2.3.2 Input Connections
(1) The input connector board is located on the right side of the rear panel.
(2) The power cable must be rated for at least 85°C.
(3) The power cable must be within 6AWG-8AWG. (Note: 10AWG-12AWG is required for
the 62020H-150S Model.)
(4) See Figure 2-3 (a), (b) to connect the cables to the 62000H. See Figure 2-5 to connect
the cables to the 62020H-150S. Then perform the following steps:
a. Remove the input terminal safety cover from the rear panel of the DC Power
Supply.
b. Scrape off any coating on the power cable tip (the bare portion is about 1cm) and
use an O type terminal to crimp it. (For the 62020H-150S, the bare portion needs to
be tinned.)
c. Secure the power cable to the input terminal with a Phillips screwdriver with a lock
torque in the 30-40 (kg-cm) range. (For the 62020H-150S, insert the power terminal
and use a Phillips screwdriver to secure it.)
d. Lock the safety cover to avoid electric shock.
e. Secure the safety cover latch and safety cover to prevent the cable from falling or
the electric terminal from being exposing.
