Power and communication wiring must be in accordance with Class I, Division 2 wiring methods (Article 501-
4 (b) of the National Electrical Code, NEPA 70) and in accordance with the authority having jurisdiction.
Please follow the instructions given below while making power supply connections for models:
Follow the wiring diagram on the sticker of the unit which shows terminals.
To make a connection strip about 7mm of insulation of the wire, turn the connector screw
counter-clock wise until the gap is wide open. Insert the wire all the way in and turn the screw
clockwise until it is tight.
Wire lengths should be minimum. Wires should run in pairs with a neutral or common paired with a
live or signal wire.
NTXS +24VDC model is fused internally with a self resetting 60V, 400mA fuse. It is recommended
that all input power lines be protected from product failure by a fuse or breaker.
Adequate strain relief must be provided for the power connector, to ensure that vibration does not
cause the power connector to be pulled out.
All the NTXS products are housed in a moulded ABS plastic case which eliminates any
electrical shock hazard. Hence Safety Earth is not required to be connected to the chassis of the
unit.
The DC ground is not directly coupled to Earth ground internally. The unit is designed to operate
properly whether or not the DC ground is connected to the Earth ground. We do recommend,
however, that if the DC ground has to be connected to the Earth ground, the Earth connection
