Safran SecureSync 2400 - Page 70

DANGER! GROUNDING: SecureSync is earth grounded through the
24/48V
DC
3-Pin power connector. Ensure that the unit is connected
to a DC power source that is connected to earth ground via the
grounding pin C of the SecureSync DC power plug supplied in the
ancillary kit.
A DC power connector to attach DC power to SecureSync is included in the ancil-
lary kit provided with the equipment. A cable of 6feet or less, using 16AWG wire,
with adequate insulation for the DC voltage source should be used with this con-
nector. The cable clamp provided with the DC power plug for strain relief of the
DC power input cable should be used when DC power is connected to
SecureSync.
DC power- +12 V and +24/48 V identification
To eliminate confusion, the two different voltages for DC power use different con-
nectors. The DC connectors are identical between the fixed or hot-swappable ver-
sions.
The +12 V
DC
power supply uses a 2-pin connector and has a 12 V label, either
above the input or on the body of the power supply module (for Hot Swap mod-
els). The connector is keyed to prevent incorrect insertion.
The +24/48V
DC
power supply uses a 3-pin connector and has a 24/48 V label,
either above the input or on the body of the power supply sled (for Hot Swap
models). This connector is also keyed to prevent incorrect insertion.
