Inverter Applications - Vector MAXX SST 3000 VEC051 Owner's Manual

Not all fluorescent lamps operate properly with this type of inverter. If the bulb
appears to be too bright, or fails to light, do not use the lamp with this inverter.
Some fans with synchronous motors may slightly increase in speed (RPM) when
powered by the inverter. This is not harmful to the fan or to the inverter.
Certain rechargers for small nickel-cadmium batteries can be damaged if plugged
into the inverter. In particular, two types of appliances are susceptible to damage:
• Small, battery-operated appliances such as flashlights, cordless razors and tooth
brushes that can be plugged directly into an AC receptacle to recharge
• Certain battery chargers for battery packs that are used in some cordless
hand-tools. Chargers for these tools have a warning label stating that
dangerous voltages are present at the battery terminals
DO NOT use the inverter with the above two types of equipment.
The majority of portable appliances do not have this problem. Most portable
appliances use separate transformers or chargers that plug into AC receptacles to
supply a low-voltage DC or AC output to the appliance. If the appliance label
states that the charger or adapter produces a low-voltage DC or AC output (30
volts or less), there should be no problem powering that charger or adapter.

2.0 INVERTER APPLICATIONS

Aside from issues of supplying power to higher wattage appliances, the inverter
must be supplied with a constant source of high current DC from a bank of batteries.
At full 3000 watt load, the DC input requirements are up to 300 amperes at
12 volts DC. The inverter has connections for direct wiring to AC power distribu-
tion circuits, and certain warnings must be observed during installation. Miswiring
can be dangerous.

NOTE: These installation procedures are for locally purchased wire fuse and fuse
holders. If a VEC085 cable set is purchased use the instructions provided
with the set.
1. Using tools and hardware, mount the inverter to the flat surface that you
have selected.
2. Mount the fuse holder to its mounting surface using appropriate hardware.
Ensure that the mounting hardware does not touch any of the fuse holder
contacts or fuse contacts. Ensure that the fuse is removed from its holder.
3. Measure the cable twice before marking the cable for cutting.
4. Cut one cable length to fit between the negative (-) connection power source
and the inverter's negative terminal, leaving a little slack in the cable.
5. Cut the remaining length of cable to be able to connect from the positive (+)
power source terminal to one side of the fuse holder, leaving a little slack.
6. Cut the remaining length of cable to connect the other side of the fuse holder to
the positive (+) terminal on the back panel of the inverter
7. Strip the insulation to 1-inch (2.45 cm) from the ends of each of the three cables.
NOTE: Some very flexible versions of 00 cables may not fit into the ring
terminals as they are slightly larger in diameter than the terminal's
opening. If necessary, you can remove up to 10% of the wire strands.
8. Sweat-solder the remaining copper strands at the inverter ends of the appropriate
cables onto the ring terminals to ensure a good connection. For safety reasons,
do this in an open space because it may require the use of a propane torch.
9. Crimp or clamp on a heavy-duty, battery-connection terminal to the other end of the
negative (–) and positive (+) cable. Connect the negative (–) cable battery terminal
to the negative (–) battery terminal connector.
10. Ensure that the inverter power switch is in the OFF position (See FIGURE 1).
11. Attach the ring terminal of the negative (–) cable onto the black stud terminal
(–) on the inverter back panel and tighten the retaining nut.
12. Connect the battery connector to the negative (–) battery terminal.
13. Attach the the positive (+) cable into the red stud terminal (+) on the inverter's
back panel (See FIGURE 2) and tighten the retaining nut.
14. Connect the other end of the (+) positive cable to one terminal of the heavy-duty
fuse holder.
15. Connect the other conductor of the heavy-duty fuse holder to the positive (+)
battery terminal.
16. Replce the stud terminal covers and secure with supplied screws.
