2.5 mm2 screw terminals.B4

Fusing:

fine-wire fuse 5 A, slow-acting, H pursuant to IEC 127, also protects the valve outputs and external operating signal.

External operating signal:

with mains voltage, max. 5 A resistive load (UL approved: 5 A for 120 V), max. 2 A for cos φ = 0.35 (pilot duty).

External fault signal:

fault signalling contact, max. 5 A for 264 V

Reset:

using a button on the device

Remote reset:

by applying mains voltage

Housing:

impact-resistant plastic

Gas type and inlet pressure pe:

External fault signal:

dry contact (not internally fused), max. 1 A for 264 V, max. 2 A for 120 V

Connections:

Lower section with connection terminals.
5 knock-out holes for PG 11 cable gland or M16 plastic cable glands are pre-prepared.

Maintenance cycles:

The tightness control requires little servicing. We recommend a function check once a year.
