terminals. High voltage wiring is always made to the upper Hi terminal block and low voltage (24/48
V) wiring is always made to the lower Lo terminal block.
• Use only #16 gage wiring when connecting terminal blocks.
• The maximum wire length between the terminal block and power source must not exceed 6 m (20 ft)
for 24 V power supplies or 18 m (60 ft) for 48 V power supplies.
