Transformer 100a, supplies filament and anode current for 3 transmitter and 3 receiver valves for the 100 Watt transmitter. This transmitter was fitted into the armoured reconnaissance vehicles and command armoured personnel carriers. Range of the transmitter in the switching position “Tg“ (Telegraphy) while stationary was 150 km and while in motion, with the frame or star antenna, approximately 80 km.

 The transformer switched itself on automatically by relays, when turning on transmitters with a switch to  position “Tn “(Telephony) or „Tg” (Telegraphy).

7     Power supply

 The power supply for radio equipment is supplied by the main batteries via power converters and transformers.

The accumulators are connected through the main switch NPA line 2X 10 mm² to the junction box Z 23. The junction box contains safety devices for the different electric circuits and is fitted on tie bar, behind the radio operator.

When stationary, the installed GG 400 protects the main drive accumulators. This machine is fitted in the rear right recess. The exhaust from the unit is provided by a pipe connected to the turret roof.
On the outside, this pipe can be locked  by a screw. The accessories belonging to the GG400 (spare parts etc.) are behind the set, in a special storage container.

Above the set, is a switchbox connected by NPA cable 2X10 mm², to the accumulators' main switch.

The switchbox contains a safety device that allows turning off the GG 400 from the electrical system. The transformers are firmly mounted to base plates. The radio operator 1has the transmission transformer U 30 and/or U 20, the base plate U 20 and for the receiver’s transformer EUa the base plate EUa. The base plate U 20 is in the recess to the right of radio operator1.
The base plate EUa is installed under the radio operator’s seat. The base plate U 20a connected by NPA cable 2 X 10mm² and the base plate EUa with NPA cable 2 X 1.5 mm² and the junction box Z 23. 8.    
                                                                                                   Rotary Converter and turret hook up

12 V power supply for the turret intercom, comes through a slipring transducer 8 tlg., Ausf.E, from the hull main accumulators.

The NPN cable 2X10mm² (Box Z23) and two cables from 6X0.5 mm² (intercom boxes), are connected to the slipring transducer’s stator.
Connected to the rotor part of slipring are 2 cables, one 9-core cable and one 2-core cable firmly attached. The 9-core rubber cable leads to Box Pz.Nr.5c, and the 2-core cable to an elbow plug.
When turret is removed for maintenance, junction box Pz NR.5C two cables are disconnected by means of a patch cord with a plug.
In addition, the box has 4 safety devices for the electrical mechanism. The junction box Pz Nr.5 C as well as the plug is attached at the turret’s rear wall.
 Transformers for receiver and transmitter EU.U10A are mounted on base plate, near radio operator 2. Base plates are located inside the turret, behind the supporting bracket, in place of the turret MG. The base plate U10A is connected by a NPA cable with 2 X 10-mm² cable with an elbow plug. The connection of the EUa base plate, is made with NPA 2 X 1.5 mm² cable at the base plate U 10 A.

GG 400 equipment is tightly fitted and stored in the turret’s rear right recess. Connection is made with rubber cables to the electrical system from the switchbox (pay attention to correct polarity). The exhaust pipe from the set is firmly attached to the vehicle (tightening nuts firmly, provides full fumes exhaust.) When using the GG 400, unscrew and removed the exhaust external cover cap for the outlet exhaust housing,
