3746-900 and service processor installation
Connection to Main Power
Install the 3746-900 close to the 3745 or 3746 frame to avoid any problem later in
routing the cables between the machines.
Power Description and Load Requirements
Note: The following procedures apply to both basic and optional power attach-
ments and must be performed twice if an AC optional power attachment is installed
on the machine. If you received a controller expansion, the customer must
provide a separate 220V ac power receptacle to connect the units installed in the
controller expansion.
Power Attachment Configuration
Basic Attachment: Single Power Supply: The basic attachment is ac connected
to input AC-1 (see Figure B-14 on page B-10).
Optional Attachment: Dual Power Supply Feature: The optional ac attachment
is connected to the input AC-2
There is no internal relation (or connection) between AC-1 and AC-2.
Therefore, AC-2 voltage and frequency can be different from those of AC-1 (see
Figure B-12 on page B-9 or Figure B-13 on page B-9).
Power Requirements
1. Basic AC-1 power input:
The standard voltage input to the 3746-900 is single-phase, 200 to 240 volts 60
Hz, or 200 to 240 volts 50 Hz. The maximum power requirement is 2.5 kVA.
2. Optional AC-2 power input:
Voltage and frequency limits are the same as for AC-1.
Note for World Trade: This product allows connection to an impedance grounded
(impedance "terre" or IT) power system.
(An IT power system is a power distribution having no direct connection to earth,
the exposed conductive parts of the electrical installation being grounded.)
Controller Expansion Power Requirements
The power input to the ac outlet distribution box must be between 200 to 240V with
a total of 15 Amp. Maximum output per outlet is 6 Amp. A fuse of 7 Amp protect
this equipment.
