Step 7 — Make Electrical Connections

WARNING

Prior to performing service or maintenance operations on the ERV unit, turn off and disconnect all power switches to the unit. Be aware that there may be more than one discon- nect switch. Electrical shock could cause serious personal injury or death.

IMPORTANT: Only trained, qualified installers and ser- vice technicians should install, wire, start-up and service equipment.

POWER SUPPLY — The electrical characteristics of the available power supply must agree with the unit nameplate rating. Supply voltage must be within the limits shown. See Ta- bles 3-5 for electrical and configuration data.

ELECTRICAL CONNECTIONS — The ERV unit must have its own electrical disconnect box. If the disconnect option has not been ordered from the factory, it must be field supplied and installed per local codes. See Tables 3-5.

If the ERV unit has an electric pre-heater factory installed, it will be wired through the ERV unit disconnect.

Low Voltage Wiring — Wire low voltage per Fig. 14. The field connection terminal strip is located behind the panel that is adjacent to the control box. The correct panel is marked with a green label stating “Attention: For field control of ERV, re- move this panel to gain access to ERV field control terminal strip.” The wires connecting to the field terminal strip can be routed through the nearest 3/4-in. hole and through conduit to the RTU, or they can be routed down the sidewall of the cabi- net using the wire pull provided and routed through the combi- nation curb to the RTU.

CAUTION

When routing wires in the ERV always keep them away from moving parts and sharp metal edges. Follow all local and state codes when routing the ERV control wires.

If the ERV unit is mated to a RTU, terminals C and G on the field control terminal strip of the ERV unit are connected to the corresponding terminals on the RTU cabinet. Verify the jumper is removed from the “ERV R” and “G” terminals; not doing so may damage RTU control equipment.

When the ERV is to be run as a stand-alone configuration, verify that a jumper is shorting the “ERV R” and “G” terminals

on the ERV field control terminal strip. This will enable the ERV to turn on and run.

If the HVAC unit has an integrated economizer or power ex- haust, it is sometimes necessary to provide an interface be- tween the HVAC unit and the ERV controls to ensure proper operation of the ERV’s supply/exhaust fan and energy recovery wheel motors. The 62E has discrete inputs for this purpose and damper end switches or relays may be used to coordinate the economizer and power exhaust operation with the ERV.

When an ERV is mated to an electro-mechanical rooftop unit with an economizer and a power exhaust, terminals C and G on the ERV field control terminal strip are still connected to the corresponding terminals on the rooftop unit cabinet (jumper across R and G needs to be removed). However, in addition, field supplied and installed end switches are required to coordi- nate operation with the unit. For unit economizer operation, it is necessary to install an Normally Open end switch (field pro- vided) on the economizer actuator and connect to terminals 5 and 6 (ERV Shutdown) on the ERV terminal strip. This will cause the ERV to shut down during unit economizer operation. For power exhaust, based on building pressure control, no ad- ditional ERV wiring is required, however if the ERV is to pro- vide power exhaust functionality then a field-installed Normal- ly Closed end switch is required to be installed between termi- nals 7 and 8 on the ERV terminal strip.

High Voltage Wiring — Connect high voltage wiring to the disconnect, see Fig. 14. Route the power wires in water tight conduit from the disconnect switch box to the ERV distribution block. To gain access to high voltage block, remove panel marked with label stating, “High voltage terminal block locat- ed behind this panel.”
