Configuration
Before using the power supplies in parallel, the
master and slave units need to be configured.
Steps
1. Configure the OVP and OCP
settings for the master unit.

2. For each unit, hold the Function
key while turning the power on to
enter the power on configuration
settings.

Note
Configuration settings can be checked for both the
master and slave units by pressing the Function
key and checking F-93.
Only the Master OVP and OCP level is used for
over voltage and current protection. Slave OVP and
OCP level is disregarded.
OTP works independently for each unit.
