1. If replacing a single contact cartridge, remove the appropriate leads and

turn the plastic retaining screws to allow removal of the cartridge as shown

in Figures 4.25 and 4.26. Insert the new cartridge and position the retaining

screws to hold it in place. Reconnect the leads to the cartridge. Ensure that

the cartridge is in the proper configuration (the top cartridges are normally

closed, the bottom cartridges are normally open, refer to Figure 4.27). The

“normal” state is when the contactor is “off ” (open position).

To remove cartridge,

turn retaining screws.
