OBSERVE THE FOLLOWING ADMONISHMENTS
Danger: INSTALLERS MUST FOLLOW APPROVED SAFETY PROCEDURES.
This system operates from AC voltage capable of producing fatal
electrical shock. AC input power must be completely disconnected from
the branch circuits wiring used to provide power to the system before any
electrical connections are made. DO NOT apply AC power to the system
until all electrical connections have been completed and checked.
This system may also require battery to be connected. Although battery
voltage is not hazardously high, the battery can deliver large amounts of
current. Exercise extreme caution not to inadvertently contact or have
any tool inadvertently contact a battery terminal or exposed wire
connected to a battery terminal. NEVER allow a metal object, such as a
tool, to contact more than one termination at a time, or to simultaneously
contact a termination and a grounded object. Even a momentary short
circuit can cause explosion and injury. Remove watches, rings, or other
jewelry before connecting battery leads. Make the DC (battery)
connections last. Make all other electrical connections
without
Danger: This product requires Safety Extra-Low Voltage (SELV) Inputs. A SELV
input (based on the safety requirements for Information Technology
Equipment Standards, such as UL1950, IEC 950) is a secondary circuit
which is so designed and protected that under normal and single-fault
conditions, the voltage between any two paths of the SELV circuit or
circuits and for Class 1 equipment (provided with a protective earthing
conductor from the building), between any one such part and the
equipment protective earthing terminal does not exceed a safe value (42.4
V peak or 60 Vdc under normal conditions). It is separated from the
primary or mains supply by Double (insulation comprising both Basic and
Supplementary insulation) or Reinforced insulation (a single insulation
system which provides a degree of protection against electric shock
equivalent to Double insulation).
DC input
power applied to the system.
Danger: To minimize voltage potentials inside the bay during installation, connect
leads to the bay first, before connecting leads to the external source.
This includes making connections to any LMS Input/Output (I/O) circuit
card.
