1.4.3 X302 Power supply 2 terminal block
Terminal block X302 may only be used for an additional PS300 when the system
requirements exceed 300 W. The housing (3HU) is the only housing that is capable of
having two PS300 supplies connected at the same time. No power supply (170 W)
may be connected to terminal block X302.
Terminal X301 must always have a power supply
connected. When a single power
supply is used, it must be connected to terminal X301.
Check whether jumper X305 is in position 2-3 before PS300 #1 is connected to X301
or #2 to X302. Make sure line voltage is not present on the system, and that the
breaker in the panel is off. Both power supplies need to be connected before line
voltage is switched on at the panel. X301 and X302 should never be
connected/disconnect with line voltage present. Batteries may only be connected after
the system is brought up on line voltage power.
