Class 2 Insulation:
No protective Earth is required and none should be fitted.
The host equipment must provide a suitable external over-current protection device such as: -
Fuse: 6.3A 240 Vac Antisurge (T) HRC conforming to IEC 60127
Or MCB: 8A, 240 VAC Type C conforming to BS EN 60898
The host equipment must provide adequate protection against contact to hazardous live parts.
Relays
Max current relay 1: 6A (non inductive)
Max Voltage relay 1: 260Vac (external supply)
Exclusive common
Max current relay 2: 4A (non inductive) Relays 2 and 3 share a common
Max Voltage relay 2: 260Vac (external supply) supply line and the loads can
Shared common with relay 3 have a combined total of 8A.
Relay 2 or 3 can switch a maximum
Max current relay 3: 4A (non inductive) of 6A provided the other is at 2A or.
Max Voltage relay 3: 260Vac (external supply) lower.
Shared common with relay 2
Max current relay 4: 3A (non inductive)
Max Voltage relay 4: 260Vac (Internal supply)
Common connected to Input "live"
Max current relay 5: 3A (non inductive)
Max Voltage relay 5: 260Vac (Internal supply)
Common connected to Input "live"
For compliance with the LVD, relays 2 and 3 common must be at the same potential as the supply voltage.
!
Warning:
Relays 4 and 5 outputs have hazardous voltages (Supply input voltage potential).
Ensure that all power is
switched off before
installing or maintaining
