The ac supply voltage is set using voltage selectors fitted to the fuse holders, located in the power supply unit at the rear of the frame, as described opposite. Before commencing, it is essential to disconnect the power from the frame. WARNING: Maintenance of these units should only be carried out by trained service personnel.

A range of different modules may be accommodated by installing various motherboard sections. The three currently available types are designated ‘type 1’, ‘type 2’ and ‘type 3’. Configuration is usually set at Pro-Bel and does not normally need to be adjusted. However, frames initially supplied with some motherboard sections omitted can be upgraded in the field.

This section is treated as a complete unit comprising a regulator card (1185) and termination assembly. The regulator card provides dc supplies to the converters. It is always used with an ADC and DAC termination assembly (1653) fitted to the rear of the frame.

The type 3 motherboard permits five of these cards to be accommodated in the rackframe, alongside other conventional modules. Optical modules are supplied with blanking panels with cut-outs to be fitted to the rear of the frame. The fibre and coaxial connectors protrude through slots in the motherboard and must be secured to the rear panel using a lock washer and retaining nut from the rear of the frame.

The 6063 is fitted with an 1176 dual transformer unit which has an output monitor socket. The unit is electrically connected via flying leads with eyelets that are screwed to the motherboard. Power supplies are fitted from the rear of the frame and are secured by four screws.

There are 4 monitor output connections, two from each transformer. All are ac outputs. Typical output voltage will be 14V to 20Vac depending on loading in the frame. The pins from ac input 1 are labelled +1 and -1 and from ac input 2, +2 and -2. The module has indicator lamps for each ac input to show that an input voltage is present.

The incoming mains is stepped-down via transformers within the power supply unit to 14-0-14 volts. This is connected to the first motherboard section via flying leads from the transformers. It is linked between motherboard sections using power sockets and jumper links. When type 2 modules are used, the regulator card (1185) provides local regulation.
