Residual risk, dangerous zone
and person exposed
Course of action to eliminate or reduce risk
Sudden start owing to the insertion
of the plug into a normal socket.
Do not insert the hoist power plug directly into a CEE socket. The
hoist may only be powered using suitable control devices, such as
EXE-DRIVE controllers. For low voltage controlled hoists, a
dedicated controller must be used with an UP/DOWN push-button
panel that complies with the wiring diagram provided.
Various types of risks owing to
tampering or removal of the safety
devices.
It is prohibited to tamper or remove the safety devices
Table 1
: “Residual risks”
2.6 SAFETY WARNING FOR ELETRICAL CONNECTION
Before a hoist is connected to its control device the power supply shall be checked for correct voltage.
A fluctuation of +/- 10% is allowed. In order to prevent a voltage drop, the user should ensure there is the
minimum number of connections as possible in any power cable run.
Keep length of power cables as short as possible (see table below) and remove corrosion on the contacting
pins of the electrical connectors as it might lead to a voltage drop.
In order to minimize the voltage drop between the power source and the hoist the following cable lengths
shall be used as maximum (see
Table 2
).

EXE-Rise Models are explained in paragraph 3.2
Table 2 “Relation between power and lengths of cable”
The electrical power plug must be disconnected from the power supply of the hoist in case of maintenance or
emergency.
Dangerous voltage drop can be caused by using excessively long extension cables as well as by
overheating the wire.
