2.1.2. High Voltage
The voltage of the adjustable frequency drive is dangerous whenever the adjustable
frequency drive is connected to line power. Incorrect installation or operation of the
motor or adjustable frequency drive may cause damage to the equipment, serious
personal injury or death. The instructions in this manual must therefore be observed,
in addition to applicable local and national rules and safety regulations.
Installation at high altitudes
At altitudes higher than 6,500 ft [2 km], please contact Danfoss Drives regarding
PELV.
The voltage of the adjustable frequency drive is dangerous whenever connected to
line power. Incorrect installation of the motor, adjustable frequency drive or serial
communication bus may cause damage to the equipment, serious personal injury or
death. Consequently, the instructions in this manual, as well as national and local
rules and safety regulations, must be followed.
Safety Regulations
1. The adjustable frequency drive must be disconnected from line power if repair work is
to be carried out. Make sure that the line supply has been disconnected and that the
necessary time has passed before removing motor and line plugs.
2. The [STOP/RESET] key on the control panel of the adjustable frequency drive does not
disconnect the equipment from line power and is thus not to be used as a safety switch.
3. Correct protective grounding of the equipment must be established, the user must be
protected against supply voltage, and the motor must be protected against overload in
accordance with applicable national and local regulations.
4. The ground leakage currents are higher than 3.5 mA.
5. Protection against motor overload is not included in the factory setting. If this function
is desired, set par. 1-90 to data value ETR trip or data value ETR warning.
6. Do not remove the plugs for the motor and line supply while the adjustable frequency
drive is connected to line power. Make sure that the line supply has been disconnected
and that the necessary time has passed before removing motor and line plugs.
7. Please note that the adjustable frequency drive has more voltage inputs than L1, L2 and
L3 when load sharing (linking of DC intermediate circuit) and external 24 V DC have been
installed. Make sure that all voltage inputs have been disconnected and that the neces-
sary time has passed before commencing repair work.

2.1.3. General Warning
Warning:
Touching the electrical parts may be fatal - even after the equipment has been dis-
connected 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.
A 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 in.

] or 2 times rated
ground wires terminated separately.
Residual Current Device
This product can cause 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 meet national
and local regulations.
2.1.4. Before Commencing Repair Work
1. Disconnect the adjustable frequency drive from the line power.
2. Wait for the discharge of the DC link. See the period of time on the warning label.
3. Disconnect DC bus terminals 88 and 89.
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 com-
mands, 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 parame-
ters.
• 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

2.1.7. Safe Stop Installation (FC 302 and FC 301 - A1 enclosure only)
To carry out an installation of a Catego-
ry 0 Stop (EN60204) in accordance with
Safety Category 3 (EN954-1), follow
these instructions:
1. The bridge (jumper) between Termi-
nal 37 and 24 V DC must be re-
moved. 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 inter-
ruptible by an EN954-1 category 3
circuit interrupt device. If the inter-
rupt device and the adjustable fre-
quency drive are placed in the same
installation panel, you can use a reg-
ular cable instead of a protected one.
3. Unless the FC302 itself has protec-
tion class IP 54 and higher, it must
be placed in an IP 54 enclosure. Con-
sequently, FC301 A1 must always be
placed in an IP 54 enclosure.
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.
