369 MOTOR MANAGEMENT RELAY – QUICKSTART GUIDE
The 369 can be connected to cover a broad range of applications and wiring will vary
depending upon the user's protection scheme. This section will cover most of the typical
369 interconnections.
In this section, the terminals have been logically grouped together for explanatory
purposes. A typical wiring diagram for the 369 is shown above in FIGURE 2–4: Typical
Wiring on page 2–10 and the terminal arrangement has been detailed in FIGURE 2–3:
TERMINAL LAYOUT on page 2–9. For further information on applications not covered here,
refer to the 369 Instruction Manual, or contact the factory for further information.
Hazard may result if the product is not used for intended purposes. This equipment can
only be serviced by trained personnel.
VERIFY THAT THE CONTROL POWER SUPPLIED TO THE RELAY IS WITHIN THE RANGE
COVERED BY THE ORDERED 369 RELAY'S CONTROL POWER.

369 POWER SUPPLY
HI
LO
The 369 has a built-in switchmode supply. It can operate with either AC or DC voltage
applied to it.
Extensive filtering and transient protection has been incorporated into the 369 to ensure
reliable operation in harsh industrial environments. Transient energy is removed from the
relay and conducted to ground via the ground terminal. This terminal must be connected
to the cubicle ground bus using a 10 AWG wire or a ground braid. Do not daisy-chain
grounds with other relays or devices. Each should have its own connection to the ground
bus.
The internal supply is protected via a 3.15 A slo-blo fuse that is accessible for replacement.
If it must be replaced ensure that it is replaced with a fuse of equal size (see FUSE on page
5–60).
The 369 display can be separated and mounted remotely up to 15 feet away from the
main relay. No separate source of control power is required for the display module. A 15
feet standard shielded network cable is used to make the connection between the display
module and the main relay. A recommended and tested cable is available from GE Multilin.
The cable should be wired as far away as possible from high current or voltage carrying
cables or other sources of electrical noise.
