Notes:
The bypass system consists of the bypass switch (BPS) and bypass transformer if required (BPT).
References to Figures indicate applicable connection diagram.
N/A indicates the configuration is not available for this model of UPS.
MBB = Make Before Break Switch (Provides uninterrupted transfer).
BBM = Break Before Make Switch (Output will be interrupted for at least 30 milliseconds).
Explanation of Bypass Switch ordering code:
BPS xyzz
x = 1 : 40 Amp contact rating
x = 2 : 80 Amp contact rating
x = 3 : 125 Amps contact rating
y = M : Make-Before-Break contacts
y = B : Break-Before-Make contacts
zz = 3P : 3 pole switch
