Route Power through Intermediate Power Supply Box
You may route the main power supply through a VG4-PSU1 (120 V transformer) or through a
VG4-PSU2 (230 V transformer) Power Supply Box before connecting the power to a VG4-PA0
(24 V, no transformer) Power Supply Box. The main issue with this configuration is that the 5-
pin power out connector from the VG4-PSU1 or VG4-PSU2 does not match to the 3-pin power
input of the VG4-PA0 power supply. The illustration below depicts:
– A VG4-PSU1/VG4-PSU2 Power Supply Box.
– The main power supply connected to the P101 connector and to the grounding screw.
– The 24 VAC power out wire connected to the P107 heater power connectors.
