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.
