It is not permitted to disable the protection system by using extension cables not equipped with a
protection earth conductor.
Caution:
Any interruption of the protection earth conductor within the EcoDrive or outside, or by
disconnecting the protection earth connection, can result in making the equipment
hazardous.
Any intentional interruption is inadmissible.
Fault Current Protection Devices
If any EcoDrives are to be monitored via fault current protection devices, then the latter must be shock
puls proof, short pulse delayed as well as suited for alternating and pulsating constant fault currents.
For connections, use line types not lighter than plastic- insulated sheathed flexible cables H05 VV.
The minimum conductor cross section must be 1 mm
2
, with the line length not in excess of 5 m.
The voltage drop in the protection earth conductor is not permitted to exceed 3.3 V at a measuring
current of 10 amps.
Any lines installed must be properly protected against anticipated loads and must be properly fastened.
Place and attach lines so as to maintain a minimum distance of 25 mm relative to any moving parts.
Place lines, mains power leads and low voltage circuits at a proper distance from each other to achieve
adequate separation.
For replacement make sure to use exclusively fuses of the type and current rating specified.
Any bridging-over of fuses is inadmissible and will create electrical or fire hazards.
If there is reason to presume that operation without hazards will not be possible, discontinue operation of
the drive system and safeguard the equipment against inadvertant use.
Reasons to presume that operation without hazards will not be possible are as follows:
-
if the drive system presents visible damage, for instance mains power connection cable,
-
if the drive system fails to function,
-
after lengthy storage at unfavourable conditions.
The control box may be opened only by properly qualified personnel and after having separated the drive
system from mains power by pulling the plug out. (After switching the system off, wait at least 10
minutes.)
Insert and lock carefully the connectors on the control system after having checked the pin and socket
configuration and the plug-in direction, to avoid malfunction.
The brake action will not be initiated when mains power supply is switched off or power failure occurs
during operation of the EcoDrive.
When leaving the workplace or when doing maintenance work, separate the machine from
mains power by pulling out the plug. For this, do not pull at the cable, but grip the plug and pull it
out.
Before separating the EcoDrive from mains power,
bring all control elements into „OFF“ or „0“ position.
