Alternate Disconnect Recommendation
The ON/OFF switch on the front of the system DOES NOT remove power
from the rack.
Mains Disconnect
A mains disconnect for emergency purposes can be as simple as unplugging
the power cord from the power source receptacle. The receptacle and power
cord plug must be easily accessible to use this method for emergency power
shut-down. Use the optional emergency disconnect switch described below
if you require an emergency power off feature.

Disconnect Switch
Recommendation
Emergency power off (EMO) capability is not provided with the Filtered
Power Strip. An external mains disconnect switch or breaker should be
installed adjacent to the equipment for easy access. Usual mounting is an
approved enclosure on a floor-mounted pedestal. If an external emergency
off (EMO) is required, it should be installed by a qualified electrician and
comply with the following:
•
Rated for the maximum system amperage (15/16 Amp).
•
Approved for use in building installations in your locality.
•
Marked "Emergency OFF" or the equivalent in your local language.
•
"Off" position clearly marked.
•
Capable of locking in the "Off" position, but not in the "On" position.
•
Capable of opening all phases and neutral conductors, but not the
safety grounding conductor.
