RATINGS
ADVERTENCIA
PF and PFQ Series plugs and receptacles are UL and CSA listed according to
DANGER
UL 1682 and CSA C22.2 No.182.1 These listings only apply for 300A and 400A
devices at 600V or less. 600A devices are not UL or CSA listed. WARNING! All
CAUTION
PF and PFQ devices are provided with manually operated auxiliary contacts that
must be wired to the coil of a contactor or similar switching device to prevent
accidental connection or interruption of live main power contacts. See schematic
AVISO
for safety circuit example. The ratings for auxiliary contacts are shown in Table 1.


INSTALLATION
PF and PFQ devices should be installed by qualified electricians in
accordance with all applicable local and national electrical codes.
Before starting verify that the power is off, that the product ratings are appropriate
for the application, and that the conductors meet NEC code requirements. Tools
WARNING
required for installation include 7/ 8" (22mm) wrench or socket, 5/16" (8mm) allen
wrench and 10 mm wrench for PFQ only.

General Notes & Precautions
1. To prevent short circuiting the heat shrink sleeves provided must be used
over lugs and terminals after wiring.
WARNING
DANGER
2. The PF and PFQ inlets and receptacles and handles are symmetrical and thus
they can be mounted in any of four positions provided that the locking cam on

WIRING INSTRUCTIONS
AVISO
The cable sheath should extend at least 2 in. into handle or junction box.
For Plug or Connector with Angled Handle or Receptacle on Box
or Inlet on Box
• Use straight type compression lugs with 9/16" or 5/8" hole.
• Run the neutral & ground wires above the phases.
• Apply heat shrink over lugs at terminals.
For Plug or Connector with Straight Handle
• Use 90° lugs with 9/16" or 5/8" hole. Arrange the 90° lugs to minimize the
possibility of lugs touching
• Run the neutral & ground wires above the phases.
• Apply heat shrink over lugs at terminals.
NOTICE: Lugs crimped on the conductors must be bolted on the terminals with
the supplied M14 screws and washers. In order not to transmit this torque to the
molding, contact bodies should be held with a suitable wrench when tightening the
M14 screw.
The phase contacts are lower to allow the passage of the ground and neutral
above the phases.

ASSEMBLY
Angled Handle to Inlet or Receptacle Assembly
1. Attach inlet or receptacle to handle body then open cover on handle.
2. Connect the conductors to the terminals as described previously in 'wiring
instructions.'
3. Attach handle cover using a 8mm allen tool and 6 screws supplied.
4. Compress grease coated cable gland by tightening hub.
NOTICE: The recommended torque to achieve IP 67 is 150 to 280 ft-lb
(200-400 N-m), depending on cable jacket material and diameter.
5. Then tighten the cable clamps.
Junction Box to Inlet or Receptacle Assembly
1. Attach junction box to conduit. Attach cover to junction box using bolts provided.
2. Connect conductors to terminals as described previously in 'wiring instructions.'
3. Mount receptacle or inlet to junction box cover using bolts provided.
Auxiliary /Pilot Contacts
In order to prevent disconnection under load electrical interlocking is required.
Failure to do so could result in death or serious injury.

CAM TO ENGAGE PILOTS
Typical PF/PFQ Control Circuit
PF: The four pilot /auxiliary terminals are numbered 1 to 4 and color coded.
Conductors must be stripped by 0.5 in (12 mm) and fully inserted into their respective
spring-assisted, tunnel type terminals. Tighten terminal screws until hand tight with
a 4 mm flat screwdriver. Recommended torque is 13 in-lb (1.5 N-m). Terminals will
accept flexible conductors up to 10 AWG (6 mm
PFQ: Eight pilot /auxiliary contacts are prewired and identified. Pilots are marked
P1 and P2, whereas auxiliary contacts are numbered 3 to 8. Conductors provided
have a cross-section of 14 AWG (1.5 mm
Mechanical Locking: PF Series
The cam has two positions:
Position 1: Unlocked, auxiliary/pilot contacts opened.
Position 2: Locked, auxiliary /pilot contacts closed. The plug is live and cannot be
removed.
Mechanical Locking: PFQ Series
The cam on the receptacle has three positions:
Position 1: Unlocked, auxiliary and pilot contacts opened. The cover or plug can
be removed.
Position 2: Locked, pilot contacts opened. The cover or plug cannot be removed
but pilot contacts remain open.
Position 3: Locked, auxiliary and pilot contacts closed. The plug is live and can
not be removed.
Position 1
Cam can be locked out in any of the three positions.

OPERATION
To ensure safe and reliable operation MELTRIC
used in accordance with their assigned ratings.
They can only be used in conjunction with mating receptacles or plugs manufactured
by MELTRIC or another licensed producer of products bearing the
®
WARNING
gy trademark.
DANGER
MELTRIC plugs and receptacles are designed with different keying arrangements,
®
so that only plugs and receptacles with compatible contact configurations and elec-
CAUTION
trical ratings will mate with each other.
Connection
NOTICE
1. Insert the plug into the receptacle. This unlocks the safety shutter on the
receptacle and allows it to rotate.
2. Rotate plug approximately 30° clockwise to engage the phase contacts and to
make the unit watertight. Turn the cam /mechanical lock to secure the receptacle
and engage the pilot contacts which energize the circuit.
Disconnection
1. Turn the cam/mechanical lock to disengage the pilot contacts and
de-energize the circuit.
2. Twist plug 30° counterclockwise to disengage the phase contacts.
Withdraw plug.

ACHIEVING RATED WATERTIGHTNESS
NOTICE: Proper steps must be taken to maintain water tightness at NPT fittings on
the plug handles or at the junction box. The use of a sealer tape is recommended.
IP 66 /67 rated ingress protection applies to the device when the plug and
receptacle are fully mated. When not in use the plug/inlet or connector/receptacle
can be kept watertight by utilizing the protective cap. Caps are fully engaged when
inserted into receptacle /inlet, rotated 30° clockwise and secured in place with the
locking cam.
Using the correct bushing and compression washer size is important.
The bushing must have as close a size as possible to the outer cable diameter.
The portion of the cable that passes through the bushing must be as circular as
possible to maintain ingress protection.

MAINTENANCE
WARNING
eliminate the risk of electrical shock. DANGER
MELTRIC products require little ongoing maintenance. However it is good practice
CAUTION
to periodically perform the following general inspections:
NOTICE
• Check the mounting screws for tightness.
ADVERTENCIA
• Verify the weight of the cable is supported by the strain relief mechanism and
not by the terminal connections.
DANGER
• Check the IP gaskets for wear and resiliency. Replace as required.
CAUTION
• Verify the electrical continuity of the ground circuit.
AVISO
• Check the contact surfaces for cleanliness.
Deposits of dust or similar foreign materials can be rubbed off the contacts with
a clean cloth. Sprays should not be used, as they tend to collect dirt. If any
significant pitting of the contacts or other serious damage is observed they should
be replaced.
