Relay
Potential-free Relay changeover contacts N/O (Normally Open) and C (Common) rated 2A/240
VAC (resistive load) are provided as Relay output. Use external auxiliary device like contactor with
appropriate contact rating for driving the actual load.
Drive for SSR
DC Voltage level is generated for switching the external SSR (Solid State Relay). Connect (+) and (-)
terminals of SSR to indicator terminals 9(18) and 7(16), respectively. Use Zero-Crossover, 3 to 30
VDC operated SSR, rated approximately 1.5 times the actual load rating. Use appropriate Heat Sink
for load rating exceeding 10A.

POWER SUPPLY
(Terminals : 12, 13)
Figure 11.5
As standard, the indicator is supplied with power connections suited for 85 to 264 VAC. Use well-insulated copper conductor
2
wire of the size not smaller than 0.5mm for connections. Connect Line (Phase) to terminal 12 and the Neutral (Return) to
terminal 13 as shown in Figure 11.5. The indicator is not provided with fuse and power switch. If necessary, mount them
separately. Use a time lag fuse rated 1A @ 240 VAC.
For DC Supply, connect Signal (+) & Common (-) to indicator terminals 12 & 13, respectively.

The indicator is designed for installation in an enclosure which provides adequate
protection against electric shock. Local regulations regarding electrical
installation should be rigidly observed. Consideration should be given to
prevention of access to the Power Supply terminals by unauthorized personnel.
