the device
Make sure the supplied cover is always installed over high voltage screw-type
terminal blocks.
Electrical hazard – risk of damage to equipment
Do not connect AC power cables to a DC power supply terminal block. Damage to
the power supply may occur.

The screw-type terminal block is installed using Phillips screws and compression
plates, allowing either bare wire connections or crimped terminal lugs. Use #6 size
ring lugs for secure, reliable screws, which must be removed to make connections.

PS1 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 minimum #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.
A circuit breaker rated no higher than 20 A must be installed between the device
and the supply mains.
Whenever possible, use a separate circuit breaker for each power supply.
