Connecting to the DC Power Source

To connect the ANH-8/DC to the power source:

Ensure that the power switch is in the OFF (0) position

(Figure 2-19)

Using a flathead screwdriver, loosen, but do not remove, the screws on the
terminal blocks marked -VDC and RTN

(Figure 2-19)

Figure 2-19.

ANH-8/DC Power Switch and DC Terminals

Strip 3/8 in. (10 mm) of insulation from the end of a #16 or #18 AWG
cable.

Insert the stripped end of the cable into the -VDC terminal block, the
minus lead

(Figure 2-20)

Tighten the screw beneath the -VDC terminal block to establish the
electrical connection.

Danger:

Due to high-energy hazards, only qualified service personnel are

permitted to connect the ANH-8/DC to the power source. Ensure that the
connection is to an isolated -48 V or -60 V source (reinforced insulation from
the main [AC] power).

Note:

Although #18 AWG cable is adequate, we recommend #16 AWG cable

to ensure minimal voltage drop from the power source.
