For HSC3020C installations, complete the following steps:
1. If mounting the power supply inside the cabinet, attach it as per figure 2-9 using supplied hardware. Use cable ties to
secure the DC wires to the enclosure.
IMPORTANT!
Minimum 1/4-inch (6.4 mm) separation must be maintained at all points between battery/AC wiring and all other wiring con-
nections. Do NOT route any wiring over circuit boards. Maintain at least 1 inch (25.4 mm) separation.
2. Install the grommet strip (available separately – p/n 57000933) into the opening on back of cabinet as indicated in figure
2-4. Route the AC cable out of the enclosure through the opening indicated in the diagram.
3. If mounting the power supply outside the enclosure, attach it to the wall using suitable hardware. Route DC wires into the
enclosure and secure them with cable ties. See figure 2-9 for approved wire length/gauge.
