• Tension may cause wire breakage, heating, or fire.
• Do not install in any place at a temperature of more than 40 °C (104 °F) or less than 0 °C (32 °F) or exposed to direct sunlight.
• Do not install in any place where acidic or alkaline solutions or special sprays are often used.
• Doing so may cause an electric shock or malfunction.
• Do not install it in any steamy place such as a bathroom or kitchen.
• Avoid any place where moisture is condensed into dew.
• Doing so may cause an electric shock or malfunction.
• Use standard wires in compliance with the current capacity.
• A failure to do this may result in an electric leakage, heating, or fre.
• Do not wash with water.
• Doing so may cause an electric shock or malfunction.

Parts list

• Make sure that the following items are included in the package.

Locally Procured Parts

All parts other than the Multiple Remote Controller Adapter are procured locally.
The items required will depend on the connection method. Refer to the example of use shown below.
(Example)

1. Switch ……………… Single pole, single action switch
   Caution Select a part with contacts for extremely low amperage.
   DC 5V or 12V is used at the contact points for the switch so there is a load of only approximately 1mA. Improper switch selection could cause improper operation.
2. Relay ………………. For relay use the specifications given below Operation coil
   Rated voltage: 12 VDC
   Power consumption: 0.9 W or less
   * Use the diode that is recommended by the relay manufacturer at both ends of the relay coil.
3. Tr ansit relay ……… When the wiring work as described in 6. Wiring Restrictions are required, this relay is used.
4. Control cable ……. The length of the electrical wiring for the PAC-SA88HA-EP is 2 meters (6-1/2 ft).
   To extend this length, use a sheathed 2-core cable.
   Control cable type: CVV, CVS, CPEV or equivalent
   Cable size: 0.5 mm 2 ~ 1.25 mm 2 (16 to 22 AWG)
   Don’t extend the cable more than 10 meters (32 ft).

CAUTION

1. The wiring should be covered by an insulation tube with supplementary insulation.
2. Use relays or switches with IEC or equivalent standards.
3. The electric strength between accessible parts andthe control circuit should be 2750 V or more.
