Attaching Power
The KR203 printer has unique power requirements to operate efficiently, safely and within
safety and compliance regulation guidelines. To achieve optimum performance, an
approved power supply should be used to operate the KR203 printer. Refer to "Printer
Power Supply – 808099-004" on page 57.
If a non-Zebra supplied power supply is used with the KR203, it must comply with the
following requirements.
Note • The printer does not have an integrated power switch.

Thermal Allowed, Not Required
Remark:
When Short Circuit Protection or Over Current Protection is activated, the power supply will
shutdown automatically. Once the abnormal condition resulting in the failure being removed, the
power supply will restart accordingly.
Automatic Recovery:
Over Voltage Protection is activated, the power supply will shutdown. The power supply is fully
protected against short circuits and automatically recovers upon removal of the short without the
need for re-cycling the AC input voltage.
