Table 4-1 also provides each power supply’s holdup time specification, which is
the time the supply will continue to operate within specification after its input
power is interrupted. This information may be useful in specifying Uninterruptible
Power Supply (UPS) systems.

All fuses listed above are “slow blow”.
Significant inrush currents are possible when current is applied to the main
power supply. The magnitude of the inrush current depends on the power source
impedance, so Woodward cannot specify the maximum inrush current. Time-
delay fuses or circuit breakers must be used to avoid nuisance trips.
The 5009 control includes a set of two main power supplies. Input power ratings
are identified in Table 4-1 and on each power supply’s front panel. Refer to
Chapter 6 of this Volume for all power supply specifications.
When a cabinet is supplied with the system, input power connections and PE
ground are made through panel mounted Phoenix type terminal blocks. These
terminal blocks accept wires from 0.08–2.5 mm² (20–8 AWG). For a good
connection the inserted wires should have the insulation stripped back by about
6 mm (1/4”). Refer to Figure 4-20 for a wiring diagram of the cabinet’s input
power terminals.
When a cabinet is not supplied with the system, input power connections and PE
ground are made through terminals on the front of each main power supply.
These terminals accept wires from 0.08–2.5 mm² (20–8 AWG) wire. For a good
connection the inserted wires should have the insulation stripped back by about
8 mm (1/3”). Figure 4-20 displays a 120 Vac/150 Vdc or a 220 Vac power
supply’s input terminals. The 24 Vdc power supply model uses larger copper
input terminals to accommodate the required 10 mm² (8 AWG) wire. A
green/yellow wire must be used for PE ground connection. Fixed wiring
installation is required for power supplies.
