Powering on the NK-IPS
Each NK-IPS is powered by a +15V DC external power supply. This can be either an NK-RP1 power supply which
is shipped as standard or an NK-RP1/NK-RPN1 redundant power supply purchased as an option.
For redundancy, each power cord should be connected to a separate power source for protection against failure of
the A/C power circuit. In the event of one power supply failure, the panel load is seamlessly transferred to the other
connected redundant power supplies.
To connect the power cables to the NK-IPS
1. Connect the male end of the provided power cable into the socket marked POWER .
Figure 4.3 NK-IPS — Power Connection
2. Connect the supplied AC power cable into the power module.
3. Connect the supplied power cable to Mains Power.

ground connector must be connected to an earthed ground.
Warning
— In some countries it may be necessary to supply the correct mains supply cord. Use only
certified cords for the country of use.
