GE Industrial Solutions AF-650 GP General Purpose Drive (460_575_690V 125HP and above) - Manual (Page 9)

Installation in high altitudes
380 - 500 V: At altitudes above 3 km, please contact GE regarding PELV.
525 - 690 V: At altitudes above 2 km, please contact GE regarding PELV.
2.1.2 Safety Instructions
• Make sure the frequency converter is properly connected to earth.
• Protect users against supply voltage.
• Protect the motor against overloading according to national and local regulations.
• Motor overload protection is not included in the default settings. To add this function, set par. F-10 Electronic Overload to value Elec. OL trip or Elec. OL
warning. For the North American market: Electronic Thermal Overload functions provide class 20 motor overload protection, in accordance with NEC.
• The earth leakage current exceeds 3.5 mA.
• The [OFF] key is not a safety switch. It does not disconnect the frequency converter from mains.
2.1.3 General Warning
Warning:
Touching the electrical parts may be fatal - even after the equipment has been disconnected from mains.
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 back-up.
When using the frequency converter: wait at least 40 minutes.
Shorter time is allowed only if indicated on the nameplate for the specific unit.
Leakage Current
The earth leakage current from the frequency converter exceeds 3.5 mA. To ensure that the earth cable has a good mechanical connection
to the earth connection (terminal 95), the cable cross section must be at least 10 mm 2 or 2 rated earth wires terminated separately. For proper
earthing for EMC, see section Earthing in the How to Install chapter.
Residual Current Device
The drive can cause a D.C. 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.
Protective earthing of the frequency converter and the use of RCD's must always follow national and local regulations.
2.1.4 Before Commencing Repair Work
1. Disconnect the frequency converter from mains
2. Disconnect DC bus terminals 88 and 89 from load share applications
3. Wait for 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 frequency converter is connected to mains, the motor can be started/stopped using digital commands, bus commands, references or via the
keypad::
• Disconnect the frequency converter from mains whenever personal safety considerations make it necessary to avoid unintended start.
• To avoid unintended start, always activate the [OFF] key before changing parameters.
• An electronic fault, temporary overload, a fault in the mains supply, or lost motor connection may cause a stopped motor to start. The frequency converter
with Safe Stop provides protection against unintended start, if the Safe Stop Terminal 37 is deactivated or disconnected.
