Safety information for the internal
power supply and the dual-redundant
PSU
Risk of electrical shock

Do not open the cover of the internal power supply or
dual-redundant PSU.
There are no user-serviceable parts inside.

When using the service cable to power a module, do not
open the voltage selector or attempt to change the voltage
of that module.
Risk of damage to equipment

In the internal power supply, each daisy-chain cable is
protected by an 8 A fuse. Do not overload the cables.

The internal power supply can supply up to 200 W to a
single daisy-chain, or up to 250 W across two daisy-chains.
Do not overload the internal power supply. If the internal
power supply is overloaded, it will not start.

The dual-redundant PSU can supply up to 350 W to a
single daisy-chain, or up to 450 W across two daisy-chains.
Do not overload the dual-redundant PSU. If the
dual-redundant PSU is overloaded, one or both power
units can fail.
If a single power unit fails, and the dual-redundant PSU is
still overloaded, the other can fail soon afterward.

Do not block the vents of the internal power supply or
dual-redundant PSU. If a power supply overheats, it shuts
down and will not restart.

Before you connect the service cable to a module, make
sure the connector is up the right way.
