Page 6: Section 2 Principles Of Operation
The MVC 236 is designed to operate from 60, 120, or 240 Vac nominal sources by making a simple tap change. Taps are also provided to select 32, 63, or 125 Vdc outputs. A jumper is used to select the proper input power frequency. -
Page 7: Section 3 Installation Instructions
INSTALLATION INSTRUCTIONS 3-1. MOUNTING a. Manual Voltage Control Module Mounting. The MVC 236 must be mounted vertically for maximum cooling. The unit can be mounted anywhere that the ambient temperature does not exceed the environmental conditions (refer to Table 1-2). -
Page 8: Spike Suppression Module Mounting
Figure 3-2. Manual Voltage Adjust Rheostat. b. Spike Suppression Module Mounting. The Spike Suppression Module will operate when mounted in any position. The Spike Suppression Module can be mounted in any location where the ambient temperature does not exceed the operational limits. Due to its rugged construction, the Spike Suppression Module can be mounted directly on the generator. -
Page 9: Interconnection
Incorrect use of such equipment could damage com- ponents contained in the device. a. General. The MVC 236 connects with the generator system as shown in Figures 3-4 and 3-5. Number 14 gauge wire or larger should be used for connections to the unit. -
