Line Power Wiring
Non-Intrinsically Safe Wiring
Always lock out and tag electrical
circuit breakers while installing or
servicing this equipment and any
related equipment. A potentially
lethal electrical shock hazard and
the possibility of an explosion or re
from a spark can result if the electrical
circuit breakers are accidentally turned
on during installation or servicing.
Power to the console must be 110 to 240 V~, 50 / 60 Hz.
At the electrical power panel, use a 20 amp circuit breaker
used only to supply power to the Colibri console.
Note: Do not connect other equipment to this circuit.
Figure 4: Power Wiring Connection
The ground bus in the electrical panel must be
connected to an earth ground as required by the
National Electrical Code (or Canadian Electrical Code)
when applicable. If the ground bus is not properly
connected to an earth ground or if the IS safety ground
is not properly connected at the console, a dangerous
condition will be created which could result in an
explosion.
Check Electrical Resistance to Earth Ground
After wiring the IS safety grounds, check the resistance
between the IS safety ground terminals at the console and
the earth ground – this resistance must be less than 1 ohm.
