Be sure that selected gate location has required clearance for arm movement (and counterweights on model BG790). Refer to the dimensional drawings on page 3. 2. Run electrical power to the site according to local electrical codes (Figure 1). See chart on page 7 for correct wire size and length of run. If the wire gauge is too high (wire too small) or the run is too long, the gate may not run properly or may not run at all. Damage to components may result. IMPORTANT NOTE: Be sure that the available power is the proper voltage, phase, frequency, and amperage to supply the gate. Refer to gate nameplate located inside the service cover. 3. Select locations for control equipment and run any control wiring that may be needed (such as loop wires, card readers, ticket spitters, pushbuttons, etc.).
