Overview; Installation Variant 1 - Porsche Home Energy Manager Manual

Overview

– the display and control elements and the USB
US
interfaces of the energy manager are safe to
touch for customers and accessible without
restrictions.
FC
– the maximum permitted cable length of 9.8 ft.
(3 m) per current sensor is complied with.
– the inputs for voltage measurement, the external
ESM
voltage supply and the relay on the energy
manager are secured with appropriate series
PTB
fuses.
f Please see chapter "Installation of circuit
breakers" on page 11.
TR
– when laying the installation cables, the correct
length and the product-specific bending radii are
RU
observed.

Should the installation environment require
overvoltage category III (OVCIII), the input side of the
external supply voltage must be protected by an
appropriate protective circuit (e.g. with Varistor) that
meets the locally applicable regulations.
Installation at high altitudes
Sensor supply cables that are installed in electrical
installations at an altitude of over 6,600 ft. (2,000 m)
or that must conform to overvoltage category III
(OVCIII) due to their installation location must
additionally be insulated using heat-shrink tubing or
suitable insulation tubing with a dielectric strength of
508 V/mil (20 kV/mm) and minimum wall thickness
of 0.016 in. (0.4 mm) along the entire length of cable
between the sensor output (housing) and the input
terminal on the energy manager.
