FPC-02 Series Installation

PLEASE READ THIS MANUAL AND THE SAFETY WARNINGS CAREFULLY BEFORE INSTALLING

AND USING THE CONTROLLER AND SAVE IT FOR FUTURE USE

Installation notes

Familiarize yourself with the markings, warnings, components and terminology.

The FPC-02 power boxes and its accessories must be installed by a qualified electrician in accordance with local regulations and the requirements of the NEC (NFPA 72 ) and the CEC part 1.

WARNING: Ensure the power is disconnect from all circuits before mounting the power box and making any connections. Contact with components carrying hazardous voltage can cause electric shock and may result in severe personal injury or death.

Installer must ensure the installation of approved disconnect means, for all power supply circuits feeding this unit.

The power boxes are suitable for indoor wall mount installation only.

Ensure wiring according to the provided schematics using copper conductors only.

Make sure the wire gauge (AWG) is suitable for the circuit amperage draw, as specified in the

NEC/CEC table 1.

Ensure that the main breakers (fuses) are suitable for the heating systems rating (80% load).

Grounding means must comply with local regulations and CEC/NEC.

Ensure that the heating system/de-icing system connected to this unit complies with the UL 499 or

UL 515 & CSA 22.2 # 130.3 standard and is certified / listed by an NRTL.

Ensure that all wiring is rated for the application at 60°C (140°F as per UL 515 CSA 22.2 #130 clause 12 table 12.1.

Beware that any holes punched for conduit are to compromise the integrity of the enclosure ratings.

Ground fault equipment protection (GFEP)

The ground fault interrupter/residual current detector installed in this system is a Non class A GFCI, intended for equipment protection.

Familiar yourself with its operation and required setting.

The GFEP should be tested monthly. Please refer to the GFEP testing instructions on page 14 of this manual.
