INSTALLATION
For installation in a restricted access location only. Reference Articles
110-8 and 110-18 of the NEC and Section 12 of the CEC.
WARNING: Do NOT connect Power Supply Module to DC power
before installing in Media Conversion Center. Failure to observe this
warning could result in equipment damage and/or personal injury or
death.
CAUTION: Wear a grounding device and observe electrostatic discharge
precautions when setting Master/Slave configuration switch and when
installing Power Supply Module in Media Conversion Center. Failure to
observe this caution could result in damage to, and subsequent failure
of, Power Supply Module.
NOTE: A 15A maximum circuit breaker must be provided as part of
the building installation.
Set Master/Slave Switch, if Applicable
1.
Determine if Master/Slave switch is installed on Power
Supply Module.
NOTE: If Master/Slave switch is installed on ANY Power
Supply Module installed in chassis, ensure that AT LEAST
ONE Power Supply Module in the E-MCC-1600 chassis
is configured as the primary (master) Power Supply
Module.
2.
Set Master/Slave switch, if necessary.
To configure the Power Supply Module as the primary
(master) Power Supply Module, set Master/Slave switch
to position labeled “MASTER”.
To configure the Power Supply Module as the secondary
(slave) Power Supply Module, set Master/Slave switch to
position labeled “SLAVE”.
Install 48V Power Supply Module in Chassis
1.
Locate Power Supply Module installation slot on Media
Conversion Center chassis back.
2.
Remove Power Supply Module protective plate from
installation slot by removing and retaining two (2) screws
that secure protective plate to back of Media Conversion
Center chassis.
3.
Carefully slide 48V Power Supply Module into Media
Conversion Center installation slot, aligning Power
Supply Module with installation guides.
NOTE: Ensure that the 48V Power Supply Module is
firmly seated against the chassis backplane.
4.
Carefully install two (2) screws (retained in Step 2)
through Power Supply Module into Media Conversion
Center, rotating clockwise to secure.
Connect to Power
CAUTION: Ensure that power source is NOT powered and that 48
VDC power ON/OFF switch is set to “O” when connecting to
Power Supply Module. Failure to observe this caution could result in
damage to, and subsequent failure of, Power Supply Module.
1.
Connect +48 VDC terminal to Media Conversion Center
terminal block control marked “+”. Turn terminal screw
clockwise to secure.
2.
Connect -48 VDC terminal to Media Conversion Center
terminal block control marked “-”. Turn terminal screw
clockwise to secure.
3.
Connect ground terminal to Media Conversion Center
terminal block control marked “chassis ground”. Turn
terminal screw clockwise to secure.
4.
Set 48 VDC Power Supply Module power switch to “I”.
