Electrical Connections - Pentair INVERTEMP FL Series Installation And Operating Manual

ELECTRICAL CONNECTIONS:

Connection of the power supply:
– Prior to undertaking any intervention inside the HP, it is imperative to disconnect the power supply from the HP: there is a risk of electrocution that can cause
damages, severe injuries, and even death.
– Only a certified and experienced technician is authorised to conduct cabling work in an HP or to replace the power cable.
– The power supply should match the voltage featuring on the information plate of the HP.
– The HP must be connected to an earthing connection.
Electric installation:
To ensure safe operations and to protect the integrity of your electric installation, the HP should be connected to the electrical mains according to the following
rules:
Upstream, the electrical mains should be protected by a 30-mA differential switch.
The HP should be connected to a suitable class C circuit-breaker (see the table below) according to the standards and regulations in force in the country where
the system is installed.
The power cord should be adapted to the power of the HP and the length of cable required for the installation (see the table below). The cable must be suitable for
outdoor use.
In the case of a three-phase system, it is imperative to follow the connection order of the phases.
If phases are inverted, the compressor of the HP will not work.
In public spaces, the installation of an emergency stop button close to the HP is mandatory.
The voltage must match the voltage mentioned on the HP.
The connections must be sized based on the power of the HP and on the installation state.

– Use the cable-gland and the pass-through provided inside the HP for the passage of the cables.
– As the HP is installed outdoors, the cable must pass through a protection sheath provided for that purpose. The power supply of the HP must be provided with a
protection system according to applicable law.
– The electric cables must be buried at a depth of 50 cm (85 cm under a road or a path) in an electric sheath (ringed and red). When a buried sheathed cable
intersects with another cable or a duct (water, gas...), the distance between the two must be greater than 20 cm.
