5 TPPR Electrical Installation
5.1 Power Requirements
5.1.1 Power Consumption
The power consumption of your system was calculated when it was ordered. See the supplied Certificate of Conformity, or
the fixed rating plate for details.
5.1.2 AC Power Input
AC Power input (if used) must be single phase AC 100 – 240 V, 50/60 Hz.
The mains supply requires an overcurrent protection rated in accordance with the rating plate on the specific system. The
supply must be a fixed installation, i.e. not plug and socket.
The supply must be able to be isolated by means of a lockable switch or circuit breaker, which must be suitably located,
easily reached and clearly marked as the TPPR disconnect device.
The wiring used between the isolator and TPPR must be appropriately rated and approved.
5.1.3 DC Power Input (excluding backup batteries)
External DC Power input (if used) must conform to the Input Supply Voltage given in Ch.20 TPPR Specifications, and it must
not be located inside the TPPR wall mounted enclosure.
The voltage supply requires an overcurrent protection rated in accordance with the rating plate on the specific system.
The supply must be able to be isolated by means of a lockable switch or circuit breaker, which must be suitably located,
easily reached and clearly marked as the TPPR disconnect device.
The wiring used between the isolator and TPPR must be appropriately rated and approved.
Ensure that the power supply is able to maintain sufficient voltage level for the connected field devices and to recharge the
backup batteries.
External DC supplies would normally connect directly to the DC-UPS input terminals, but other connection methods may be
used.
Installation must be in accordance with the recognized standards of the appropriate authority in the country
concerned. Refer to local, national and company regulations.
TPPR power supplies are supplied already wired. Do not modify any factory fitted cabling.
All power supplies must be hard wired and must include a suitable 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 should not be used under any circumstance.
