2. SELECTION INSTALLATION
2.1 Location
Proper location of the WATT-Inverter is imperative to achieve specified performance & normal operation
lifetime. The Inverter should always be installed in areas where the following conditions exist.
*
Ambient operating temperature:
Enclosed type: -10
°
to 40
°
C (14
°
to 104
°
F)
*
IP rating : IP 20 for all models.
*
Protected from rain & moisture.
*
Shielded from direct sunshine.
*
Free from metallic particles and corrosive gas.
*
Free from excessive vibration. (below 0.5G)
2.2 Positioning

2.3 Changing PC boards
1. Set Fn_95 to 1111
2. Set Fn_00 to match the specified model (Refer to Fn_00)
3. Set Fn-95 to 1111
4. Detect the P-N DC voltage and input the value into Fn_96. ( P is on TM1, N
is the test pin on main board)
