2.3 Power Supply Wiring and Grounding
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 16 and Figure 17.
RSG2000 products 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 compression plates, 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 reattached after wiring to
ensure personnel safety. Refer to Table 5 below for a description of each
terminal as well as to sections 2.3.1 through 2.3.3 for power supply wiring
examples.
