You can conveniently power the SG 2000 by applying 60 Vac or 90 Vac to housing port 2. This port
is not used for RF purposes. All ports are rated at 15 amperes maximum and are fused with common,
blade-type 20-ampere automotive fuses. The 10-ampere fuse protects the dc power supply wiring
and can also be used to disconnect ac power from the power supply.
In addition to providing overcurrent protection, fuse locations also determine the paths for ac
bypassing through the housing.
Figure 3-3 diagrams fuse configurations for ac and dc powering:
