Notes on the power supply 100 to 240 VAC
Connect and disconnect the power supply unit only when it is not energized
The PS598-1 power supply unit is not capable of hot plugging. Connecting or disconnecting
the PS598-1 when the 100 to 240 VAC power supply is on can damage the PS598-1 power
supply unit and the IE switch.
Before connecting or disconnecting the PS598-1 power supply unit, make sure that the
switch for the input voltage (position
) is set to position "0".
The fuses FUSE1 and FUSE2 are in the fuse holder (position ②). The fuses are of the type
F6.3AH / 250 VAC.
Overvoltage protection for the power supply cables
If there is any possible overload of the power supply cables, suitable overvoltage protection
is necessary. Refer to the values on the type plate.
Reliable grounding of the devices mounted in the rack must be guaranteed. This applies, in
particular, to power supply cables that are not connected directly to the power supply
circuit. With the PS598-1 power supply unit, the IEC power connector (IEC 60320-1)
provides the connection to protective earth.
