5.3.3 Power Supply Module

JMP1/JMP2: NO/NC Selects the contact position when the relay coil is de-energized. This relay coil is
fail-safe and energized when the power supply is functional. Therefore set the contact to NO if you
want the contact to open for alarm or NC if you want the contact to close for alarm.
JMP3: PWR ON/PWR OFF allows for de-energizing the module when inserted into the chassis with DC
power applied. Normally set to PWR ON.
5.3.4 Aux. Power Supply Module (for driving EM protective relays)
JMP1/JMP2: 46V (20mA) / 20V or 8V (200mA) - allows you to select either a 20mA or 200mA capable
source for use with carrier auxiliary relays such as KA-4 (ABB relay).
JMP3: 46V/20V - if JMP1/2 is in the (46V/20V) position, this allows selection between the 46V or 20V
option. The 46V option is used for 20mA carrier auxiliary relays such as KA-4 (ABB relay). The 20V
option is used for solid state relay systems such as ABB's STU or SKAU relay systems.
Note: This jumper setting doesn't matter when JMP1/JMP2 is set for 8V/200mA.

5.3.5 Power Amplifier Module

JMP1/JMP2: (Frequency Select ON/OFF) - Always set for ON in a UPLC-II™. This enables the frequen-
cy selectivity capability for the built-in TX reflected power meter, so that this meter reads correctly for
its own TX frequency. It is unaffected by other transmit signals coming into it.
For older UPLC units without the supporting hardware, this jumper allows the Power Amp to be used
in them without a problem by setting to OFF.
