Chapter 2 Installing the Monitor
3. Hard wire the AC power by using the provided AC power cord (3).
Verify that the power cord is firmly secured to the AC power adapter by
the metal cage already attached to the adapter (
4).
4. Restore AC power.
Connect DC Power
The monitor connects to a 9…36V DC power source through a DC input
terminal block. The DC power option supports operation from either a safety
extra-low voltage (SELV) or protective extra-low voltage (PELV) power source.
The power supply is internally protected against reverse voltage polarity.
Follow these steps to connect power to the monitor.
1. Turn off the main power switch or breaker.
2. Route the power wires from your DC power supply and connect the leads
to the DC input terminal block on the monitor.
The monitor does not require a ground connection to meet any regulatory
compliance when connecting DC power.
ATTENTION: Use a SELV isolated and ungrounded power supply as input
power to the monitor. This power source provides protection so, under
normal and single fault conditions, the voltage between the conductors
and functional earth/protective earth does not exceed a safe value.
IMPORTANT Do not use the AC adapter and external DC at the same time.
