Power Requirements - Toshiba OIS Series User Manual

Follow the procedure given below for proper mounting:
1) Make a cutout of the required size. Panel cutout tolerance is + 0.1mm.
2) Put the gasket behind the bezel (see dimensional sketch for details). The gasket may be
sealed to the case using an adhesive.
4) Put the OIS60 unit through the panel cutout.
5) Insert the clamps into the case.
6) Pullback the clamps until they seat into the retaining slots.
7) Tighten the clamping screws in an even pattern until the OIS60 unit is secured into the panel.

Power Requirements

Supply voltage for OIS60 models is +24VDC + 10%, 3W maximum.
Power, input and output (I/O) 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.

A.

B.

C.
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 for the positive DC,
negative DC and Earth.
To make a connection strip about 1/4" 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.
OIS 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 pull out.
All the OIS 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
should be made to a central star point as poor site earths can introduce noise into a system.
