Safety
Refer to Figure 0-21 on page lvii for voltage label and power rating plate location, and to page
YZ060, sheet 1 for the PS2 box voltage adjustment by SW1.
Check that:
The power rating plate and the voltage label of the 3745 are consistent with the frequency and
the voltage measured at the customer's power supply. If they are inconsistent, inform your
branch office.
3746-900 Input Power voltage
The power rating plate indicates the voltage range available (200/220/240) and the frequency
(50/60&rlb.Hz).
The 3746-900 voltage range is 200/220/240.
Check that:
The power rating plate of the 3746-900 is consistent with the frequency and the voltage meas-
ured at the customer's power supply. If they are inconsistent inform your branch office. Refer to
“3745/3746-900 Safety Label Identifications” on page lx for the power rating plate location.
dc Input Voltage
For dc input, the customer's voltage must be within -40.0 V to -60.0 V. There is no adjustment
for the optional dc input.
ac Input Voltage
For ac input, the customer's voltage must be within 180 V to 260 V.
Adjustment of the input voltage can be done according to the customer voltage on TB1 of the
transformers located at the rear of the 3746-900.
Important Note
:
Since the 3745 can be remotely powered ON, all the following procedures must be performed with the
power control function on the 3745 and the 3746-900 control panel set to local mode.
Controller Expansion Input Power Voltage
The power rating plate indicates the voltage range available (200/240) and the frequency (50/60 Hz).
Check that the power rating plate of the controller expansion is consistent with the frequency and the
voltage measured at the customer's power supply. If they are inconsistent inform your branch office.
Refer to “Controller Expansion Label Location” on page lxii for power rating plate location.
