Connect Line Power Wiring
ERn enclosures are available in 100-120, 230 CE, and 240 VAC single phase
configurations. The ERn enclosure requires a single phase, 20 amp (maximum) at 120 VAC
input feed or a 15 amp (maximum) at 230 and 240 VAC. The two-wire hot and neutral
terminates to the power input terminal block (top left) and a ground wire terminates to the
ground bar.
Step 1:
Pull the line, neutral, and ground cables to the enclosure through the conduit
openings previously prepared.
Step 2:
Insert the ground wire into a screw terminal on the ground terminal block and
secure.
Step 3:
Insert the neutral wire into the neutral screw terminal on the power input terminal
block and secure.
Step 4:
Insert the line (input feed) into the line screw terminal on the power input terminal
block and secure.
W A R N I N G :
All rack terminations must be done with the power off. Racks installed
without an accessible power disconnect device cannot be serviced or
operated safely.
