2 Safety
instructions
2.1 Symbol
description
These symbols are used to warn against potential safety hazards or causes of
damage or provide useful information.
Hazard warning
This symbol appears in the operating instructions next to all instructions relating to
safety at work wherever a potential danger to life and limb exists.
Follow these instructions at all times and be particularly vigilant and cautious.
Pass on safety instructions to all persons entrusted with working on the product
including the power supply.
In addition, observe all general safety regulations at all times.
Warning against dangerous electrical voltage
Contact with live parts can result in immediate death. Protective covers (e.g.
covers and enclosures) marked with this sign may only be opened by qualified
electricians. Before opening, all relevant operating, control, feed or other voltages
must be disconnected.
Operating hazard for the installation
This symbol in the operating instructions indicates all warnings which, if not
complied with, may result in damage to the product.
The DRC-10 hand-held transmitter is intended to be used as an operating unit and
transmitter station for the DRC-DR and DRC-MP radio receivers. The scope of
functions is preferably designed for wireless control of crane installations, travelling
hoist units, chain and rope hoists, transfer carriages and similar applications.
The operator can position himself as required. He can control loads and move-
ments from a safe distance. He must always select a location to ensure that
all movements of the load and the crane can be monitored and any hazardous
movement can be switched off within an appropriate time. Before starting a crane
movement by actuating the operating element, the operator must determine which
crane is being controlled. The display of the DRC-10 hand-held transmitter shows
the identification/crane number of the controlled crane. The radio-controlled crane
must be identified by means of the identification/crane number in a way clearly
visible to the operator.
If required, a signal must be actuated prior to a crane movement for acoustic
control.
