Power Connection
Every TPPL Controller and Expansion Unit is factory set to operate at a manually switchable voltage of AC 110/220 V
on single phase, 50 to 60 Hz power supplies. They can also be connected to DC 18 32 V SELV supplies with their
backup battery removed, or DC 24 32 V SELV supplies with a battery fitted
current).
TPPL Controller and Expansion Units each have a typical power consumption of less than 107 W, and they must be
directly connected to power supplies via a Main Isolator Switch that leaves protective earth (ground) permanently
connected. The circuit should incorporate a Residual Current Device (RCD) or Residual Current Circuit Breaker
(RCCB).
TPPL systems are not certified for connection to domestic or fluctuating power supplies.
WARNING
The system is normally supplied with the voltage pre-

voltage setting and correct as necessary. Remove the yellow label
when done.
WARNING ELECTRICAL SHOCK HAZARD
All power supplies must be hard wired and must include a circuit breaker (RCD / RCCB), and (close by and
unobstructed) a means of manually isolating and locking out the power supply without breaking the
protective earth (ground) connection.
Removable plug and socket connection is not permitted under any circumstance.
WARNING ELECTRICAL SHOCK HAZARD
Lethal current may be present in this equipment when electrical power is applied. There is a danger of death
or injury from electrical shock. Isolate power before opening electrical access panels. Ensure residual current
is fully discharged before touching live terminals.
WARNING
Honeywell can accept no responsibility for any damage or injury caused by incorrect or faulty wiring.
WARNING ELECTRICAL SHOCK HAZARD
Lethal current may be generated both internally and externally to the system. All installations, including
remote units and cables, must be connected to protective earth, and must be capable of remaining so when
the power supply is interrupted.
Protective earth is shown by the green symbol on the left.
