Page 6: Installation
Caution: The 231HC Amplifier’s mass is approximately 47 kg (100 lbs). In many cases, the Amplifier will be pre-installed by GMW into a 19” EIA equipment rack. If it is not, care should be taken during rack mounting to avoid personal injury or damage to the equipment. -
Page 7: Electrical Connections
3.3 - Electrical Connections Even if the Amplifier was ordered as a complete system and assembled into a rack by GMW, it is still recommended to follow and verify the following section as connections may have loosened during shipment. Refer to drawing 13907-0003-0, Rev. C for a detailed connection diagram. -
Page 8: System Description
The DC Supply provides the 160V, 31A (or 160V, 63A) dc power to the 231HC Amplifier and is buffered by the 231HC’s internal 200mF capacitor bank. The capacitor bank provides current for short duration overloads of the DC Supply. -

Page 11: Initial Operation
Once the 231HC system is connected it is time to perform initial system operational checks. Start by switching on the auxiliary power supply in the 231HC. The switch is in the power entry module at the rear of the unit. -

231HC Bipolar Amplifier. If GMW’s Magnet Control software is not used, it is still possible to computer control the 231HC Bipolar Amplifier by writing custom software to communicate with the USB-6251. The table below describes the channels used and their functions. -
Page 13: Maintenance
Section 5 MAINTENANCE The 231HC Bipolar Amplifier should operate for many years without any trouble provided that the following basic maintenance points are observed. Always remember that the ac power should be disconnected before performing any maintenance procedure. The 231HC generates lethal voltages and must not be operated with damaged components, protective covers or cable insulation. -
