2.4.3 -48V DC Power Supply/Cooling Module Procedure
Important
PSU2 (RH rear bay) must be fitted “upside-down” as shown in
Figure 2–1
. If the cable strain relief
wire tab is upside down it must be inverted by squeezing together the two sides of the tab
removing them from their mountings, inverting and then replacing them.

-48V DC PSU Safety Requirements
Voltage Rating
The marked rated voltage for the-48VDC Power Supply/Cooling (PSU) module is -40V DC to -60V DC.
The equipment is intended to operate from a centralized dc supply system with a NOMINAL voltage of -
48V DC or -60V DC.The voltage from a nominal -48V DC system may vary, due to float charging or
discharge conditions, from -40V DC to -60V DC.The voltage from a nominal -60V DC system may vary,
due to float charging or discharge conditions, from -48V DC to -72V DC.
Caution
If this equipment is used in a manner not specified by the manufacturer, the protection provided by the
equipment may be impaired.
Equipment Location
The rear of this Equipment (in particular the supply terminals and wiring to the terminals on the power
supply) must only be located in a “
