•Using flexible steel armoured conduit makes it easier during installation and servicing of the Hydran M2-X. • All terminating connecting gland fittings to the Hydran M2-X must be liquid tight or at a minimum have an IP56 rating, with locknuts and sealing gaskets •The steel provides shielding against magnetic fields.
Page 27
A 10 A to 15 A circuit meeting these requirements must be available for the Hydran M2-X at the time of installation. The installation must be done in accordance with local wiring regulations. Disconnection is through an external circuit breaker or switch that must be installed on the mains supply line near the unit.
