SAFETY INSTRUCTIONS
!
WARNING
As with all types of electrical equipment, dangerous voltages exist within the equipment
where the Liebert Distribution Monitor (LDM) is installed. For maximum safety, ensure
power is removed and circuit breakers/disconnects are tagged/locked out per all applicable
national, state and local electrical codes prior to working inside equipment.
The area around the equipment must be free of any debris or standing water.
All power and control wiring must be installed by a qualified electrician in accordance with
the NEC and all applicable national, state and local codes.
ONLY qualified service personnel should perform maintenance and/or service on the Liebert
LDM. When performing maintenance and/or service on any component, verify test equipment
is insulated and has been inspected prior to use.
To avoid damage to the circuit boards, personnel handling these components should be
wearing an Electrostatic Discharge strap or other approved protective device.
When replacing or installing a solid core Current Transformer (CT), power must be removed
from equipment to prevent damage to the CT and/or circuit board. If the CT is a split-core
design, follow proper electrical safety procedures.
These safety precautions are to be used in conjunction with NEC and local/state electrical
code.
