N0130943 02 Modular ICS 7.1 Installer Guide
Planning the installation
Only qualified persons should service the system.
The installation and servicing of this unit is to be
performed only by service personnel having
appropriate training and experience. It is critical that
installers have the necessary awareness about
hazards to which they are exposed in performing a
task, and of the measures required to minimize the
danger to themselves or other persons.
Electrical shock hazards from the telecommunication
network and AC mains are possible with this
equipment. To minimize risk to service personnel and
users, the ICS must be connected to an outlet with a
third-wire ground. In addition, all unused slots should
have filler faceplates installed and the doors should be
in place at the completion of any servicing.
Service personnel must be alert to the possibility of high
leakage currents becoming available on metal system
surfaces during power line fault events near network
lines. A risk point on the ICS is the power cord earth
ground pin. These leakage currents normally safely
flow to Protective Earth ground via the power cord.
Therefore, it is mandatory that connection to a
grounded outlet is performed first and removed last
when cabling the unit. Specifically, operations requiring
the unit to be powered down must have the network
connections (central office lines) removed first.
