The following points must be observed for the DC Wiring.
• The DC positive and negative cables connected to the GP-SW1500TS from the
battery bank should be linked together with zip ties or electrical tape every 6”.
This helps to reduce radio frequency interference and reduces the effects of
inductance both of which improve the Inverter waveform and reduces the wear
of the Inverters lter capacitors.
• To ensure optimum Inverter performance the number of connections between
the battery bank and the GP-SW1500TS unit should be minimized except from
the over-current and battery disconnect devices. All additional connection points
will cause extra voltage drops.
• The Battery bank voltage must match the DC voltage required by the GP-
SW1500TS, which is 12V.
• All DC cable wire terminations should use a crimped and sealed copper ring
terminal lugs.
• Make sure all cables have a smooth bend radius and no kinks are present.
• Colour code all DC Cables coming to / from the battery bank. Use coloured
electrical tape or heat shrink tubing. Red for positive (+), Black for negative (-)
and Green for DC ground.
