2.4Connect Power to the Universal Monitor

The Universal Monitor 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.

! WARNING

Check that power is removed from wires prior to installation.

! CAUTION

The Universal Monitor 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.

! WARNING

Be sure that the Power On/Off switch is set to OFF before installing any wiring to this unit. The switch is in the top left corner of the unit, just below the battery pack.

2.4.1Input Power Connections - Small Enclosure

To connect electrical power:

1.Run conduit and electrical wiring from building to the Universal Monitor.

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 7). Strip wires 1/2".

3.Secure the incoming electrical service wires to the Universal Monitor’s 24VAC input by sliding the wires into TB7, the 24VAC input terminal block. There is no polarity requirement when connecting to TB7. The ground wire must be connected to the earth ground terminal located on the side of the panel (see Figure 6).
