Safety Warnings
SEE INSTALLATION INSTRUCTIONS BEFORE CONNECTING TO THE SUPPLY!
The exclamation point within a triangle is intended to warn the operator or
service personnel of operation and maintenance factors relating to the
product and its operating environment which could pose a safety hazard.
Always observe standard safety precautions during installation, operation and maintenance of this
product. Only a qualified and authorized service personnel should carry out adjustment, maintenance
or repairs to this instrument. No adjustment, maintenance or repairs should be performed by either the
operator or the user.
Telecommunication Safety
1. The unit should be installed within 1.5m (5 feet) of a grounded, easily accessible AC outlet, or in
an adequately earthed rack mount. If the protective earth connection is not guaranteed by the
mains supply, the unit must be externally connected to a reliable protective earth. DC powered
units must be connected only to power sources which conform to the relevant safety standard.
2. In order to guarantee an uninterrupted flow of air stream, leave at least 15 mm spacing above
and below the top and bottom sides of the unit. The recommended maximum temperature of the
surrounding area is 40°C.
3. Vacant slots must always be covered with blank covers. This is necessary in order to guarantee a
definite cooling stream of air and to prevent unintentional and unauthorized access inside the
equipment.
4. The safety status of the ports on the LRS-24 is declared according to EN 41003 and is detailed in the
table below. Interconnection of these ports with other apparatus should be made so that the
equipment continues to comply with the requirements of EN 60950 connection of SELV and TNV
circuits to other circuits after such a connection is made.
