Mounting and Installation notes

For mounting and electrical installation, the following notes should be observed.

A Mounting on DIN rail

No additional parts are required.

B Wall mounting

With four ellipse screws for holes with diameter of

4 mm x 6 mm

C Flush panel mounting

With HVAC Products ARG462.10 mounting kit

Mounting Instruction M 3351.1

The wiring can be made with standard cables. Shielded cables are recommended

only if the controller is exposed to strong electromagnetic fields (EMC).

• The PolyCool™ RWR462.10/ALG controller operates on AC / DC 24 V (max. 10

VA) extra low voltage and is short-circuit-proof

• The operating voltage must satisfy the requirements for safety extra low voltage

(SELV) conforming to EN 60 730

• The transformers used must be safety transformers with double insulation con-

forming to EN 60 742. They must be designed for 100 % duty. When using sev-

eral transformers in the system, terminals G0 must be galvanically interconnect-

• If voltages of more than AC 24 V +20 % (DC 24V +10 %) are fed to the low volt-

age terminals, the controller or other connected devices can be damaged be-

yond repair. Also, voltages exceeding 42 V represent an electric shock hazard

• Mains voltages up to AC 250 V may only be fed to the potential-free contact Q13
