• Carry out the postinstallation checks described in Section 3.17 to
Section 3.19 of this manual.
• Program a series of
unit
e
features, which are necessary in
order for
e
maGEN
to operate, following the programming
instructions in Section 19 of this manual.
WARNING
You should install an AC surge protector to
protect the
e
maGEN
-PC against power
fluctuations. Install the surge protector
before setup and test procedures are car-
ried out. Use of a UPS is also recom-
mended.
3.11 POWER CABLING
1. Before installing
e
maGEN
, inspect all wiring and electrical out-
lets for proper grounding and voltage.
• Be sure the third wire power ground connects to the building
input transformer or driven ground rod.
• Voltage measurements between the black wire (measured
from the smaller of the two slots on an outlet) and third wire
ground should equal 117VAC ± 10%.
2. In areas where electrical storms pose a danger, install a tran-
sient AC protection device in the power lines. This is particularly
important where power is provided by outside overhead lines.
Install a transient AC protection device if the system is installed
in a manufacturing area where motor driven machinery, com-
pressors, pumps, elevators, or other periodically operating units
are installed.
3. Protect the equipment against accumulated static electricity
which can damage sensitive electronic circuitry in the cabinet. If
the site is at high altitude or in a dry climate, humidifying the
area may be necessary to correct static electricity problems.
3.12 MAIN DISTRIBUTION FRAME (MDF) CROSS CONNECTS
Connecting
e
maGEN
to a telephone system is similar to connecting
individual single-line sets. The
e
maGEN
system ports require two-
wire modular line cords. Each jack on the telephone interface card
connects two ports (RJ-11 type connector).
