3.5 Connecting the ROC800 to Wiring

The following paragraphs describe how to connect the ROC800 to

power. Use the recommendations and procedures described in the

following paragraphs to avoid damage to equipment.

Use 12 to 22 American Wire Gauge (AWG) wire for all power wiring.

Caution

Always turn off the power to the ROC800 before you attempt any type

of wiring. Wiring of powered equipment could result in personal injury

or property damage.

To avoid circuit damage when working with the unit, use appropriate

electrostatic discharge precautions, such as wearing a grounded wrist

strap.

To connect the wire to the removable block compression terminals:

1.

Bare the end (¼ inch maximum) of the wire.

2.

Insert the bared end into the clamp beneath the termination screw.

3.

Tighten the screw.

The ROC800 should have a minimum of bare wire exposed to prevent

short circuits. Allow some slack when making connections to prevent

strain.

3.5.1 Wiring the DC Power Input Module

Use 12 to 22 American Wire Gauge (AWG) wire for all power wiring.

It is important to use good wiring practice when sizing, routing, and

connecting power wiring. All wiring must conform to state, local, and

NEC codes. Verify that the hook-up polarity is correct.

To make DC power supply connections:

1.

Install a surge protection device at the service disconnect.

2.

Remove all other power sources from the ROC800.

3.

Install a fuse at the input power source (see

Figure 3-5

).

4.

Remove the terminal block connector from the socket.

5.

Insert each bared wire end into the appropriate power module

connectors:

For PM-12

(12 Volts dc source): into the clamp beneath the

appropriate BAT+ and BAT– termination screws.
