4-4. Precautions for wiring
If the monitor operates on AC or DC power or if an inductive load is used at the alarm contact, wiring work
is required.
The following cables are recommended for wiring the monitor with the power supply, signal cable and
contact.
<Recommended Cables>
For AC power
Solid wire/stranded wire: 0.2 - 1.5 mm
2
For DC power
CVVS: 0.2 - 1.5 mm
2
For signal cable (4 - 20 mA/0 - 1 V)
CVVS: 0.2 - 1.5 mm
2
For contact
Cable such as CVV (0.2 - 1.5 mm
2
) Up to 4 cores
<Cable Connection Conditions>
Connectable cable, bare wire length and connection tools are as follows:
- Cable: 0.2 - 1.5 mm
2
- Bare wire length: 10 - 11 mm
- Connecting tools: Dedicated screwdrivers manufactured by WAGO and equivalent (edge width 3.0 to 4.5
mm x 0.5 mm)
<Compatible Bar Terminal>
For a bar terminal, the following items are available. See the spare parts list for RKI part numbers.
- Bar terminal (ferrule): Model 216 Series (manufactured by WAGO)
- Crimping tool: Model VarioCrimp 4 (206-204) (manufactured by WAGO)
CAUTION
•
Be careful not to damage the internal electronic circuit when wiring. In addition, be careful not to
apply stresses on the monitor when (overweight) cables are installed.
•
The power and signal cables must be wired separately from the motor power cables.
•
When stranded wires are used, prevent wires from contacting each other.
CAUTION
The specified bare wire length must be observed when the wire insulation is peeled off.
•
Improper clamping of the wire due to a shorter bare wire length may cause defective electric
conduction or heating.
•
Catching the wire insulation due to a shorter bare wire length may cause defective electric
conduction or heating.
•
Exposing the wire due to a longer bare wire length may cause defective insulation or a short circuit.
•
Be careful not to break up the wire. If the wire is broken up when inserted to the terminal, this may
cause defective insulation or heating.
CAUTION
•
A bar terminal of the specified model must be used. Using other bar terminals invalidates the
warranty of the performance.
