3 Product description 3.2.2 Setup/models The COMTAP® ARS is produced in a single-phase and three-phase design with a maximum possible rated through-current of 2400 A. The design of the COMTAP® ARS and the designation of its main parts are shown in the installation drawings in the appendix (see page [►...
3 Product description 3.2.3 Name plate The name plate is on the head of the COMTAP® ARS. Figure 2: Position of name plate 3.2.4 Protective devices Tap-change supervisory control The COMTAP® ARS is equipped with a tap-change supervisory control, which is fitted in a housing on the head of the COMTAP® ARS (see page [►...
3 Product description The bevel gear changes the direction from vertical to horizontal (see drawing 892916). Accordingly, the vertical drive shaft has to be mounted between drive and bevel gear and the horizontal drive shaft between bevel gear and on-load tap-changer or de-energized tap-changer.

Commissioning transformer at operating site Checking motor-drive unit Before commissioning the transformer, repeat the function tests on the mo- tor-drive unit as described in MR operating instructions for motor-drive unit. Danger of death or severe injury! WARNING Danger of death or severe injury due to incorrect operation! ►...
4 Commissioning transformer at operating site Performing trial tap-change operations Before energizing the transformer, test change operations must be carried out to check the mechanical function of the COMTAP® ARS. DANGER! Switch off transformer on high and low-voltage side. Fail- ure to do so may result in severe injuries and property damage.
5 Operation Operation The following sections describe how to operate the COMTAP® ARS and monitor the COMTAP® ARS and motor-drive unit. Temperature range When using a vegetable oil as insulating fluid, the permissible temperature range for operation of the DEETAP® DU/COMTAP® ARS is limited. Please observe the relevant information in the specific order documents and on the indicator plate on the drive.
5 Operation Actuating motor-drive unit with hand crank Danger of explosion! WARNING Unauthorized operation of the motor-drive unit with the hand crank may re- sult in death or serious injury. ► Never operate the motor-drive unit electrically or with the hand crank before the transformer has been disconnected if you think there may be a fault in the transformer or on-load tap-changer / de-energized tap- changer.
5 Operation Insert the hand crank mounted in the motor-drive unit into the hand crank aperture in the upper cover plate. ð The built-in hand crank interlock switch interrupts the motor circuit at two poles. The control circuit will not be interrupted. NOTICE! Turn in one direction with the hand crank until the pointer has fully circled the tap-change indicator once and is again in the mid-posi-...
6 Maintenance Maintenance Safety precautions Danger of death and severe injury! WARNING An energized transformer and energized COMTAP® ARS components could cause death or serious injuries during maintenance work! ► Adherence to the following safety precautions is mandatory. Switch off transformer on high and low-voltage side. Lock transformer to prevent unintentional restart.
