Mounting And Installation - ICS Tunnel Master Jr Manual

Mounting and The following instructions will provide detail information on proper
Installation
mounting and installation of the Entrance Keypad (See Appendix A for
equipment layout. options.)
Relay Box Mounting
• All site wiring must be performed be a licensed electrician that must comply with all
local and national codes.
• The relay box must be securely mounted to the wall in the equipment room of the car
wash. The relay box is designed to be located in a dry, non-corrosive environment.
• The relay box must be located so that conduit connections can be easily made, and the
relays can be readily accessed.
Relay Box Wiring
• Install one approved 3/4" conduit from the Relay Box to the Entrance Keypad box
located near the front of the wash tunnel. All conduit runs should meet all local and
national codes. Conduits shall be properly connected and securely fastened to the boxes
with Listed conduit hubs, and should be tightened to the torque specs of the
manufacturer. Over torqueing may cause enclosure breakage.
• Electrician must provide a dedicated 110vac circuit to power the Relay Box
• Run a 14-3 cable to the 110vac terminal block. It is labeled with H and N for Hot and
Neutral, respectfully. There is a mechanical ground lug located on the back of the box
adjacent to the terminal block. It is labeled with the universal ground symbol.
Terminations for the shielded cable should be torqued to 35 pound-inches.
• Electrician must supply a separate 24vac and 120vac circuit to the common (C) side of
the upper and lower termination points of each relay respectively, then loop the
commons together to each relay. This power is to "fire" the solenoids and equipment.
• A separation of 110vac and 24vac shall be maintained for all field-wiring circuits. All
24vac circuits must be supplied by a class 2 transformer.
• Tighten all wires on the circuit board in the relay box to 20 pound-inches (2.3 n-m.)
Overtorquing may cause enclosure breakage.
• Relays in the relay box are double pole with independent commons so that each relay
can have two circuits running through it. Commons are independent to provide a power
source to switch two devices through either the normally open or normally closed
circuits.
• Relays circuits should be supplied with no greater than 120vac 15amp.
This 120vac MUST BE A SEPARATE circuit from the dedicated 110vac circuit
terminated in the lower right corner of the OEM Relay Box.
