Chapter 3: Basic Connections
See the wiring diagrams to know how to manage the use of many phases from the main voltage
supply and how to wire loads in parallel.
NOTICE
For the big terminal blocks connected on the variable module (SSR), use a
tightening torque from 1.9N*m (16.8lbf*in) to 2.2N*m (20lbf*in) to fasten a wire
gage from 12AWG (diameter of 2.05mm or cross sectional area of 3.30mm
2 ) to
14AWG (diameter of 1.62mm or cross sectional area of 2.08mm 2 ).
Connecting an EDGE Variable Output module (SSR)
Before You Begin
IMPORTANT: An external or circuit breaker and a disconnecting switch must be installed to interrupt
power to L1 and N/L2 electric power lines before connecting the system’s main sector
input on the variable outputs (SSR). It must be in close proximity to the equipment and
within easy reach of the operator. It must be marked as the disconnecting device for the
equipment.
From the power source, follow the wiring diagram to connect the main sector to the variable outputs
(SSR).
We recommend using a DPST disconnecting switch in series with a breaker. In the case of the use of a
SPST disconnecting switch, connect SPST disconnecting switch to cut the Hot line with a Neutral circuit
case.
IMPORTANT: The SPST disconnecting switch circuit is allowed only in North America under 120Vac.
Over 120Vac in North America and whatever the voltage in International markets, only the
DPST disconnecting switch is allowed.
WARNING
Installation must only be performed by qualified service personnel.
CAUTION
Disconnect supply before servicing.
WARNING
Lock the enclosure when wiring is complete or when servicing. Use the nut and bolt
included or a padlock (not included) to lock the enclosure.
1. Locate the terminals “L1” on the EDGE Variable Output (SSR).
2. From the voltage source `”L1”, connect a wire to the terminal “L1” on the EDGE Variable Output.
3. Connect a wire from the load to the terminal “LOAD” on the EDGE Variable Output.
4. From the load, connect to the voltage source return “L2/N”.
5. From the voltage source `”L2/N”, connect a wire to the terminal “L2/N” on the EDGE Variable
Output. Use the same signal than the point 4.
Consult the wiring diagram choice according to the equipment to help you your wiring.
IMPORTANT: The maximum voltage on the EDGE Variable Output (SSR) is 240Vac. The maximum cur-
rent allowed is 16.66A at 120Vac.
