2.3 Power Supply Wiring and Grounding
RS2000 series products support 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 14 and Figure 15.
RSG2200 series produ
cts 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 5 below for a description of each
terminal as well as sect
ions 2.3.1 through 2.3.3 for wiring examples.
