determine whether the safe stop functionality and
safety category are appropriate and sufficient. 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
contained in the Instruction Manual are not sufficient for a correct and safe use of the safe stop functionality!

2.1.7 Safe Stop Installation - FC 302 only (and FC 301 in frame size A1)
To carry out an installation of a Category 0 Stop (EN60204) in
accordance with Safety Category 3 (EN954-1), follow these in-
structions:
1. The bridge (jumper) between Terminal 37 and 24 V DC must be
removed. Cutting or breaking the jumper is not sufficient. Re-
move it entirely to avoid short-circuiting. See jumper on illus-
tration.
2. Connect terminal 37 to 24 V DC by a short circuit-protected ca-
ble. The 24 V DC voltage supply must be interruptible by an
EN954-1 category 3 circuit interrupt device. If the interrupt de-
vice and the adjustable frequency drive are placed in the same
installation panel, you can use a regular cable instead of a pro-
tected one.
3. The Safe Stop function only fulfills EN 954-1 Category 3 if it is
protected by an enclosure with protection class IP 54 or higher.
Therefore, FC 302s, with a protection class lower than IP54,
must be mounted inside a housing (cabinet) that provides IP54
protection. FC 302s with protection class IP54 or higher need no
further protection. FC 302 A1 is only delivered with an IP21 en-
closure and must therefore always be mounted in a cabinet.
Figure 2.1: Bridge jumper between terminal 37 and 24 VDC
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.
Figure 2.2: Illustration of the essential aspects of an installation to achieve a Stopping Category 0 (EN 60204-1) with safety Category 3 (EN
954-1).
2.1.8 IT Line Power
Par. 14-50 RFI 1 can be used to disconnect the internal RFI capacitors from the RFI filter to ground in the 380-500 V adjustable frequency drives. If this
is done, it will reduce the RFI performance to A2 level. For the 525-690 V adjustable frequency drives, par 14-50 has no function. The RFI switch cannot
be opened.

3.3 Electrical Installation
NOTE!
Cables General
All cabling must comply with national and local regulations on cable cross-sections and ambient temperature. Copper (140°–167°F
[60°–75°C]) conductors are recommended.
Aluminum Conductors
Terminals can accept aluminum conductors, but the conductor surface must be clean, and the oxidation must be removed and sealed by neutral acid-
free Vaseline grease before the conductor is connected.
Furthermore, the terminal screw must be retightened after two days due to softness of the aluminum. It is crucial to keep the connection a gas-tight
joint, otherwise the aluminum surface will oxidize again.

3.3.1 Removal of Knockouts for Extra Cables
1. Remove the cable entry from the adjustable frequency drive (this prevents foreign parts from falling into the adjustable frequency drive when
removing knockouts)
2. The cable entry must be supported around the knockout you intend to remove.
3. The knockout can now be removed with a strong mandrel and a hammer.
4. Remove burrs from the hole.
5. Mount cable entry on adjustable frequency drive.
3.3.2 Connection to Line Power and Grounding
NOTE!
The plug connector for power is plugable on adjustable frequency drives up to 10 hp [7.5 kW].
1. Insert the two screws into the de-coupling plate, slide it into place and tighten the screws.
2. Make sure the adjustable frequency drive is properly grounded. Connect to ground connection (terminal 95). Use the screw from the accessory
bag.
3. Place plug connector 91 (L1), 92 (L2), 93 (L3) from the accessory bag onto the terminals labeled MAINS at the bottom of the adjustable frequency
drive.
4. Attach the line wires to the line power plug connector.
5. Support the cable with the enclosed supporting brackets.
NOTE!
Ensure that AC line voltage corresponds to the AC line voltage on the nameplate.
IT Line Power
Do not connect 400 V adjustable frequency drives with RFI filters to line power supplies with a voltage between phase and ground of
more than 440 V.
The ground connection cable cross-section must be at least 0.016 in2[10 mm2] or 2 x rated line power wires terminated separately
according to EN 50178.
The AC line input connections are fitted to the line switch if this is included.
