• Explosions can be caused when
electricity provides a source of ignition
for an explosive mixture in the
atmosphere.
• Fires are caused by overloading
a circuit or appliance or by current
owing through high resistance due to
faulty wiring, setting re to insulation
and surrounding materials.
• Electric shock/electrocution occurs
when current ows through the body
damaging the body.
• Electrical burns are caused by arc
blast or hot conductors.
• Indirect falls from ladders, scaolds, or

General Precautions Electrical Hazards
• Disconnect any devices from RCU Bus and
de-energize power supply prior to installation.
Failure to abide by the installation and operating
instructions may result in re and other hazards
• Comply with the terminal
specications as approved in the device pinouts as
per datasheet and dened on approved wiring
schematics Modication of electrical leads or
improper termination than where it is supposed to
be connected can cause damage to the unit.
• Device terminations shall be legibly labeled or
marked to indicate its purpose.
• Always follow the correct input/output
connections to the device based on the approved
design.
• Device should not be terminated with any high
voltage wiring. Do not mix the use of low voltage
and high voltage cable in the backbox and/or
conduit to pull wires. Wire run for Glass Panels and
Thermostat should be separate from any lighting
or HVAC loads.
• Electrical wires entering boxes,
cabinets, or ttings must be protected from
abrasion.
• All devices and all associated test leads, cables,
power cords, and connectors shall be visually
inspected for external defects and damage before
the equipment is used.
