[7.C2] Protective Earth Resistance R; Pe Measurement; [7.C3] Isolation Resistance R; Iso Measurement - h/p/cosmos 150/50 locomotion de med Operating Instructions And Service Manual

N
Clean device and engine compartment/internal space. Remove dust and dirt from the cooler openings of the
fan housing and the cooling air ducts of the drive motor, as well as from the ventilation slots and the cover of
perforated plate of the frequency inverter.
N
Attach hazard notes completely and well legible according to the instructions. Check the warning signs,
protective covers, step platform, engine hood and plastic-cover installation channel in the engine compartment
for existence and for damage and replace as necessary.
N
All protective-resistance connectors, which can be reached from the outside, must examined for their correct
value and correct labelling.
N
Check capture slot at the rear end and at reverse belt rotation in the front as well and adjust as necessary.
Capture slot < 8 mm. According to regulation draft 60601-2-xx © IEC:200X 62D/479/NWIP 2003-05-18 and
according to EN 957-1:2005. See chapter "test-finger".

N
Resistance between housing and ProtectiveEarth-
Connection.
N
The low resistance pass is to be controlled according to
VDE 0701/0702 (sports and fitness machines) or VDE
0751/IEC 601-1 (medical devices) by the protective-
resistance measurement with a measuring device for the
protective-earth-resistance measurement.
N
The connecting lead is to be moved while measuring for
at least 5 sec. If the resistance changes hereby it is highly
probable that the cable or the connectors have been
damaged. In this case the cable has to be replaced and
the device has to be repaired immediately.
N
Resitance between „briged" L+N and ProtectiveEarth-
Connection.
N
Make sure that all isolations, that are under stress of the
mains voltage, are being seized. All switches and
contactors should be connected.
N
The measuring is to be performed with measuring
devices for the isolation-resistance measurement
according to VDE 0701/0702 (sports and fitness
machines) or VDE 0751/IEC 601-1 (medical devices).
