28 Controller Installation
7.6.4 Input Wiring for Solar-direct Systems
WARNING – Beware of high voltage!
Electric shock hazard! Hazardous
electricity may be present and can shock,
burn, or cause death! Authorised, qualified
personnel only!
The PV generator can produce hazardous voltage even un-
der low light exposure. To prevent shock hazard while wiring
the array, leave one or more wires disconnected or cover the
solar array with opaque material.
Table 5: Max. voltage input
Controller
Max. DC input voltage
PS2-150 50 VDC
PS2-200 100 VDC
PS2-600 150 VDC
PS2-1800 200 VDC
PS2-4000 375 VDC
CAUTION – An input voltage higher than
specified in “Table 5: Max. voltage input”
on page 28 will damage the controller
and void the warranty. Damage may occur
if the solar generator array is wired
incorrectly. Measure the voltage and
confirm the polarity before connecting the
power to the controller.
Connect the positive terminal of the PV modules to + and
the negative terminal of the PV modules to –. Connect the
protective ground wire to an appropriate ground system.
Refer to “7.6.1 Terminal Descriptions” on page 22 for
terminal descriptions and to “7.6.6 Grounding” on page
30 for grounding instructions.
