2.2.1.1 Unit AC Input Power terminal block (J2)
The Unit AC power terminal block is used to provide AC power to the Tank Gate Interface. The
power requirements for the Tank Gate Interface are 100-240 VAC, 50/60 Hz. The AC Input
Power terminal block is shown in the figure below.
Figure 2-4: AC Input Terminal Block
2.2.1.2 Surge Protection (Surge Gnd) terminal block (J4)
The Surge Gnd terminal block is used to connect the surge protection components (gas tubes,
MOVs) to earth ground. Ensure there is a low impedance path (< 1ohm) to earth ground (a
ground rod or grounding system).
