Figure 15: RSG2000 Series Philips Screw Terminal Block

The RSG2000 Family supports dual redundant power supplies – “Power Supply 1 (PS1)” and

“Power Supply 2 (PS2)”. The connections for PS1, PS2 and the fail-safe relay are located on the

terminal block as shown in Figure 15 and Figure 16.

The RSG2000 Family can be equipped with either a Philips Screw Terminal Block or a Phoenix

Plug Terminal Block. The Philips Screw Terminal Block has Philips screws with a compression

plate allowing either bare wire connections or crimped terminal lugs. We recommend the use of #6

size ring lugs to ensure secure, reliable connections under severe shock or vibration. Both terminal

blocks have a safety cover which must be removed via two Phillips screws before connecting any

wires. The safety cover must be re-attached after wiring to ensure personnel safety. Refer to Table

3 below for a description of each terminal as well as sections 4.3.1 through 4.3.3 for wiring

examples.
