Alpha Technologies XM2, XM2-HV, XM2-HP - Manual (Page 41)

3.0 Configuration
3.1 Power Distribution Board (PDB) Setup
The PDB must be configured to correctly match actual power supply features and
specifications. Adjustable parameters are shown in Table 3-1.
There are configuration setting features on the PDB that cannot be changed. These
configurations are included in the PDB setup instructions as an aid to troubleshooting and
as a reference to verify configuration. Only qualified technicians should configure the PDB.
Output Switches
Frequency (SW1-8): Factory set to match the ferroresonant transformer operating
frequency of either 60Hz or 50Hz. Changing this setting does not change the operating
frequency of the XM2. Do not change this setting.
Battery Voltage (SW1-7 and SW1-6): Factory set to match the ferroresonant transformer
and inverter module battery operating voltage of either 36Vdc or 48Vdc. Changing this
setting does not change the battery voltage of the XM2. Do not change this setting.
Power Rating (SW1-5 and SW1-4): Factory set to order. Change this setting as needed
during output voltage reconfiguration. The power rating must match both the model and
output voltage of the power supply.
Only qualified technicians should change the power
rating setting.
Output Voltage (SW1-3 and SW1-2): Factory set to order. Change this setting as needed
during output voltage reconfiguration. Output voltage must match both the model and
output voltage of the power supply.
Only qualified technicians should change the output
voltage setting.
Output Current (SW1-1): Factory set to order. May require changing as part of output
voltage reconfiguration. Output current must match both the model and output voltage of
the power supply.
Only qualified technicians should change the output current setting.
Input Switches
Input Voltage (SW2-6, SW2-5, SW2-4, JP1 and JP2): Factory set to order, but can be
changed as needed when configuring the input voltage (120Vac to 240Vac or 240Vac to
120Vac). All input voltage elements, three switches and two jumpers, must be set to match
input voltage configuration. Reconfiguration should only be performed by a qualified
technician.
Input Tolerance (SW2-7): Factory set to match the power supply transformer. Changing
this setting can result in damage to the transformer. This setting should never be changed
on standard models.
SW2-1, SW2-2, SW2-3, SW2-8 — Unused: These switches are unused and should never
be changed.
