In US installations, the line cord must meet National Electric Code (NEC)
requirements. If you are planning an installation on a non-raised floor, when
line cords are run on the surface of the floor, they must be protected against
physical damage (See NEC 645-5). For other countries, local codes apply.
The zSeries 800 power cords use the following wire colors:
Domestic (supplied with plug)
Line 1 Brown
Line 2 Black
Ground Green/yellow
EMEA, AP, and all others (supplied without plug)
Line 1 Brown
Line 2 Blue
Ground Green/yellow
The maximum permissible CB rating is 20A. In geographic areas where the breaker
sizes given are not available, the standard size circuit breaker giving the closest
higher numerical value of current rating should be used.
It is recommended that a 20A CB for 200-240V be used for each of the two system
power feeds.
There is no requirement for a delayed circuit breaker protecting the AC supply to
the z800, but if you are preparing a new installation site, a delayed circuit breaker is
recommended.
A duplex service tool outlet should be installed within 1.5 m (5 ft) of the system
frame. The power requirement is 110V/120V for USA and Canada (other power
requirements are country dependent). The service tool outlet should be placed on
it's own circuit breaker so it can be used when the processor frame circuit breaker
is off.
There is a unit emergency power off (UEPO) switch on the front of the frame. When
tripped, the UEPO switch will immediately disconnect utility power (AC voltage) from
the machine. All volatile data will be lost.
