! CAUTION

Be sure that the power wiring is disconnected from the Liqui-tect panel before installing any wiring to this unit or changing input or output connections.

Input and output connections to the Liqui-tect panel may be made in any order—it is not necessary, for example, to make all input connections before making any output connections. Use copper conduc- tors only for all wiring.
