Dc Wiring; Removing Dc Protective Cover; Dc Terminal Labels - Delta 100kW PCS Installation Manual

DC Wiring

1. Prepare DC cables: Prepare several 1/0 size, 1000V cables for DC wiring. The PCS supports
up to 3 sets of battery connection, and each set of battery connection requires two cables (one
for positive, the other for negative). Connect the DC cables to the two-hole lugs which are
available in the accessory kit, and use heat shrinkable tubing on the junction between the cables
and lugs to prevent the exposure of the conductive part.
2. Remove protective cover of DC terminals: Remove the protective cover in front of the DC
terminals as shown in the following figure. There are two labels indicating the polarity of the
terminals: "DC+" for positive, and "DC-" for negative. Each pole provides 3 two-hole terminals
and can be connected side by side.
