Specifications

Note
Some European markets use the 887B power controller which is
electrically the same as the 881B although its physical configuration
is slightly different.
Complete safety and tag-out procedures are explained in the Digital safety
courses listed in Table 1. For maximum safety, always use the following tag-out
procedures:
• Turn off site power at the main circuit breaker.
• Place a tag-out tag on the circuit breaker.
• Connect the power controller power cord to the outlet.
• Turn on site power at the main circuit breaker when you have finished with
the installation.
• Remove the tag-out tag.
• Connect the power controller power cord to the outlet and turn it on.
• Turn on all components in the cabinet.
Figure 3–19 shows the 881 power connector configurations and specifications.
