INSTALLATION ENVIRONMENT • Locations exposed to direct sunlight • Locations whose ambient temperature is outside the allowable range of 0 to +50°C (32 to 122°F) • Locations whose ambient humidity is outside the allowable range of 35 to 85% RH • Locations subject to drastic temperature change where condensation may occur • Locations with corrosive or flammable gases • Locations with excessive dust, salt, iron powder, or soot • Locations subject to direct vibrations and impacts • Locations subject to splashes
INSTALLATION PROCEDURE This section describes how to attach a connected unit directly to a panel, to a DIN rail, or to a DIN rail with an expansion unit spacer. ■ Attaching a unit directly to a panel Attach a metal fixture for screw tightening to a KV Series basic unit with set screws. Then, attach the basic unit with a metal fixture directly to the panel.
■ Attaching the spacer to the expansion unit Insert the upper claw of the spacer into the upper groove of the expansion unit and press the lower claw of the spacer until you hear a click. ■ Attaching the spacer to the DIN rail Lower the sliding tabs at both sides of the spacer and insert the upper claw of the spacer into the upper side of the DIN rail. Press the spacer onto the DIN rail and raise the sliding tabs until you hear a click.
■ When I/O signal lines cannot be separated from the wiring for power In such a case, perform grounding on the KV side using batch-shielded cables. (In some environments, grounding should be performed on the reverse side of the KV.) KV Shielded cable Sensor Input RL Output 24 V DC Ground ■ Terminal The terminal screws used are M3. When performing wiring with crimp-style terminals, use the following ones. 6.0 maximum 6.
Note 1: Use a load coil whose rating is less than the contact capacity. Note 2: Use a diode whose peak inverse voltage is 10 times or more the circuit voltage and whose forward current is not less than the load current. Note 3: Individually attach diodes, varistors, and CR circuits directly to the relay coil terminal. CONNECTING KV SERIES EXPANSION UNITS • Connect a basic unit and an expansion unit with an expansion cable. • An expansion cable approximately 60 mm long is provided as standard.
CAUTION Be sure to turn off the power before connecting or disconnecting expansion cables. If they are connected or disconnected while the power is on, the units may be damaged or fail. Note: Keep noise sources such as power cables and electromagnetic switches away from expansion cables (300 mm) as much as possible. Connection methods 1. Peel off the tape stuck to the right side of the basic unit. 2. Connect an expansion cable to the connector.
