SW Series Inverter/Charger
Part No. 2031-5
Rev. B: Sept 1, 1999
4. Use of battery cable or custom attachment not recommended or sold by Trace Engineering for the
SW Series Inverter/Charger may result in a risk of fire, electric shock, or injury to persons.
5. Do not disassemble the inverter/charger. Take it to a qualified service center when service or repair is
required. Incorrect re-assembly may result in a risk of electric shock or fire.
6. To reduce risk of electric shock, disconnect all wiring before attempting any maintenance or cleaning.
Turning off the inverter will not reduce this risk. Solar modules produce power when exposed to light.
Cover them with opaque material before servicing any connected equipment.
7. WARNING – RISK OF EXPLOSIVE GASSES
(a) WORKING IN VICINITY OF A LEAD ACID BATTERY IS DANGEROUS. BATTERIES
GENERATE EXPLOSIVE GASES DURING NORMAL BATTERY OPERATION. FOR THIS
REASON, IT IS OF UTMOST IMPORTANCE THAT EACH TIME BEFORE SERVICING
EQUIPMENT IN THE VICINITY OF THE BATTERY, YOU READ THIS MANUAL AND FOLLOW
THE INSTRUCTIONS EXACTLY.
(b) To reduce risk of battery explosion, follow the instructions in this manual and those published by
the battery manufacturer as well as manufacturer of any additional equipment used in the vicinity
of the battery. Review all cautionary markings on these products.
SPECIAL NOTICES
1. Tools required to make AC and DC wiring connections: Wire strippers; 1/2" (13MM) open-end or
socket wrench; Phillips #2 screwdriver; flat blade 1/4" (6MM) screwdriver.
2. No terminals or lugs are required for hook-up of the AC wiring. AC wiring must be copper wire and
rated for 75
°
C or higher. The maximum wire size for the AC terminals is #6 AWG (4.11 mm diameter).
Battery cables must be rated for 75
°
C or higher. Crimped and sealed copper ring terminal lugs with a
5/16 hole should be used to connect the battery cables to the DC terminals of the inverter/charger.
Soldered cable lugs are also acceptable.
3. Torque all AC wiring connections to 20 inch-pounds. Torque all DC cable connections to 10-15 foot-
pounds. Avoid dropping metal tools onto the batteries. A short-circuit could result in a spark, fire or
possible explosion.
4. This inverter/charger is designed for use with a battery supply with a nominal voltage that matches the
last two digits of the model number (e.g., 12 Volt with an SW2512).
5. For instructions on mounting, see the MOUNTING section on page 17 of this manual.
6. NOTE: Do not use the keyhole mounting slots for permanent installations. For battery installation and
maintenance refer to the battery manufacturer’s instructions.
7. No AC or DC disconnects are provided as an integral part of this inverter. Both AC and DC
disconnects must be provided as part of the system installation. Refer to the INSTALLATION section
beginning on page 15 for more information.
8. No overcurrent protection for the battery supply is provided as an integral part of this inverter.
Overcurrent protection of the battery cables must be provided as part of the system installation. Refer
to the INSTALLATION section beginning on page 15 and the DC DISCONNECT AND
OVERCURRENT PROTECTION section on page 23 for more information.
9. No over current protection for the AC output wiring is provided as an integral part of this inverter.
Overcurrent protection of the AC output wiring must be provided as part of the system installation. Refer to
the INSTALLATION section on page 15 and the AC WIRING section on page 18 for more information.
10. The AC output neutral conductor and DC negative conductors are not connected (bonded) to the
inverter chassis. Both the input and output conductors are isolated from the enclosure and each other.
System grounding, if required by sections 690-40, and 690-42 of the National Electric Code,
ANSI/NFPA 70-1996, is the responsibility of the system installer. All installations must comply with
local and national electrical codes and standards.
