Installation
a) The Ampere rating of the fuse is not less than NEC Ampacity of 125% of the Rated Continuous DC Input
Current (
Column 3
) - Refer to NEC-2014 (
National Electrical Code
) - Section 215.3
b) Standard Ampere Rating of Fuse equal to the above NEC Ampacity of 125% of the Rated DC Input
Current has been used - Refer to NEC-2014 (
National Electrical Code
) - Section 240.6(A)
c) Where Standard Fuse Rating does not match the required Ampacity of 125% of the Rated Continuous DC
Input Current (
Column 3
), the next higher Standard Rating of the fuse has been used - Refer to NEC-2014
(
National Electrical Code
) - Section 240.4(B)
d) Type of fuse: Fast-acting, Current Limiting, UL Class T (
UL Standard 248-15
) or equivalent
3.5.7 Using Proper DC Cable Termination
The battery end and the inverter end of the wires should have proper terminal lugs that will ensure a firm and tight
connection. Choose lugs to fit the wire size and the stud sizes on the inverter and battery ends.
Tightening torques to be applied to the wiring terminals are given in Table 3.1.1:
TABLE 3.1.1 TIGHTENING TORQUES
Battery Input Connectors
External Charger Input Connectors
AC Input and Output Connectors
70 kgf.cm
(5.0 lbf.ft)
35 kgf.cm
(2.5 lbf.ft)
7 to 12 kgf.cm
(0.5 to 0.9 lbf.ft)
3.5.8 Reducing RF Interference
To reduce the effect of radiated interference, shield the wires with sheathing / copper foil / braiding. For details, refer
to Limiting Electro-Magnetic Interference" at Section 1.3.4.
3.5.9 Taping Battery Wires Together To Reduce Inductance
Do not keep the battery wires far apart. Keep them taped together to reduce their inductance. Reduced inductance of
the battery wires helps to reduce induced voltages. This reduces ripple in the battery wires and improves performance and
efficiency. For details, refer to Limiting Electro-Magnetic Interference" at Section 1.3.4.
3.6 AC INPUT AND OUTPUT - LAYOUT AND CONNECTION ARRANGEMENT
!
CAUTION!
1. The installation instructions shall indicate that the wiring methods in accordance with the National Electri-
cal Code, ANSI/NFPA 70 are to be used.
2. Before making any AC connections, make sure that the unit is disconnected from the battery bank and
that no AC power is connected to the unit.
3. The AC output of the unit should never be connected to an AC power source. This could cause severe
damage to the unit and this damage will not be covered under warranty.
!
ATTENTION!
1. Les instructions d'installation doivent indiquer que les méthodes de câblage conformes au National
Electrical Code, ANSI / NFPA 70 doivent être utilisées.
