3.3 AC POWER CONNECTION
WARNING – Electrical Shock Hazard
Disconnect power to the AC mains before making or removing any electrical
connections to the monitor.
A proper earth ground connection must be made to the copper lug with the
ground symbol on the chassis. Failure to do so may result in a shock hazard
and malfunction of the monitor.
3.3.1 WIRING REQUIREMENTS FOR NEMA ENCLOSURES
Use appropriate wiring rated for this type of equipment, ensuring that it meets local
and national safety and building requirements.
Ensure that overcurrent protection is used on AC mains connections (a 5 A circuit
breaker is recommended), and that it fulfills the following requirements:
•
be located as near to the instrument as possible
•
quickly and easily accessible
•
clearly labeled as the disconnecting device for this instrument
3.3.2 WIRING INSTRUCTIONS
For the NEMA configuration, the electrical connection must be hard-wired to the
terminal block and grounding lug on the chassis. AC power connection to the
monitor should be made with 12-14 AWG copper wire, connected to the monitor as
follows:
•
Earth Ground (green):
Connect the earth ground wire to the copper grounding lug
•
Line (Black):
Connect the Line wire to the terminal block directly across
from the black wire that leads to the power supply
•

across from the white wire that leads to the power supply.
