Appendix A – Internal Links and Fuses
Fuses (Mains Inlet)
The mains inlet contains a single 1 amp 1.25" time delay fuse (SSL Part No. 35FJJ310). To change it disconnect the mains inlet, then using a small screwdriver prise open the mains selector cover (see illustration on page 6.). Under this cover is a removable carrier that contains the fuse – pull the carrier out to access the fuse inside. Test and replace the fuse with the same type and value if necessary.
Internal Fuses
The internal power rails are also individually fused. These fuses should only be changed by suitably experienced staff. They are listed below:
Fuses (629610X2 Power Regulator Card)
+48V FS1 - 500mA wire ended (SSL part No. 35F5E250)
Fuses (629612X1 Main Card)
+15V FS3 - 3 amp wire ended (SSL part No. 35F5E330)
+18V FS4 - 3 amp wire ended (SSL part No. 35F5E330)
+5V FS5 - 3 amp wire ended (SSL part No. 35F5E330)
Links
LK1 | Compressor ‘Auto Attack’. Normally not fitted. |
| Fitting across pins 1 & 2 makes the compressor attack time program dependent when ‘Linear |
| Release’ is selected. |
| Fitting across pins 2 & 3 makes the compressor attack time program dependent normal |
| (logarithmic) release is selected. |
LK2 | Additional HF |
| across pins 2 & 3 to enable. |
LK3 | Solder link. Links digital and analogue 0V. Do not remove. |
LK4 | Links chassis and analogue 0V. Normally fitted. Remove to increase impedance to 10Ω. |
