10. Torque all AC wiring connections to 20 inch-pounds. Torque all DC cable connections 10-12 foot-
pounds. Be extra cautious to reduce the risk of dropping a metal tool onto batteries. It could short- circuit
the batteries or other electrical parts resulting in sparks that could cause an explosion.
11. Tools required to make AC wiring connections: Wire strippers, ½" (13MM) open-end wrench or socket,
Phillips screw driver #2, 3/16” ( 5mm) & 1/4" (6MM) slotted-screw driver, and a torque wrench.
12. The Power Module is intended to be used with a battery supply with a nominal voltage equal to the last
two digits in the inverter/charger’s model number. For example: a SW4024 is a 24 volt inverter, a DR1512 is
a 12 volt inverter. (The first two digits are Power output in hundreds of watts)
13. Instructions for mounting: See mounting instruction section of this manual. For battery
installation and maintenance: read the battery manufacturer’s installation and maintenance
instructions prior to operating.
14. DC GROUNDING INSTRUCTIONS - This Power Module should be connected to a grounded,
permanent wiring system. For most installations, the negative battery conductor should be bonded to the
grounding system at one (and only one point) in the system. All installations should comply with all national
and local codes and ordinances.
15. Fully assemble each module from the bottom up before adding the next module, up to a maximum stack
height of four modules. This includes attaching and tightening all mounting hardware. The strength and
stability of the modular system is dependent on all fasteners being connected and tightened properly.
Personal Precautions
1. Someone should be within range of your voice to come to your aid when you work near batteries.
2. Have plenty of fresh water and soap nearby in case battery acid contacts skin, clothing, or eyes.
3. Wear complete eye protection and clothing protection. Avoid touching eyes while working near batteries.
Wash your hands when done.
4. If battery acid contacts skin or clothing, wash immediately with soap and water. If acid
enters eye, immediately flood eye with running cool water for at least 15 minutes and get
medical attention immediately.
5. Baking soda neutralizes lead acid battery electrolyte. Keep a supply on hand in the area of the batteries.
6. NEVER smoke or allow a spark or flame in vicinity of a battery or generator.
7. Be extra cautious to reduce the risk of dropping a metal tool onto batteries. It could short-circuit the
batteries or other electrical parts which may result in a spark which could cause an explosion.
8. Remove personal metal items such as rings, bracelets, necklaces, and watches when working with a
battery. A battery can produce a short-circuit current high enough to weld a ring or the like to metal, causing
severe burns.
9. This is a negative grounded system. Always connect the positive or hot wires before connecting the
negative or neutral wires when installing all equipment. This will reduce the chance of shorting the wires to
the cabinet or equipment when routing wires. This is particularly important when routing the battery cables.
10. As an additional precaution, the ends of the battery cables should be taped when routing
through cabinet openings and conduit.
