Quick Install Guide
1
AC Input (J9)
The primary AC input for the FPA Series power supplies. Multi-trans-
former supplies should have all transformer primaries connected to-
gether then connect to the AC Line. Input must be 120VAC 60Hz.

Always connect Earth Ground first and remove last
2
A8(P) Board
Zone Outputs
The zone outputs on the A8 boards distribute the transformer power
to the devices to be powered. These terminal strips are removable
and accept wire sizes from AWG14 - AWG22. Phasing is indicated on
the PC Board.
3
Output Selection Jumpers (JP1 - JP8)
These jumpers select which voltage buss input is selected for the out-
put. Jumper numbers correspond with the zone number (eg. JP1 is
the jumper for OUT1). Possible settings are as follows:
• Position 2 (Left) - 28VAC (18V for 16.5/18V FPA models)
• Position 1 (Right) - 24VAC (16.5V for 16.5/18V FPA models)
• Removed - Disable Output
4
Output Fuses (F1 - F8) - Optional
When using the fused version of the A8, these are the fuses for each
zone output. Fuse numbers correspond with the zone number (eg. F1
is the fuse for OUT1). When using the PTC version of the A8, the fuse
will be replaced with a soldered-in PTC.
5
Output LEDs (D1 - A8) - Green
These LEDs indicate the availability of voltage on a zone’s output.
When voltage is available on the output terminals, the LED is lit. LED
numbers correspond with the zone number (eg. D1 is the LED for
OUT1).
