Emerson MC68HC16Z1 ユーザーズマニュアル

The Liqui-tect panel requires 24VAC for proper operation. Liebert recommends using the optional 

Transformer Module manufactured by Liebert or another UL-approved Class 2 power unit to obtain 

proper voltage. If the power unit is not a Class 2 circuit, it must be protected with an IEC 5 x 20mm 

time lag 2A fuse. For information, consult your local dealer, Liebert representative or the Liebert 

Worldwide Support Group.

To connect electrical power:
1. Run conduit and electrical wiring from building to the Liqui-tect panel.
2. Use copper wires only; proper wiring to use for 24VAC power is 18-22 AWG stranded and shielded 

(18 AWG is recommended—see Table 4). Strip wires 1/2".

3. Secure the incoming electrical service wires to the Liqui-tect panel’s 24VAC input by sliding the 

wires into TB1, the 24VAC input terminal block. There is no polarity requirement when 

connecting to TB1. The ground wire must be connected to the earth ground terminal located on 

the side of the panel (see Figure 5).

Check that power is removed from wires prior to installation.

The Liqui-tect panel is designed for use on properly grounded (earthed) 24VAC power, 50Hz 

or 60Hz. The ground wire for the power lead must be wired to the earth ground terminal (stud 

located next to the 24VAC terminal block).
This equipment is intended to be installed by a qualified and certified electrician who must 

review and approve customer supplied wiring and circuit breakers, verify correct input and 

grounded (earthed) connections to ensure compliance with technical standards and national 

and local electrical codes.

Be sure that the power wiring is disconnected from the Liqui-tect panel before installing any 

wiring to this unit.
