SYSTEM CONNECTION
For trouble-free installation we recommend installing the 640
system with a Memco 280 power supply. However in many
situations the 640 can be directly connected to the lift
controller or door operator.
Using a Memco Power Supply
A Memco power supply eliminates concern about the
electrical environment into which the 640 is being installed
and simplifies wiring. (See Figure 8.)
