1.10 Fuses
This product is a switching mode power supply. The fuse installed inside
should not break under normal operation. In case the fuse is blown, it may
indicate a malfunction in the unit. In this event, contact B&K Precision.
Warning:
Any disassembling of the casing or changing the fuse not
performed by an authorized service technician will void
the warranty of the instrument.
1.11 Warm-up Time
The XLN series is fully operable upon switching the power on. However, to
reach the specified equipment accuracy, please allow the supply to warm up
for at least 15 minutes.
1.12 Power-off Procedure
When the supply is not in use, be sure to turn the power switch on the panel
to the OFF position to turn off the power. After the power switch is turned to
the OFF position, the inner fans will still run for approximately 10-15
seconds to carry on the inside electric capacitor discharge process per safety
code requirement. Once the discharge process is complete, this product will
carry out the automatic shut-down process.
1.13 Caution

or malfunction.
B. While in parallel connection mode, the output voltage of each power
supplies should be set to equal values. If the setting value of each unit is
not the same, the higher output voltage will feed back to the smaller unit
and damage its internal components.
C. When the AC input voltage is lower than the full-load voltage which is
100 VAC, the supplies will activate an inner overtemperature protector
and cut off the output in response to the condition. To ensure that the
entire test process can be completed smoothly, confirm that the input AC
