Apply Power to the “redundant twister”
Power is provided to the “redundant twister” from the desktop, universal
input, switching power modules. Each universal power supply module
provides a DC jack for connection of the desktop switching power supply
module. The power modules are equipped with S760 hollow-type plugs
and standard IEC 320-type AC power receptacles.
IMPORTANT: When making power connections, connect the DC power
cord to the DC input jack located on the back panel before making the
connection to the outlet. Failure to do this properly can damage the
product and void the unit’s warranty.
If a redundant power supply module is being used, simply connect the
individual power cords to separate power sources.
A convenient bracket provides strain relief from the weight of the cords to
eliminate an accidental disconnection.
The “redundant twister” does not have a power switch. After connecting
the unit to the AC receptacle, verify that the PWR (power) LEDs illumi-
nate. A steady green light indicates the unit is receiving power. There is
one LED for each power supply. They are labeled A and B.
