Ascend Single Phase Charger Operation Manual
3.4.1. AC Input Connections
Verify the branch circuit breaker or fused disconnect is locked out.
Confirm that the Serial tag voltage rating is correct for the AC input supply voltage.
Connect the Charger to the appropriate source of AC power via conduit knockout openings on the
charger enclosure.
The earthed conductor of the AC input circuit must be connected to the charger-grounding stud left of
the terminals. When routing the cable, make sure that the wire is not laying over any sharp edges which
may cut into the wiring. AC Input wiring must be kept at least 1/4" (6.3 mm) away from all output,
alarm, data interface wiring, and from other uninsulated electrical parts not connected to the input
conductor.
20A and 40A models utilize compression terminals and will accept 16-8 GA (1.25-8mm
2
) wire, reference
Figure 3.
