Primary Power Source (AC) and Earth Ground Connections
AC power connections are made inside the control panel cabinet. The primary power
source for the panel is 120 VAC, 50/60 Hz, 2.3 amps for the MS-2/MS-4 or 240 VAC,
50 HZ, 1.15 amps for the MS-2E/MS-4E. Run a pair of wires (with ground conductor)
from the protected premises main breaker box to TB8 of the main circuit board. As per
the National Electrical Code, use 14 AWG (2.00 mm
